5.1 (pseudo) mix from HDV stereo audio

I have done lots of research on this....and the folks in the encore forum have helped me figure out how to render my 5.1 mix to a Blu-Ray disc.
However now I have an editing issue....
I used the Adobe tutorial on how to setup a 5.1 sequence....I setup a new 5.1 master sequence, and told it I want 6 5.1 channels. I then copied the same audio track to each of the 6 channels in the project window. If I use submix channels, I guess you don't get the front/rear puck per the tutorial so I need 6 masters? It is clear that you need to choose 5.1, but not so clear on if you are importing stereo audio, how many master and submix tracks to setup.
I want to take my stereo channel mix, and "spread it" across the 5.1 sound stage. I know this is not true 5.1, but I don't care. I have done this with a much lesser NLE and if the rear channels are low, it provides a nice mix.
I think I am missing some of the steps though....do I need to separate my stereo captured HDV audio into mono or just leave it as stereo???
And regardless, once I had my 6 channels, and moved the pucks around, it was not outputting 5.1 to my PC speaker system. It is a 5.1 setup with a Creative X-FI titanium sound card. I do get 5.1 during editing from my other NLE.
I have read all the help files about choosing my audio hardware betweem WDM sound and Creative ASIO. However neither choice provides me audio out of my rear speakers during editing.
I then read that I need to setup my audio output mapping....and I need to "Drag the desired sequence channel tile into line with the desired hardware channel in the list." However I only have Speakers listed twice....and they only appear to be left and right.... Even though I have 6 audio channels in the sequence and a 5.1 sound card and speaker setup.
So the questions are:
1) What do I need to change to hear 5.1 audio during editing.
2) For what I am trying to do, should I be splitting my captured audio into mono channels or leaving it as stereo.
3) How do I setup my 5.1 sequence in order to achieve my goal.
I apologize if this is something simple. I have done the reading and research and cannot get it to work...
I feel like I am pretty close to being able to transition to this much more powerful tool. The video side is pretty straightforward. However I am having issues on the audio side.
If this was CS4 and a photo question, I could probably answer that!!!
Thanks,
BJBBJB1

Bill,
I typically do not resurrect old threads but there is so much good stuff here, I could not see starting a new thread!
I have been using this pesudo 5.1 technique with great success! However, the constant issues I have with transitions and having multiple audio tracks is really weighing on me. I am constantly creating audio sync issues when I insert transitions, or nudge an audio track by mistake, etc..
I am wondering if you have had much luck with any approach that limits the number of audio tracks.
Something I am toying with is having a 5.1 master track and feeding it my straight stereo input. Then moving the puck about one third of the way back from the front soundstage, and then using the center channel control to boost the center to a good level. This gives me a bit of a rear channel, a stereo soundstage, and I can control the center channel. Of course I cannot apply a delay to the rears using this method, but that is a minor loss.
However I do miss the very discrete mix for the front, center and surround of the other method. So is this the best I could do given my current goal of limiting the number of audio tracks on the timeline?
If I could feed two or three submixes with one stereo track source, that would be nice and allow me to do what I want with only one stereo track on the timeline, but I don't think you can do that can you?? If you could keep the puck available on the audio track that then feeds the submix, that would also help. But as soon as you assign a track to a submix, you lose the ability to control the soundstage for that track. All control passes to the submix unless I am missing something.
The bottom line is any time I have 2 or 3 audio track copies of my original audio source spanning an hour or more, it gets unwieldy. I am okay using additional audio tracks for music or sound effects, as they are short in length.
As always, any ideas most welcome!
Bill

