16 channel audio mixing

Hi
I'm building a unique multi channel audio mix for a synchronised projected video installation.
The most sensible way for me to mix my audio is in a 16 channel audio sequence.
But I cant see how to save off any form of the final edit.
The only save options I see are stereo , mono and 5.1 .
Anything in channels over these options are just ignored.
So a stereo export will ignore all channels from 3 to 16.
And 5.1 will not export any audio channels above 6 etc
And mono will not let me sellect which audio channel is chosen and there is no 16 channel save.
Is it possible to save off each channel as a mono file?
I am confused as to why you would offer this option if it cannot be exported even as 16 mono channels.
thanks rem

Gonna try to break this down so that anyone could understand.
You have 5 different video programs, apparently with no audio, that are going to appear on 5 different screens. Is that correct?
OR... did you create one video program that has 5 pictures in it... like picture in picture x 5?
You want 5 different stereo audio programs that you are going to somehow synchronize while these videos are playing... does that mean that you are going to be raising and lowering different audio programs to highlight different videos programs?
OR... is it all going to play at once?
You're either a genius or clueless as to how things work. Why don't you draw for us a picture so that we can better visualize what you're trying to do?

Left / Right Channel Audio mixing?

How do I mix the audio between the left and right audio channel?
I have a bunch of tape imported, but the audio is only in the left channel, so I need to either balance the audio, or duplicate the audio in the right channel... thanks in advance!

You should be able to do this by 'Exporting' your movie to GarageBand, and just making the one-channel audio the same on both channels.
Alternatively, if you want to do extensive tweaking manually, do the following:
0 - Download an audio editor such as 'Audacity'.
1 - In iMovie, select the video clip(s) which you want to 'repair', and then use 'Extract audio' to separate the audio from the video.
2 - Close iMovie, and use the usual Finder to locate your movie project, then Ctrl-click (or right-click) on the name of the project and choose "Show Package Contents".
3 - Look in the 'Media' file which then appears, and you'll find all your audio clips. Copy them to your Desktop.
4 - Start 'Audacity' and use File and Open to open the audio files, one by one, which are on your Desktop. Use these hints (intended for 'Sound Studio, but they work with 'Audacity', too, so click on 'Start Slideshow') to copy and paste one channel onto the other, then Save your work.
5 - Take those newly amended files on your Desktop, and copy them back into the 'Media' folder within your project (see 2 and 3, above).
6 - Reopen iMovie; the audio will now play correctly.

Premiere Pro 6/Mac - 5.1 audio mixer master channel order

The channel order of the audio mixer 5.1 master channel appears to be L, R, Ls, Rs, C, LFE. Can this be changed to one of the more common standards esp. L, R, C, LFE, Ls, Rs so that I don't have to reconfigure channels for every 5.1 clip I bring into the project.

Same thing here. See this post I made prior to seeing yours:
Output Mapping Preference for 5.1 Audio

CAPTURE AUDIO MIXES LEFT CHANNEL TO MONO

Everytime I capture now, or batch, or capture a single logged clip, the stereo audio comes in as mono, using only the left channel. The right channel audio is lost.
I searched the postings, and found this was happening with a lot of people, not just FCP 5.1 HD, but with FCE, too. No resolution or fix as far as I could see.
Anyone know how to correct this major bug? I really need stereo audio!
Thanks,
Norris

After a lot of research, and NO help from calling Apple tech support, I finally determined this (which has to do with HD/1080i/60 only -- I am not sure about NTSC settings):
In the Clip Settings tab, in "Log and Capture" (in HD) there is a little box next to the simulated VU audio levels meters. Click that box. It should toggle on/off two little lines that combine audio channel 1 and audio channel 2. When the little lines are there, that is STEREO. WHen they are not, in my FCP 5, it mixes both tracks to mono from channel 2 (Left).
As for your other question -- yes, you can manually go into the logs and change the settings, and then recapture.
a pain this is, huh? And no written mention of it in any manual.
NOW - as for previewing the audio while logging and capturing? I still cannot do that and have been waiting two (2) weeks for a reply from an Apple tech support guy who was supposed to be researching this for me.

