From naturally extracted and expanded soundscapes to full cinematic big-stage enhancement, Halo upmix delivers with intuitive ease, all the control you need to fine-tune your surround mix to perfection. With unique centre channel management, including switchable dialog extraction, Halo is perfect for all types of production from archive restoration and TV through to the full 7.1 Feature Film experience. 'Halo is a truly versatile upmixing plug-in. It can both be saintly and angelic, with the down-mix (from the up-mix) being virtually indistinguishable from the original; or you can take the safety catch off and you can let its Halo slip and go off-piste, and be highly creative and controllably imaginative with the up-mixing.' Mike Aiton Mikerophonics Natural Extension Powerful real-time analysis of the original stereo material identifies and extracts locational cues, to naturally extend the panorama - without the introduction of any artificial reverberation, chorusing or delay into the downmix - leaving the inherent character of the original source intact.
Downmix Compatibility Because Halo generates a coherent spatial sound, you can be assured of a high-quality downmix. The 'exact' mode function ensures ultimate downmix performance where, as in TV re-purposing for instance, maintaining the relationship between the original, upmixed and downmixed versions is imperative.
Big sound For those situations that require an immersive cinematic dynamic, full control is available of all the relative surround balances, allowing any surround upmix to be crafted for a perfect blend into the complete 7.1 panorama. Detailed Centre Channel Control Centre channel extraction and control is provided for in a separate 'advanced' panel for use when dealing with intricate mixes, where no access to the original stems is available, offering unparalleled control - including neural network based dialogue extraction. Powerful Spatial Analysis Halo also includes a powerful spatial analysis view, intuitively showing the energy distribution of the upmixed panorama. Colour can additionally be used to indicate the speaker source for audio in any position, clearly indicating cases including phantom vs hard centre predominance etc. Phantom Centre LF Centre Divergence Hard Centre Optional 3D Immersive Extension (7.1.2 Dolby Atmos® bed track-compatible upmix/Amisonic Output) The 3D Immersive Extension introduces additional vertical controls via an expanded user interface including control over Ltm and Rtm placement for Dolby Atmos compatible placement. An additional real-time analysis view is also included for the vertical dimension, showing energy distribution of the output audio. The enhanced upmix algorithm allows for simultaneous use of all the original features including dialog isolation and individual channel output control.
The Halo 3D option is suitable for numerous applications including sound design, film score, restoration & archive, music and atmospheric soundscape production.

Upmix to 1st order Ambisonic (AmbiX format) for VR applications (3D extension required) Cross platform/Multiple format Halo Upmix is available in VST, AU and AAX formats & requires a surround-compatible plug-in host (5.1/7.1). Tom Marks Re-Recording Mixer, Warner Bros. 'For the mix of the feature documentary, 'I Am a Ukrainian: Personal Stories of a Revolution', I used the Halo Upmix to take the stereo music cues and spread them to surround. Most of the music in the film was delivered to the stage as 5.1 score. Halo Upmix did a very good job in matching the stereo cues to it.' Terrance Dwyer Owner Mixers Hollywood 'At Mixers, music is usually delivered to us as mixed, stereo files.
We use the Halo upmixer on all of our mixes to gently spread the stereo files into the 5.1 spectrum. We also do this with all stereo backgrounds. Unlike the previous plugin we used for this purpose which seemed to wash out 'localized' instruments, Halo allows us to do just enough to create a faithful, convincing upmix. We've come to expect a lot from Nugen and Halo delivers.'
Audio Media International Simon Allen 'NUGEN Audio has released a very professional product with Halo right from the onset. It was quite astonishing how extreme the surround image could be; yet the downmix was almost identical to the original.' Jacques Boulanger Creative Audio Post 'we're now using Halo Upmix for any film or television project in which we want to create a highly natural-sounding 5.1 upmix for home and theatrical surround audiences. At Creative Audio Post, we're dedicated to ensuring that every sound element contributes to a production's overall emotional soundscape, and Halo Upmix has become an essential part of our toolkit.