"Up Mix" from 2-channel "Stereo" audio content to 5.1/7.1 Surround

Hello,
This is a feature that I had strongly hoped would make it to Media Center in Windows 8, but didn't. Please consider this for a future update and/or the next version of Windows...
Feature Request: "Ability to Configure Stereo Up-Mix Capability in Windows Media Center and/or Windows Media Player from 2-channel Stereo to 5.1/7.1 Surround so Stereo MP3/WMA audio files output to *all* speakers in my system, not just the left and
right main speakers."
More information:
My audio content (MP3s, WMAs, etc.) are of course all 2-channel stereo format (left channel, right channel). My home theater PC outputs to my home theater receiver (which is a 2012-model Sony 5.1/7.1 receiver) via HDMI. When I play
2-channel music (MP3s, WMAs, etc.) from Windows Media Player (WMP) and Windows Media Center (WMC) both in Windows 7 and Windows 8, I only hear music from the left and right main speakers, *not* the subwoofer not the rear surround speakers.
In order for this to happen, WMP/WMC would need to "up mix" the stereo signal to take full advantage of my physical speaker configuration (as specified in my Windows' Playback Devices configuration, which Windows is able to discern from the capabilities of
my receiver). Media Center even has an Audio setup in which the end user configures the audio configuration to either Stereo, 5.1, or 7.1 yet music is still output over only two channels!
I would like to see WMC/WMP either "automagically" perform the "up mix" or provide the user with an option to enable/disable it when 2-channel Stereo audio content is played.
Too difficult? Rhapsody.com already accomplishes this with its online audio player! Note that my audio equipment has the capability of forcing output to two channels between the PC and the receiver, which my receiver will then up-mix, but this
requires physically maintaining a dip switch and also several button presses on my receiver's remote... and this physical configuration must be updated each and every time I switch between audio and movies. Too much work when it could be accomplished
automatically by WMP/WMC!
Thank you for your consideration of this feature request!

The ability of windows to better control audio channel output is definitely an issue that needs to be fixed. It's really basic in this day and age where everyone and there mother has more than two speakers (i.e. 5.1 or 7.1). I understand that certain media
players, or certain decoders/channel mixers can be a workaround for this problem. But that's not enough. Today, we have many different sources for audio that are not just files on a computers:
1) Video/Movie files on computers (played through media center, MPC-HD or other)
2) MP3s/audio (played through same)
But there is also:
HTML5, webpages, Netflix, Amazon TV, Flash players, silverlight, etc. etc.
Hence why windows needs an option at the level of windows audio decoder to better control channel outputs over LPCM-HDMI! Either Mirroring L/R outputs to rear/side speakers, or, formal upmixing algorithms like Dolby Pro Logic etc., applied before
outputting over HDMI (Note I am NOT talking about bitstreaming!)
This is a trivial problem using WASAPI or ASIO. Why has windows audio not been properly updated since Windows XP!!
Recently, HTPCs and Media Centers are becoming many households primary source of entertainment.
Examples of some issues:
1) With no bitstreaming at all:
- Configuring HDMI audio "Playback device" to 5.1/7.1, and,
- Using a software decoder/media player to decode Dolby Digital, DTS, DTS-True HD, or Dolby True HD, and sending the data in LPCM over HDMI to the receiver/soundbar
-> works totally fine for outputting 5.1/7.1 surround from those sources
-> windows (i.e. software) completely fails in any ability to upmix 2.0 stereo sources to 5.1 or 7.1, or even mirror L/R channels to rear/side L/R channel for more room filling sound. Both these options should be available - upmixing with Dolby or other
for videos and mirroring/doubling the channels for music/MP3s.
Instead, windows audio sends silent channels over LPCM/HDMI when playing a stereo source. This has the added awful effect of not even letting my receiver upmix/mirror the outputs.
Hence, we need the ability to duplicate (for audio) and upmix (for videos) the L/R channels in a stereo source to the Rear L/R and or Side L/R channels through windows audio "playback devices" configuration before outputting over HDMI-LPCM!
In the day and age of 5.1 and 7.1 speakers this seems like such a BASIC feature that is missing.Otherwise, so many of us with an HTPC in our living room as our main source of media can't play music mirrored
through all our speakers, or watch videos with upmixed audio.
HDMI is the new standard, so this should really become an option.
I've done a fair amount of research on this problem, and do not believe there is any solution short of switching to optical (which I do not want to do because it can only carry 5.1) or, buying a fancy receiver instead of a soundbar with discrete rears and
a subwoofer (which I have) to do the mirroring/upmixing for me.

Why does compressor settings of aac audio, stereo, create 2 channel mono from 2 discrete audio channel movies?