Premiere CS6 - MXF export with 8 channel audio does not export my audio channels correctly

Hey Volks,
when i try to export an mxf file with 8 channel audio, premiere does a kind of main mix in channel 1 and 2 and channel 3 to 8 remain silent. It does not include my assignment of audio channels in the mxf file.
im very thankful for any idea...

Hi Dast Media,
Have you resolve the multi channel export?
I have the same problem...(the export it's ok but i hear only the first two tracks)
i need to export a MXF file with 8 tracks, 6 stereo and 2 mono.
Thank you for help!

5.1 Surround audio mixing

Does anyone have some recommendations for a good 5.1 surround audio mixing program?

You might be interested in my post from the Compressor forum on exporting from FCP to Compressor 2 for Dolby Digital:
Here is my procedure for a basic 5 channel project consiting of one stereo pair for the front speakers, a mono track for the center, and a stereo pair for the rear speakers.
First make a copy of your FCP surround project and name it as such.
i.e. My Project saved as My Project_surround
This will leave your original project untouched as a two channel mix should you wish to provide the user of your DVD with a seperate mix optimized for stereo only playback.
We will now be changing audio track assignments.
"My Project_surround" will now not play all tracks in your stereo audio monitoring environment unless you have a soundcard with at least 5 outputs.feeding a surround speaker set-up.
(or you use the Audio Mixer from the Tools drop down to monitor a downmix to two channels)
Open My Project_surround.
Let's assume that your timeline has a stereo pair "A1/A2" for the front L/R speakers, a mono file "A5" for the Center, and a stereo pair "A3/A4" for the rear speakers, Ls, Rs.
Use command "0" (zero) to open the project properties.
Go to the Audio Outputs tab.
Choose 6 from the Outputs Tab.
in the 1/2 grouping choose stereo (leave downmix at "0").
in the 3/4 grouping choose stereo (leave downmix at "0")
in the 5/6 grouping choose "dual mono" (turn off 6 using the downmix drop-down)
Click OK. (ignore the warning that pops up)
In your timeline we will assign your tracks to the appropriate output channels.
In the empty gray area next to the lock icon on track A1 right click, or control click, and you will get a dropdown menu
In the audio outputs sub menu choose 1 & 2.
Do the same for A2. (choose 1 & 2)
For A3 and A4 use the same procedure now choosing outputs 3 & 4.
For A5 choose 5.
Save the project.
In FCP export menu choose Export/Audio to AIFF(s)
(create a new folder on your media drive to hold your exported files)
You will get four files named after the project appended by: 1-2, 3-4, 5 and 6.
Delete "6" as it is a dummy/empty file.
Close your project.
Close FCP.
Open Compressor. In the batch window click on the speaker icon to open the "import surround sound group".
In the graphical interface either drag the file with the 1-2 suffix to the left speaker icon, or click the icon and choose the file.
Compressor will intelligently assign the left channel of the file.
Repeat by dragging or choosing the same file for the right speaker.
Compressor will intelligently assign the right channel of the file.
For the mono center file either drag the file with the "5" suffix to the center speaker icon, or click the icon and choose the file.
Use the same procedure for the Ls and Rs assignments.
Once done click OK.
Click to select your new group in the Batch window and from the dropdown menu choose "audio formats/Dolby 5.1"
Setting up your Dolby settings as a preset for this project is now up to you.

Mutli channel audio output via usb?

Hi there
I've had a browse through the support forums and can't find an answer to my question, so here it is:
I want to split the audio channels through the internal soundcard (I have an ibook g4) so that I can use audio mixing software.
Before I go out and buy some usb speakers, I was wondering if connecting speakers through the usb port would automatically do this - or, is there a way to assign an output route for each channel within the computer?
Any help is much appreciated.
Thanks

You'll need a "usb soundcard" that you can purchase from both apple store or just google it and I'm sure they have them all over the place (ebay, thinkgeek, ect). The built in soundcard is a 2 channel 44khz sound card with 1 output and 1 input via the built in microphone. Also, the only usb speakers I have ever seen are just usb powered, but they still plug in to the headphone plug.