Doctor M's Stereo to 5.1+ Dolby Prologic II Upmix Guide - Original Trilogy. Doctor M's Stereo to 5.1+ Dolby Prologic II Upmix Guide Author Date 18-May-2010 Replies 26. Author Time 18-May-2010 5:22 PM — 2.0 to 5.1+ Dolby Prologic II Upmix Guide Sometimes you want to upmix Dolby 2.0 or PCM to more channels. Sometimes you may have an mp3 file or audio CD with content you want to add to an edit you are working on, but you don't want to work in stereo. This guide will help you do that. The best part is dialog will be in the center speaker and reduced or removed from your other channels, rear channels will have ambience and your subwoofer should kick a little.
Software needed: ffdshow is a DirectShow filter that supports pretty much any audio/video format you can imagine. It's constantly being updated, so grab the latest version. This guide was tested with Beta 7 revision 3154. Other versions may or may not work as well. GraphStudio ( is a fork of GraphEdit. While there is nothing wrong with the original, as far as I know it hasn't been updated in almost a decade.
The Method: 0) Rip your audio source to your computer. I hope you know how. Install ffdshow and unpack GraphStudio.
Your source audio file can be just about anything as long as you can play it in a directshow player. You should not need to set up ffdshow as the audio decoder for your source file, we won't be using that component. 1) Start GraphStudio, select file/render media file. Find your source audio and open it. 2) You will now see a graph that shows how the decoding components are chained together. Delete 'Default Directshow Device' box by selecting it and hitting the 'Delete' key.
If 'ffdshow Audio Decoder' is present, delete that as well. 3) Select Graph/Insert Filter. Select 'ffdshow Audio Processor', and click insert. Select 'File Writer', and click insert. You will be prompted for a location to save your file. Find a directory with enough space and make sure your file ends in.ac3.
Click the 'X' at the top of the window to close the filter selection screen. 4) Double click 'ffdshow audio processor'. (Except for the options below, all other filters in the left column should be unchecked.) If your source is a flavor of Dolby to start with, click 'Decoder Options' on the left and uncheck 'Apply dynamic range compression if available' on the right. In the left column select 'Dolby Decoder'.
On the right: Check 'Apply Dolby Pro Logic II decoding to all stereo sources'. The default 'Rear channel delay' is 20ms. You can adjust it if you want. On the left click 'Volume'. On the right: Click the check box for 'Volume'. Move the 'Master volume' slider to 50%. You might need the volume even lower.
Since the center channel will be louder than your left/right channels currently are, you must soften the volume or you will overdrive the sound and it will clip. If the source was not originally DVD (CD, mp3, etc.) try 25% first. If your source is not DVD, click 'Resample' on the left. On the right: Check 'Resample' 'Resample to' select 48000 Hz. 'Mode' select 'libavcodec highest quality'.
Check 'Resample always'. On the left, click 'LFE Crossover'. One the right: 120Hz is a good lowpass frequency.
You may want to experiment. If you want more subwoofer activity, you can adjust your gain, otherwise set it to 0db. If you want you can remove the crossed-over audio from the rest of your channels, but it's not necessary.
On the left click 'Mixer'. On the right: Check 'Mixer'. Set the 'Output speaker configuration' as desired. '3/0/2 - 5 Channels' and checking 'LFE' will give you DD5.1.
'3/2/1 - 6 Channels' with LFE is DD6.1 EX '3/2/2 - 7 Channels' with LFE is DD7.1 EX You get the idea. You can go lower, or have no LFE as desired.
Everything else should be unchecked. The 'Custom Matrix' is good if you want to do some custom audio mixes. Say you want only the dialog channel, you can output the center and leave the rest blank. Or say you want all the audio WITHOUT the center channel. You can do that too. On the left click 'Output'. On the right uncheck everything except: 'Supported output sample formats', check (S/PDIF encode mode) & select your 'Bitrate' as desired.
448 is good for 5.1, 384 is acceptable if you want to save space, 640 is acceptable but extreme. Check 'Allow direct-to-file output'. 5) Your source file box should already be connected to a decoder of some sort (it will vary by source). Find the last filter in the chain and using your mouse, drag from the out/output tab of that filter to the 'In' on the 'ffdshow Audio Processor'. An arrow should appear connecting them. Additional filters may be automatically added.