Why does compressor settings of aac audio, stereo, create 2 channel mono from 2 discrete audio channel movies?

well depending on how your audio is brought into your system you can select it as two streams of mono or a stereo pair. In reality, unless it's mixed in stereo, that's just two streams of mono locked together. Other streams brought in via other means, can have a lot more audio channels, e.g. 8, 16, 24.
In your case, with what you're doing, two separate channels works best, so you can control the levels of two very different audio sources. If, for instance, you were taking the feed from the mixing board during a concert, you might want their stereo out. Otherwise you might be dealing with the 1.2 zillion channels that they're mixing live.
I like separating the tracks coming in. I work with people who prefer to lock them together. Locking means the tracks move together during editing. Ok, fine, but I'm usually dealing with different audio sources, like you are: a camera mic (safety on location) and a close mic (shotgun, lav). Or I have a shotgun source and a lav. I want to determine the best source audio for the shot. Sometimes it's a lav, sometimes a different feed from somewhere else, sometimes the shotgun, and sometimes a mix of two sources. But if they're locked together and pre-set to come out evenly from both speakers there no way for me to make a determination. The other guys like to cut and figure out the audio later.

Stereo Audio in from FCP to DVDSP

I can't seem to figure out how to create stereo audio when compressing from FCP5.
My workflow...
I export my timeline using compressor
I pick and export such as DVD 150 minutes best
I choose all so that I have MPEGS, AIFF and Dolby AC3
I generally don't change settings
Once my files are compressed I drag the AC3 file into the timeline.
There is every possiblity that I am doing it wrong. I've winged my way through DVDSP with little training and a complete lack of understanding of the manual--dang that thing is hard to make sense of!
Thanks for the help!

michelle:
your export seems to be correct. when you create a track in DVDSP, you can include either the AIFF version of the audio or the AC3. AC3 takes up less space on the DVD, so you can use it to save space on the final output or just to lower your overall bit rate.
now that you've got your assets, create a new DVDSP project, and go to the Assets tab and click the Import... button. select all three media items. display the default track and you should then be able to drag the audio and video into its timeline.
however, if that's not working, why is that? does the audio appear (in green i think) in the track's timeline and when you play it back you just don't hear anything? or does the track reject the action of dragging the AC3 media into it?
also note that the upper portion of the track is for video, the lower parts are for the audio (primary audio, then going down the list for alternate languages).
if none of these are your problem, post more details so we can get you fixed up!
later,

Flash audio controls is gone from the Windows audio mixer.

Flash audio controls is gone from the Windows audio mixer. The sound is, but I can not control it separately from the browser. Previously, there was a separate flash and a separate browser. When I use FF3. *. Flash Player audio option was, but the new FF versions do not. For me it was very comfortable and loved.
How can I repay such opportunity? and whether there is still a possibility?

Thank cor-el, but it did not help. I tried everything ( I installed it all over again, several times , clean cookies I'm using [[BetterPrivacy 1.68|BetterPrivacy 1.68]] add-ons clean cookies ... ), but the problem is not in the Flash Player to crash. It works. But I can not manage alone plugin container volume and alone audio browser.
I am not a programmer, so I do not know how I can change it yourself.
Maybe someone already has it done? I would be grateful if you divide.
Sorry for my bad English. Here's screen shot if I can not clearly say:

Analogue Stereo Audio Output from the New Mac Pro

Does anyone know what the analogue stereo audio output from the new Mac Pro is? From the specification, there appears to be a stereo output for headphones, but it is unclear what other audio outputs are available and whether a stand-alone amplifier is required to drive small stereo speakers. Yan (UK)

It is line-level. You will need powered speakers or an amplifier.

How do I set up stereo audio tracks as default in Premiere using the ProRes 422 codec?