Converting 2 channel audio from AVCHD to 5.1 audio for bluray

Hello,
I am looking to put AVCHD video files (*.MTS) containing 5.1 audio and 2-channel (stereo) audio onto bluray. I would like to convert the 2 channel audio to 5.1 audio, so that all of the files can be encoded onto bluray with 5.1 audio in Encore. I am using Premiere Pro CS6 version 6.0.3. I have tried to bring the MTS files into Premiere Pro, and convert stereo audio to 5.1 using Audition. However when the file is exported to Encore, upon transcoding there is no audio. Please let me know what is the best way to resolve this. Also, would I require something like Surcode plugin, or are there other ways to get around this? Thanks.

"Hi seaspray07,
"Hope this clarifies."
sorry it doesn't - it confuses me and I don't get why you want to do it this complicated way ;-)
1. If you have problems try to simplify your workflow. Why do you try to work with dynamic link in Encore? This isn't the classic route and I don't see why you need it in this case.
2. In a classical workflow you load final encoded audio and video files in Encore - in this case a .m4v and a .ac3 file encoded in Adobe Media Encoder.
3. To get this files you create a Premiere timeline with 5.1 master audio and load your clips onto it.
For all 5.1 clips Premiere will create a 5.1 audio track. For all stereo clips Premiere will create a stereo audio rack.
--> Keep in Mind you can't export a premiere audio track. That isn't possible even though this would be handy in a lot of situations. You alway only export the master audio track of a timeline. That master audio track get's it input from all audio tracks of a timeline. If there is a 5.1 audio track 6 channes are mixed to the master audio - if it's only a stereo track only L, R get's mixed up to the 5.1 master.
The master audio track is what you can hear if you play back a timeline.
4. Why do you want to convert stereo audio tracks into 5.1 audio tracks in the timeline? It needs much more filesize/ ram slows down your playback and gives you a unhandy viewing with lots of emty audio channels... Why dont store and view a stereo track as a stereo track?
5. If you have placed your stereo and 5.1 audio tracks on the timeline you can export the final mix via Adobe Media Encoder with the Surcode plugin as Dolby Digital 5.1 .ac3
"I sent the audio to Audition because I wanted to modify the audio file from stereo to 5.1, and bring it back into PrPro to combine with the video clip from the corresponding MTS file..."
That doesn't make any sense... because Premiere does it automatically for you without Audition. You simply have to do nothing - just place your stereo clip on the timeline and ready.
If you want to use Audition you have to have a real reason for it - for example do extensive audio work and mastering Tasks - conform it to R128 loudness or something like that.
Does this make sense to you? ;-)

5.1 Audio Mixer window

Can anyone tell me what the order of the meters are in a 5.1 project with a 5.1 audio master? The meters appear to be L, R, Ls, Rs, C, Lfe while the surcode plugin is looking for L,R,C,Lfe,Ls,Rs.
Is there any way to change the order of the audio mixer meter to ensure it matches with the surcode plugin?
Also, is there any way to send audio exclusively to the Lfe instead of to L,R,Ls,Rs and Lfe?
THX!

There are several questions and considerations here.
1. the order of the VU meters is predicated on the Audio Tracks (AT) in PrPro. At this stage of things, you place source material on the various AT's and then position them spatially. Effects (say a filter on an AT that you want to go to the LFE channel) also can play a role, but you make the decisions.
2. the "standard order of channels in say a WMA file, with the individual tracks set for stripping to discreet mono WAV elements, is as per below:
Track Number
Track Name
1
Left (front)
2
Right (front)
3
Center (front)
4
LFE
5
Left Surround (rear)
6
Right Surround (rear)
Now, with the SurCode DD 5.1 SS encoding, things change a bit. This does come into play if you go to a program, like Audition:
Track Number
Track Name
1
Left (front)
2
Center (front)
3
Right (front)
4
Left Surround (rear)
5
Right Surround (rear)
6
LFE
Hope that this helps. If you are Importing and placing "standard" discreet SS files onto AT's, use the first table. [I also rename each AT to reflect exactly what is going to be one it.] If you are Exporting, via SurCode to then plan on using table #2, when dealing with the discrete mono files.