That's fine, just make sure they don't have strange settings that will interfere. If 'ffdshow Audio Decoder' has been added to the chain, go into the options (double click) and clear every checkbox (especially the mixer & Decoder Options). If the audio is pre-processed it may not upmix properly. Drag a line from the 'Out' of 'ffdshow Audio Processor' to the 'In' of your output file (the box will be whatever you named it). 6) Click the (play arrow) at the top. It will grey out. Wait until it reappears.
You should have a file to your specifications just where you wanted it. Give it a listen, you may need to make tweaks and try again. Notes: If there is interest, I may revisit this guide with info on outputting wave audio for encoding with 3rd party encoders (like Soft Encode or DTS). You can also use PowerDVD in a similar manner to access their official DPL2 decoder and DTS Neo:6. The Doom9 guide can give you additional (if out of date) information.
Are screenshots needed? 5/18/2010 by Doctor M Please do not repost this on other forums. At least until we've worked the bugs out.
M Author Time 18-May-2010 5:23 PM (Reserved for future use.). Dr. M Author Time 18-May-2010 6:02 PM (also reserved) Let me know how your results turn out.
M Author Time 18-May-2010 6:32 PM Thanks Dr M for this, and hell yea screen shots would be great, if it is not to much trouble. Thanks again. Author Time 8-Jul-2010 7:54 PM Hey Dr. M were you gonna add some screens to this baby?. Author Time 9-Jul-2010 12:52 AM Um, maybe?
M Author Time 9-Jul-2010 6:54 PM — Doctor M said: Um, maybe? Sorry man, just responding to your, 'Are screenshots needed?' Screens are always good, especially for people doing this for the first time. Author Time 27-Apr-2011 6:09 PM I was upmixing some stuff today and my own guide wasn't working. Here are somethings I ran into: AC3 file wouldn't load.
I have no idea why, it might be that I need AC3.ACM updated or something, but GraphStudio threw an error. The older version of the program GraphEdit had no issues. I opted to decode the 2.0 DD to WAV via BeLight (BeSweet). GraphStudio was fine with.wav audio. The outputted AC3 file was unplayable. I finally checked the file with DelayCut (an AC3 file fixer) and pretty much the entire thing was frame errors. Once corrected the file played just fine.
The reason: newer versions of ffdshow encode improperly. The last 'stable version', Beta7, while fairly old does produce errorless output. So you may have to downgrade your ffdshow to make this work.
I'll see if I can let the authors of the software know. M Author Time 27-Apr-2011 6:16 PM Thanks for the heads up DrM, I bet that is why jdobbs uses an old version of ffdshow for BD-Rebuilder, I have not run into any of the errors you had, probably because I have an old version installed for BD-RB. Author Time 29-Apr-2011 1:43 AM Welllll, after a friendly chat with the ffdshow folks, our problem is a feature not a bug.;-) They tell me that the AC3 is in a S/PDIF wrapper and the files plays back fine if you use AC3Filter. Just not with ffdshow(?) They did ask me to see if I could figure at what version the change was made, so they MAY fix the problem (unless for some reason it is necessary for people that actually use that feature for what it was intended). Anyway, on the bright side there is a work around for the newest builds that involves an extra filter and the extra step of creating a 5.1 (or however many channel) wave file and then using your favorite DD encoder on it. On the up side, it gives MAJOR flexibility to the guide to allow for more modern forms of DD, DTS and/or lossless tracks. (Which I suppose I could have included in the guide earlier).
I can't see asking people to install a 2009 build of ffdshow just for upmixing, so I'll give the ffdshow devs a chance to fix things. If that doesn't pan out this guide will get overhauled. (Probably with screenshots.) @darkjedi - I think jdobbs' reason might be that Beta7 is the most recent 'official' stable build of ffdshow. The rest are test builds. Yeah, it's been quite a while since the last official release.