Forgive me if this has been asked many times before. I have searched but can't find anything that explains it in language that doesn't require an advanced degree in computer engineering.
I am a recent convert for our beloved FCP 7. I am learning to love Premiere dearly - but the audio part of it drives me nuts.
I have exported from FCP a series of files as ProRes 422 movies with stereo audio tracks. I want to bring them into Premiere in the same way. But when I do it squashed everything into a single audio file.
This plays havoc with the panning - especially in mixes that have stereo music mixes. Apart from that it just confuses me.
Also. when I create a new project from scratch in Premiere and I select the custom ProRes 422 setting it only allows ProRes 422 mono audio. I don't see a codec for anything else (ie. stereo).
Am I missing something?
I have looked in all the preferences areas and can't find anywhere to change this. I just want to be able to import simple, basic two track audio (and have it show up the same) as I would in FCP, ProTools and the myriad other editing programs I use.
I also want to be able to set up a basic two track stereo timeline/sequence without having to reinvent the wheel.
Many thanks for any help and your patience. I am slowly tearing my hair out and spending long periods sitting in the corner hugging my knees and weeping.
My specs. Preferred editing codec: ProRes 422
Premiere pro version CS6 (6.05)
Thanks again.

Go to the Project Panel, select all clips and rightclick/modify/audio channels.
Set it to 2 tack and mono.
When you drop the clip onto the timeline the stereo will come in on two tracks.
You can also set this to default in the Preferences under Audio (before importing the clips) (Stereo set to mono).

Zoom H4n Stereo Audio Plays Only Left Speaker - How to Double It?

Hello Everyone,
I've been working on a few projects and noticed that the audio captured by the Zoom H4n will preview in both speakers (and before I drag it to the timeline I can right click -> Modify ->Audio Channels and get all the options there as well as hear it from both speakers) but as soon as I drag it onto the timeline it will only play through the left speaker.
Any ideas of either where I'm going wrong or how I can double the audio? It's all already cut together so I'm hoping there's a fix that is semi-time efficient to apply lol. Thanks so much for your help,
-Karl

Glad that helped! Next time, you can use the Modify > Audio Channels command to handle this before editing. If you only have audio on the left channel of your stereo source clip, or don't care about what's on the right, you could set the stereo audio to be treated as dual mono. When you put the mono source tracks into a sequence with a stereo master track, the mono source will automatically be routed to both stereo output channels. You can then use the Pan knobs in the Audio Mixer to position each sequence track in the stereo spread. This has to be done before you use the source clip in a sequence, however.

Recording my mix from my dj set ?

Heres my gear.
2 turntables
vestax pro 6 mixer
studio amp
Maudio fast track interface
very simple set up. im coming out of my mixer to the interface then from the interface I'm going into the mac. using rca from the mixer to 1/4" to interface is the cable. Sounds really bad and when i record and low. Can anyone help?

Couple of options:
A) Get a better interface. The FastTrack is essentially the cheapest proper audio interface on the market. I had to monkey with the one we use at my church to record sermons before I got it to sound any good. Since your mixer out is stereo, you want a device that can properly transfer stereo from your mix out to a stereo track in Garageband.
B) If the first option is not possible, the way I got our audio to sound good coming out of the mixer is to send it through the XLR microphone input in the FastTrack. You get a much higher input level that way, but it will not be stereo.

I want to record live stereo audio (using Mobile In)

with the new 30-pin connectors for iPad and iPhone making it possible to record stereo audio (like Line6 Mobile In), I'd like to record in stereo to iMovie on my iPhone4.
Does iMovie use Core Audio? If so, then this would be a great feature to add if it isn't there already. I haven't found a way to record stereo digital audio into any camera/movie app yet...
thanks
Jeff

It all depends on your expectations. A USB condenser mic is a good way to start. If you want better quality, you'd want to use several mics running through a mixer. If you want to be able to mix after recording, you should look into an audio interface with several channels that will allow you to do a multitrack recording in GB.
Another idea: are you using a PA system? Then feeding the audio from the mixing console might be a good idea, maybe with an additional track capturing the live audio and the audience reaction with an extra mic.
Possibilities are plenty and not so confusing when you think them through ...