How do I increase my sound using the Audio Mixer?

I needed to raise the volume of a clip I had in my Premiere Elements project. Somehow, I managed to do it. When I play the clip with the Audio Mixer open, I see the slider bar way at the top at a +3 which is great for the clip I have. I have another clip from the same event and I also need to raise the sound to a +3. I THOUGHT I had selected the clip, and then simply slid the bar up. I did this a few days ago. Now I am trying to raise the volume on another clip by sliding the bar up but it has no effect. I may have edited the start and end of the clip but I wouldn't think that would have any impact. I would think that any volume changes could be made to a trimmed clip. Anyone have any thoughts? Thanks.

Rick
Have you explored Normalizing the clips....Clip Menu/Audio Options/Audio Gain
Please see "Adjust the Input Level of Clips" in the following Adobe document
Adobe Premiere Elements Help | Mixing audio and adjusting volume
Are you working with Music Score Soundtracks?
Are you working with 5.1 channel audio?
Generalizing...you should be able to volume change an audio clip that has been trimmed.

6 channel audio device for STP

I need to do a temp dub on a small film and am going to attempt using STP 5.1. Can anyone recommend a 6 channel audio output device that is not expensive, yet will suffice for a simple mix.
Thanks for help!

Hey Muzak, I think you misunderstood Tony. He wants a multitrack interface to be able to monitor a surround mix.
Tony, here is a range of reasonably-priced interfaces--some Firewire, some PCI (which may or may not work in your Mac) <a href="http://www.musiciansfriend.com/rec/navigation/computer-hardware-recording -cards-audio-interfaces?N=1000013048914294967032&page=1"

Imported DV plays only left channel audio

In working with iMovie HD 6, I've imported video from my DV camera and I'm only getting sound from the left channel (I used a lapel mic plugged into the camera while I was recording). Is there a way to mix the left channel audio into stereo, or at least two channel mono so that my movie and subsequent DVD project will play sound in both channels? I'd prefer to run the fix within iMovie, but will consider exporting if necessary. I can't recreate the original interview without a lot of work.

Welcome to iMovie Discussions.
Yep, you can do it in GarageBand, just setting it to move the mono channel into both channels.
Or you could use the free, downloadable "Audacity", and just select the left channel, then copy it, and paste it into the empty right channel, like this.
However, to use the wonderful "Audacity", you've got to find your original audio in iMovie, then remove it from within its hidden storage, whereas GarageBand just "knows" where to find the audio if you send your movie there, so click on Share and then GarageBand, where you can select the Movie Sound track, and just turn the little 'panning' control, in the Mixer column, to the centre.