M Author Time 29-Apr-2011 9:27 AM Well so far the above works well for me, but as I said it is probably because I am using the ffdshow that is required for BD-RB, but if and when you update the post, please let me know so I can copy your version 1 guide first, then grab the new, can't get enough guides LOL. Thanks DrM. Author Time 29-Apr-2011 8:08 PM Very nice guide, thanks Doctor M. I would also think it's safe to say that when dealing with audio that one should try to have the best audio quality available as a source for doing these things.I mean, you just can't polish a turd no matter how you paint it.LOL:). “Collective fear stimulates herd instinct, and tends to produce ferocity toward those who are not regarded as members of the herd.” ― Bertrand Russell, Unpopular Essays “When the debate is lost, slander becomes the tool of the loser.” ― Socrates Author Time 30-Apr-2011 3:11 AM True, but this is a frequently asked question by editors and preservationists. Deleted content is frequently not DD5.1. Non-DVD sourced audio can be very high quality but 2-channels is the medium's limit.
Most automatic upmix procedures can produce poorly localized dialog and other unpleasant side effects. So sometimes, yeah, even really bad sources need to be upmixed. M Author Time 30-Apr-2011 12:58 PM So would it be safe to think that one wanting to do this using various sources (i.e. Deleted scenes and such) should probably try use matching audio source quality to keep the output as consistent as possible?. “Collective fear stimulates herd instinct, and tends to produce ferocity toward those who are not regarded as members of the herd.” ― Bertrand Russell, Unpopular Essays “When the debate is lost, slander becomes the tool of the loser.” ― Socrates Author Time 30-Apr-2011 1:12 PM — Jetrell Fo said: So would it be safe to think that one wanting to do this using various sources (i.e. Deleted scenes and such) should probably try use matching audio source quality to keep the output as consistent as possible? It is not rocket Science, deleted scenes are not going to be as good of quality as the movie source, but when the movie source is 5.1 and the deleted scene is 2.0 this guide will show you how to make that crappy 2.0 into an acceptable 5.1 to mix into your edit, that is ALL this guide does, no more, no less.
And it is NOT about polishing a turd as you put it, it is about keeping an edit predominantly true 5.1, which would probably be about 99% of the edit, aside from the upmixed deleted scenes, and OBVIOUSLY you want to use the best source you can, but when it comes to deleted scenes you are at the mercy of what is available to you, are you not?. Author Time 30-Apr-2011 1:27 PM Sigh. Don't feed the trolls. M Author Time 30-Apr-2011 1:31 PM — Doctor M said: Sigh. Don't feed the trolls.
Sorry DrM, but you are absolutely right, but it just seemed to me like he was somewhat bashing your guide, and that is just uncalled for, this is a GREAT guide, and very helpful, if you take the time and learn how to use it. 1 more thing, it is FAR better to have the deleted scenes upmixed to 5.1, than do downgrade the entire audio to 2.0, now that is just plain stupid if you ask me, make the WHOLE movie suffer because you can't upmix a few small sections of film. Author Time 2-May-2011 11:18 PM ffdshow devs tell me the problem is fixed in rev 3835.
When that's actually released I'll give it a try. They also suggested that ffdshow may not be the most suitable program to use in this manner.
Unfortunately, they closed the bug report so I can't reply to get specifics why they said that. It's has me still considering rewriting to go to lossless 5.1 in this guide, but it's just a much bigger pain. 5.1 wave is an awkward format, the channel order is different from DD 5.1 so you have to re-arrange the channels, it takes an extra link in GraphStudio and an extra step to encode the final output. If anyone following this thread has specific knowledge why ffdshow isn't a good Dolby encoder, I'd like to find out more.

Upmix Stereo To 5.1
Maybe this question would be better asked at Doom9. Author Time 19-Sep-2011 7:11 PM — Is it possible that, instead of encoding to ac3, the output would be 6 (or 7, or 8) mono wav files? EDIT: Having tried a lot to get it right, I just end up with an ac3 file with FL, FR, LFE and three empty channels. Something doesn't work here. I'm using the latest version of ffdshow. EDIT 2: I got it.
Ac3filter needed some tinkering first. Author Time 20-Sep-2011 2:45 PM TK-949 said: Is it possible that, instead of encoding to ac3, the output would be 6 (or 7, or 8) mono wav files? EDIT: Having tried a lot to get it right, I just end up with an ac3 file with FL, FR, LFE and three empty channels.