Creating 5.1 surround sound out of stereo audio

Hi,
I'm new to surround sound editing, so for the past few weeks I've been searching through internet how to create suround sound for my movie. I have a whole movie already done in Premiere Pro 5 (every scene in it's own squence). In these sequences I have stereo audio clips that create a complete stereo sound, but since this movie is going to go on film festivals I have to create surround sound.
Through my reasearch I came across many explanations of how to create it, but the more I read the more it confused me so I decidet to ask for help on this forum.
1. Is it posible to create surroundsound directly out of stereo audio (I know that the sequences that you are working in has to be set to surround sound) that I have in first, second and third chanel, that have surround sound controls above them in Audio mixer?
2. I know that in 5.1 chanels you can only inport 5.1 surround sound tracks. My question is, do I have to take each stereo clip, transform it in mono clip and then create a stereo clip out of that mono clip?
3. Did I completly miss the whole concept of creating surround sound and that I would have to do it diferently?
Thanks for helping out, Jaggarjack

To output to DD 5.1 SS, you will need an Encoder, like the Minnetonka Audio SurCode DD5.1 SS plug-in.
You can also use Audition (do not know about SB) to create 6-channel files (usually WMA w/ either 5, or 6 discrete channels, depending on how you handle the LFE). Still, to use such a set of files with Audio-Visual material, you will need an Encoder. Minnetonka Audio has others, like the SurCode DD 5.1 SS stand-alone and the DTS stand-alone.
If you have disassembled the original audio streams into mono sources, you can create faux 5.1 SS, and with a little work, it can be quite convincing. The 5.1 controls in a 5.1 Master Project, can be very useful for "creating" your sound stage. You can also use those to feed certain frequencies from other sources to the LFE, and to the Center channel. With good stereo in the Front speakers, you should already have a decent phantom Center, and can punch that up even more.
I would recommend starting with the Help File for "Surrond Sound," to get the basics down, plus the mechanics in PrPro. HERE is a little sample. You might also want to see the links in this PrPro-Wiki Search for more material.
The Recording Academy's Producers & Engineers' Recommendations for Surround Sound Production is useful paper.
I recommend three books:
Surround Sound, Second Edition: Up and Running, Tomlinson Holman (cannot find my copy for ISBN)
Instant Surround Sound, Jeffery Fisher, CMP Books ISBN 1-57820-246-9
Basics of Video Sound, Des Lyver, Focal Press ISBN 0-240-51561-7
That would be a good start.
Happy reading, and up-mixing,
Hunt

Advice on recording vinyl mixes from 2 X turntables using Adobe Audition.

Hi,
I am a creative cloud member using the apps mostly for website design. I have a large collection of vinyl records. I am looking to digitize some 30 minute vinyl mixes from two technics and mixer and was thinking of using the Adobe Audition App which I can download to my laptop. Any advice to get me connected and started greatly appreciated !

what kind of mixer are you using? from my experience, as a vinyl collector turned vinyl dj... going between 45rpm 7"s, 45rpm 12"s and 33 1/3 12" LPs (mono AND stereo). good to know your mixer and your outputs on the analog side. i have found that to be the easiest way to bypass the heavy restoration work.
for relatively quick mixes. i just organize my audio files in the Files window and then start dragging and dropping into one track instead of any of those templates Audition has ready. The DJ Drop is completely ridiculous for someone like me who is spinning only 45s, recording from mixer booth to a tascam mxII recorder since I am doing that manually.
hope this helps.... somewhat? i am working on a 5 hour mix right now between 4 DJs and it's easier to just use regions instead of various tracks. Still a hell of a project.

How can I extract the two channels from a stereo track?

Hi,
I am writing a class that is able to draw an audio signal. It seems to be working well but I have a question. If I load a mono audio file I am able to draw it on a graph by using the byte[] array and everything is ok until now. That's the code:
void Draw(byte[] x)
            Graphics g=getGraphics();
            Graphics2D g2=(Graphics2D)g;
            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,                     RenderingHints.VALUE_ANTIALIAS_ON);
            for(int i=0; i<x.length-6; i++)
                g2.draw(new Line2D.Float(((i*(getWidth()-6))/x.length)+5, (getHeight()/2)-          ((x*(getWidth()-6))/x.length), (((i+1)*(getWidth()-6))/x.length)+5, (getHeight()/2)-     ((x[i+1]*(getWidth()-6))/x.length)));
The results is correct only if I have a mono track. Obviously when I get a stereo track the array becomes very large so here the question. How can I extract the two audio channels from a stereo track?
Thanks in advance.
Maurizio Di Vitto

A mono audio stream is stored [sample, sample, sample, sample], so just a list of samples in an array.
A stereo sample is interleaved in the same manner, so you get [left-sample, right-sample, left-sample, right-sample]
So every nth sample is the 1st channel, every nth+1 is the 2nd channel...