Audio Mix Problem

This has been driving me crazy for the last three hours and the deadline is end of day tomorrow. Here's what's happening:
I'm working with FCP 4.5 on a G5 Dual 2Ghz, OS 10.3.9. I finished editing a short 15 minute piece for a client. It consisted of some live footage of various places. The footage was all imported via a DV converter from VHS-C and Hi8 cameras. Audio was set to 48kHz There was a lot of editing to get the 2 hours of footage down to 15 minutes. As I was editing I was adjusting the audio volume of each clip so that the levels were similar from clip to clip. When playing back the timeline and watching the Audio Mixer window everything was fine. The faders would change as the playhead moved over each clip. Then we did a voice over. I made sure that the sample rate was set to 48k. That all went well. I then exported a mix for Soundtrack and created a music bed in Soundtrack. The Soundtrack project was set for 48k. I exported that mix and then imported the resulting .aif file into FCP. I added that to the timeline and that's where my problem began. The piece opens with some graphics for the first 30 seconds. The voiceover starts right away. When I play the timeline and look at the Audio Mixer everything looks fine. The voiceover channel (3) shows the audio level and the fader is at 0. The music bed channels (4/5) shows the levels and the fader is at zero (except for a brief bump up to +2 for a few seconds and then back to zero. And the audio for the video clips (channels 1/2) shows -inf on the fader and there is no signal, which is correct. Now when the playhead hits the 30 second mark and the audio from the video clips is supposed to enter; the channels for that audio never indicate any level, and the faders don't move from -inf. Also all of the other channel meters stop indicating the level. They just stop working. But the audio from the video clips is not even playing. I should be able to hear the on-scene audio when the video clips start. Even though all of the meters stop working the audio from the voiceover channel and the music bed do continue to play.
I looked through all of the appropriate settings and found the one for 'number of channels for live mixing' (or something similar) and it was set for 4. I thought that was going to solve everything, but unfortunately it didn't do anything. FWIW playback quality was set to 'low' on that same settings page.
Interestingly enough, if I just click in the timeline in random places while it is stopped, the faders will all move to what they are supposed to be set for at that point in time. However, if I play the timeline from that point there still won't be any audio levels indicated on the meters and the faders will not change as the timeline continues to play.
I can't think of anything else to try. I did reboot. I searched the archives here and didn't see anything similar to this problem. I'd really appreciate if someone could offer some suggestions. I hope I explained everything clearly enough.
Thanks,
Chris

Did the audio that won't play back now, playback
before you brought in the files from Soundtrack?
Yes, the audio tracks from the video clip played back fine before I brought in the Soundtrack music.
Is it possible you could have overwritten those
channels when you brought in the Soundtrack file?
No, because the Soundtrack music bed is on audio tracks 4/5 and the original audio from the video is on audio tracks 1/2. Also I can delete the Soundtrack file from the timeline and the audio on tracks 1/2 will play again and the meters and faders will respond properly.
If you load the problem clips in the viewer, do they
playback their sound?
I think they did, but I'm going to have to try again to be sure. I'm on another computer right now. I will do that within the hour and update this post.
Have you tried doing an audio mixdown?
rh
By mixdown, do you mean exporting the audio from the timeline? If so, I haven't done that because since I'm not hearing the audio from the video tracks I'm assuming it won't be in the mix when I export.
Thanks for helping out. I'm going to try a few more things and post back.
Regards,
Chris

Kmixer shows intermittently USB audio mixer(It works,too!)

I am perplexed by the sudden appearance of the USB audio mixer option.
It isn't always present in KMIX.
It has a PCM output volume control
It has an input option but no input shown.
Does anyone else have the USB Audio option in KDE?

I have found a use for the USB mixer in KDE.
If it stays loaded in KDE KMixer I'll be satisfied.
The trick is to enable XMMS with a .wav selection. Click on the O option on the left side of the XMMS display: select.....preferences.
Select Output Plug-in ALSA.....
Select ...Configure....
Select under AUDIO DEVICE ...USB Audio (hw1,0)
Select Mixer Card ...1 and PCM
Click OK
This provided stereo audio from .wav files on the usb Soundwave Optical 5.1 device connected to a USB port on my system while using XMMS. This device has a stereo output jack and an optical port.
At the same time, another .wav file was possible simultaneously( even the same .wav file) on the PCI audio channel from the normal KDE mixer and PCI card using other multimedia devices(kaboodle, noatun).
I do not have any device for 5.1 surround which is optically provided by the soundwave device(probably not properly addressed for it in the system anyhow).
Maybe this will help someone with their USB audio connect?

Premiere Pro Timeline with 3 video channels and 4 audio channels, audio channels change to 8 channels when clip dragged onto timeline.

Premiere Pro Timeline with 3 video channels and 4 audio channels, when clip dragged onto timeline audio channels change to 8 channels. Audio track mixer changes too. I edit undo to remove dragged clip and it reverts back to 4 channels of audio on timeline as does the audio mixer? Any ideas as to why the audio channels and mixer changes?

you can check the clip you are dragging to the timeline, if it has 8 tracks... can check by right clicking it in the project bin, choose modify, audio channels.