Something doesn't work here. I'm using the latest version of ffdshow. EDIT 2: I got it. Ac3filter needed some tinkering first. Honestly, I've been on the fence with this. Doom9's original guide (which is sadly out of date) outputs to mono wav files and then lets you re-encode with your software of choice.
The advantage is you can then do DTS or more modern flavors of encoding. Also it wouldn't matter what version of ffdshow you are using. Besides, I've got to assume that ffdshow's on the fly encoder can't be nearly as good quality as dedicated encoders.
I think I may write an appendix that explains that method. Also, you shouldn't need ac3filter at all. M Author Time 14-Jul-2013 12:03 PM — Hey DrM just curious if you were planning any more updates to this whether it be with better methods, updated software, and you mentioned adding screens? Thanks edit - actually thinking on it I think it would be great to have both your guides updated complete with screens and have a downloadable pdf version to use when offline, but that is just me lol, anything you could do would be great. Author Time 14-Jul-2013 1:28 PM I wouldn't know where to start with a pdf version. But yeah, both guides do need an update. I was trying to talk the author of eac3to into adding dpl2 upmix to his program so it would all be one step and this guide would be pointless.
Other people weren't exactly clamoring for it so I wouldn't hold my breath. It's a bit of a shame since eac3to pretty much can do everything else. M Author Time 14-Jul-2013 1:33 PM — Well I know I would just love an updated version DrM so if you can this would be great and with screens, I will figure out how to take your info and create an offline pdf file for sharing, but hopefully you will update all programs, or maybe I am not updated lol, I know some of the options you mention I did not see on my program, like this one, 'On the left click 'Output'.
On the right uncheck everything except: 'Supported output sample formats', check (S/PDIF encode mode) & select your 'Bitrate' as desired.' Thanks DrM and looking forward to what you do here, and as I said, maybe I need to update on my end lol, but to this day I still use this, hell I just now created a custom DD 5.1 track for my Fright Night 2 BD, so thank you. Author Time 21-Jul-2013 7:16 AM Hi Dr. M I have followed your guide and created the following configuration, with minor tweaks for stereo/5.1 audio playback on MPC-HC. Ffdshow decoder configuration registry file:urlRequesting a small review of the settings, if the restored MP3 audio is close to original CD quality. You are most welcome to provide any tweaks.

I just bought a 5.1 surround sound speaker set for my computer in my bedroom. The rear speakers are next to me in bed while the front speakers are at the other end of the bed at my feet. While I enjoy the surround sound during movies that support 5.1 sound, I would like to have my rear speakers working when listening to podcasts, or other 2.1 channel sound. How can I do this? When I enable 'Speaker Fill' in the Realtek Hd Audio manager the sound only comes out of the front and center speakers with a few background noises that come out the rear ones. But since my ears are closer to the rear speakers, I'd rather have the sound come out of them. Let me know of any ideas!
Hmm seems like the only option is to set the rear speakers to 'Front Speakers' and change it to stereo in the Realtek HD audio. But still that take alot of steps and it doesnt not use the center speaker Thanks. In my case, I was having the same problem, my music and most videos were on 2.1 and I only heard 2 of the 5 speakers. Videogames and some videos had 5.1 so no problem. If you're running Win7 and you have no other than the default sound driver, there is an option 'Speaker Fill' that solves all problems! First, right click on the sound icon in the task bar (right lower corner), choose 'Playback Devices'. If you have only one sound output, it'll be the only one on the list.
If you have more than one then, while playing some music, you'll notice one of the device's volume bar moving, that's the one you should select. Select your audio input and click on 'Properties'. Then go to 'Enhacements' tab. There should be a checkbox with the 'Speaker Fill' in the middle. Select it and press apply. Worked for me perfectly, 5.1 sound on 2.1 music =D.
Intro: I spent several hours over the last couple days trying to figure out why there is no sound coming from the REAR speakers when playing 2.1 sources and such (streaming videos or music from online). 5.1 sound works in video games and DVD/Bluray, etc.