Recording from a stereo

How do I set up a voice memo recorder to record from my stereo? It should be possible (as the manual on the voice memo recorder briefly notes, and Apple confirms), by switching the button behind the microphone from "mic" to "line." But so far I've only succeeded in getting a message that no microphone is connected. Ordinarily I have an AV cable hooked up in a way that works for sending music from the ipod to the stereo -- connecting to the output jacks for a VCR, since all the others were in use by cd player, tape deck, and phonograph player). But when I try switching it to the input jacks and recording an old LP, I get only the error message, whether I plug it into the place where the microphone goes or instead where the earphones go (which I guess can't be right) on the ipod. Can anyone explain what configuration would work? Am I right in assuming I don't need any further wires?

Hi,
Are you trying to upload to your computer, the audio tracks on old LPs played on the stereo? If so, probably a better way to go is to get a second set of audio cables to go from the audio/line-out jack of either the phonograph or amplifier (depending upon your stereo's setup) to the audio-in jack at the back of your Dell (assuming you have a sound card installed).
I suspect if you use the iPod Voice Memo mic for recording the LP as it plays over-the-air so to speak, the quality won't be great. Better to input directly into the sound card the audio output produced by the stereo.
Depending upon what you want to do with the audio tracks once it's on the Dell, you can get other pieces of hardware, such as an M-box, or software to further clean up to sound, before you import it into iTunes (for example).

Stereo audio works only in FCE

I know this has been covered before but I would like some help to get from where I am now, out of the hole I seem to have dug.
Briefly, VHS video with HiFI stereo audio was converted with a Sony DCR TRV355 camera to DVPAL 720x576. Audio 16Bit 48Khz. Firewire cable plugged into the MAC running FCE4 and captured using 'capture now'. So far so good. I drag the clip to the timeline and the two audio tracks and the video track appear. The three names are all underlined. The two audio tracks are linked (the two arrows point to each other like an hour glass where the two tracks touch). The audio plays in stereo. I do nothing to this file, and quit FCE. Now, if I play that untouched captured file on a MAC or PC, in Quicktime, Windows Media Player, FLV whatever, the audio is mono, not stereo. Possibly only one leg of the stereo pair, or possibly left and right summed to mono, it's not easy to tell.
So I have two questions really:
One (not relevant to this problem as I cannot recapture the clip), what do I need to do differently next time to avoid this incompatibiliy?
Two, how do I get from here to being able to play the .mov file in any player in stereo, without degrading the picture? Thanks in advance.

... VHS video with HiFI stereo audio was converted with a Sony DCR TRV355 camera to DVPAL 720x576. Audio 16Bit 48Khz. Firewire cable plugged into the MAC running FCE4 and captured using 'capture now'.
This should have worked fine. A few questions -
Did you use the TRV355 as a converter between your VHS deck and your Mac, or did you record the VHS video to a tape in your TRV355 ... and later use FCE to capture from the TRV355 tape?
What Easy Setup did you use in FCE when you captured this video?
Exactly what versions of FCE, OS X and QuickTime are on the Mac you used to capture the video? Do you have QuickTime7 installed on this Mac?
Did you experience the "mono problem" playing the captured clip on the same Mac you used to capture the video, or did the problem appear on a different Mac?
When you experienced the "mono problem" were you playing the captured clip in QuickTime X or QuickTime 7?
For what it's worth, I have observed that if I play a video clip in QuickTime X that was captured on a Mac with FCE/QuickTime 7, for some inexplicable reason QT X does not fully recognize all the tracks in the clip. Mostly it thinks the clips are audio only, no video; but if I play the clip in QT7 it plays fine.