There was no SPEAKER FILL option in the most recent REALTEK drivers. Quick rundown of my problem: 5.1 audio only worked for 5.1 output sources, not for everything. Interesting details: CONTROL PANEL HARDWARE AND SOUND SOUND, click Speakers (typical output source. Where the sound comes from), then the Configure button. By default, it's set to Stereo (I just built a new computer, so this is where I was sitting). Set it to 5.1 Surround and it WORKS. For only one source (I would steam a channel on DI.fm and if I reopened that stream, it would revert back).
If I reopen anything or change a sound setting, it'll completely stop or it'll revert back to stereo sound. VERY clear difference, as with stereo, the volume out the front and center speakers is way louder than on 5.1, even on the same volume setting (I was using 50%). I would change it from 5.1, open a source, change it to Stereo, open a source.
There was a clear difference, and as said before though, it only works for ONE source. Keep in mind, Windows has an audio driver that has the SPEAKER FILL option, but as you're all probably aware, it's garbage. SOLUTION: CONTROL PANEL HARDWARE AND SOUND SOUND, click Speakers, then the Properties button, click the Enhancements tab (by default, Immediate mode is selected.
I left it checked, default position). Scroll down to the bottom of the list and check DTS Connect. You can even use the Room Correction enhancement to further produce a more desired volume from your speakers based on your configuration! Fixed the issue.
I can now restart my computer, play multiple sources, etc, without having to change anything in the sound options ever again! MOTHERBOARD: Asus Maximus VI Hero w/onboard Realtek HD audio.
If you have a creative audigy soundcard, in CMSS 3D/ CMSS Modes on audio console application see if you have ' Stereo Surround' option available (i have it on audigy support pack 4.0 drivers from danielK), this is better than those CMSS modes, in the way that it actually duplicates the channels on the rear speakers, instead of doing some funky stuff that the CMSS modes do, which i find doesn't sound too good, sound get distorted and is like,. The good thing of this it applies to all programs on windows. And real 5.1 sources aren't affected. The realtek 'speaker fill' option i have found (at least on my motherboard) it doesn't sound too good, like the cmss modes, so i would prefer to do it manually on each application(or try other solutions like enhancements tab mentioned on other posts): If you use media player classic (MPC is also included on CCCP and other codec packs) you can also edit the matrix in options, it's easy, and doesn't affect 5 channel sources. On foobar, on preferences/playback/dspmanager there is a ' convert stereo to 4 channels', just activate it and it just works (i don't think it uses center speakertough, you may need to download a matrix dsp if you need that one).
There are lots of various ways. I've tried too many to remember and found most of them lacking greatly in the accurate reproduction department. If you're looking for 'more noise' almost any of the above will work fine. I you're looking for more of an audiophile solution to using those speakers, it can be done but isn't exactly for the faint of heart.
To scare you off right up front, take a look at the screenshots below. Those are my mixer and patchbay setups. Yes, the mixer is playing two channel stereo at the moment, although it is impossible to tell. Anyway, start with 3rd order Ambisonics (jackd, ambdec, and a mitt full of plugins). Setup for a 7.1 system, even if you only have 5.1.
You can try to figure it out from the pictures, but it's just all too much to describe here. What's all this get you? Well, stereo.
That's the point. You end up with decoupled speakers, and a wider, deeper, and far better integrated image with a much bigger 'sweet spot'. I find it much less tiring.

Tom Marks Re-Recording Mixer, Warner Bros. 'For the mix of the feature documentary, 'I Am a Ukrainian: Personal Stories of a Revolution', I used the Halo Upmix to take the stereo music cues and spread them to surround. Most of the music in the film was delivered to the stage as 5.1 score. Halo Upmix did a very good job in matching the stereo cues to it.' Terrance Dwyer Owner Mixers Hollywood 'At Mixers, music is usually delivered to us as mixed, stereo files. We use the Halo upmixer on all of our mixes to gently spread the stereo files into the 5.1 spectrum. We also do this with all stereo backgrounds.
Unlike the previous plugin we used for this purpose which seemed to wash out 'localized' instruments, Halo allows us to do just enough to create a faithful, convincing upmix. We've come to expect a lot from Nugen and Halo delivers.' Audio Media International Simon Allen 'NUGEN Audio has released a very professional product with Halo right from the onset. It was quite astonishing how extreme the surround image could be; yet the downmix was almost identical to the original.'
