Fix For Missing Multi-Channel Audio in Video Files

Download newest version of Handbrake, re-encode your files using the Preset settings for AppleTV 2. Once the file is done, it will play with the audio. I tested it on a movie earlier. Hope this works for all of you, I have been just as frustrated since the 4.3 update was released.

My actionscript is below, if that helps anyone. I don't know
if this is a stupid question with an obvious answer, if so please
let me know:-)

Wanted: Multi-Channel Audio Interface for iMac & GB (USB)

I am looking for an affordable multi-channel audio interface for my iMac for use with Garageband. My goal is to playback old songs from my old computer (Atari ST) through my Yamaha gear and record the audio into GB so I can mix it. (READ: Not interested in transferring MIDI.)
My goal is to get at least 4 and ideally 6 channel/track recording in GB. I’m not sure if the multi-channel units I see, such as the Alesis MultiMix 4 or the Behringer Xenyx Q802USB send all channels to the Mac or if they mix it down to two channels first.
I’d prefer to mix all the channels in GB rather than pre-mix it. Also, I’d prefer to have 1/4” jacks; XLR would be a nice bonus. USB; since Firewire is going away and Thunderbolt is too new.
Any suggestions? I’m trying to keep this under $100. (Also, I know I can use multiple low-budget devices and aggregate them in Audio/Midi, but I do NOT want to go that route.)
Thanks.

As you imply, keeping it below $100 makes it tough.
Generally only the two channel interfaces are close to $100.

No multi-channel audio from DVD Player or Quicktime?

I have the A52Codec 1.7.6 installed. The codec preferences are set to output multi-channel audio. I have my Audio MIDI setup speaker configuration setup for multi-channel audio and the speaker assignment tests are all perfect. VLC plays back files with AC-3 soundtracks in perfect 5.1 multi-channel sound. Final Cut plays multi-channel audio properly as well.
When I watch a DVD, it is decoded to stereo. The dialog on 5.1 always comes from the left and right speakers and never from the center channel. It doesn't matter whether I remove the A52Codec and try again the result is aways the same, 5.1 audio in Quicktime and DVD Payer gets decoded to stereo. It is not that extra channels are missing, if that were true I'd get no dialog at all.
What do I have to do to make the DVD and Quicktime multi-channel audio decode as multi-channel audio and not stereo.

I'm not sure if this will resolve your issue or not, but have you configured it using /Utilities/Audi MIDI Setup ?

Multi channel audio outputs from a laptop such as 5.1 or 7.1

is it possible to get multi channel audio outputs from a laptop such as 5.1 or 7.1 for watching Movies or television while using Windows media Center.

Ok so i order to help anyone who is interested.
The only ironic solution to this problem i found was to use a plugin called xto7 to convert the xml to the old fcp7 format.
i then imported this into premiere pro.
this was then able to export an OMF that when imported into logic 10 that was using the correct 6ch mono setting as separate tracks.
Insane but it works until Apple fixes the incorrect meta data import in FCPX that sets the xml export to the default import that is always surround.
this is the only way i was able to send stems with all the edit points and fades for the sound editor.
If you don't have premiere lying around you maybe able to do it with fcp7 too we just didn't have it in this studio.
Fingers crossed Apple fixes the fcpx xml export.

AAC and multi-channel audio

Can AAC be used to encode multi-channel audio, such as DTS-HD Master Audio?
DTS-HD Master Audio is an optional audio format in Blu-Ray. It uses lossless compression.
There are other audio formats from Dolby Digital, for example, that are used to encode HD audio in Blu-Ray. Can AAC be used to encode those as well, without any loss of information?
Is there any work in progress to make HD audio such as DTS-HD Master Audio available discretely on disc, like what the older DVD-Audio format made possible for 5.1 channel surround sound on disc?
Thanks.

What adjustments do you want to make?

Multi Channel Audio Instrument [Kontakt 2]: Auxes not working?

Hi,
I've searched the forums and come up with several posts about using multi-channel audio instruments, but none seems to exactly address the issue I'm seeing (and being confused by). I'm trying to set up Native Instruments' Kontact 2 sampler in multi-channel mode in Logic Pro 7. I perform the following steps:
1. On an available audio instrument object, I click the input drop-down, select Multi Channel -> AU Instruments -> Native Instruments -> Kontakt 2.
2. When Kontakt 2 opens, I load, say, three different instruments.
3. In Kontakt 2's Outpus area, I create three outputs, labelled "st. 1", "st. 2", "st. 3". I cable these to "Plugin Output 1" and "Plugin Output 2" for st.1, "Plugin Output 3" and "Plugin Output 4" for st.2, "Plugin Output 5" and "Plugin Output 6" for st.3.
4. In Kontakt 2, I assign the output of instrument 1 to st. 1, the output of instrument 2 to st. 2 and the output of instrument 3 to st. 3.
5. Back in Logic Pro, I create two new (stereo) audio objects and assign them to channels Aux 1 and Aux 2 (and name them accordingly).
6. In my Aux1 object, I select its input drop-down and choose Instrument1 -> Kontakt2 3 & 4.
7. In my Aux2 object, I select its input drop-down and choose Instrument1 -> Kontakt2 5 & 6.
Okay, so basically I'm set up now, right? So to test this out, I set the MIDI receive channel of all of my instruments in Kontakt 2 to omni and click on the built-in keyboard in Kontakt 2. I can see the volume level indicators on all three instruments light up. I can also hear all three instruments coming out of my speakers. However, when I look at the environment page where I've created these objects, I find that they're all coming as a stereo sum from the original audio instrument object. The Aux1 and Aux2 objects are just sitting there doing nothing.
What gives?
Dual 1GHz PowerMac G4 (Quicksilver) Mac OS X (10.3.9) MOTU 828

Okay, I found the solution to this, and it's odd enough that I figured that I'd post it just in case anyone else ran into it.
It turns out that the multi-channel thing does not work at all when you play Kontakt 2 from the built-in keyboard (in K2). Visually, K2 still shows all the audio going out on the corresponding channels, etc., but I guess it's summing it and outputting in stereo only when you do that. If you send it data from Logic, it works just fine. So I had this setup correctly all along.

Multi Channel Audio Setup

I've been trying to follow various tutorials for setting up multi channel audio insruments and I always get stuck at the point where you select Output 3-4, 5-6 etc. from the Aux 1, 2. 3 etc. objects. I never have more than Output 1-2 to choose from. I usually use the built- in audio or sometimes a Lexicon Omega. Do I need another interface to accomplish this or am I doing something wrong. I've accomplished quite a lot of things with Logic, but this has been hanging me up for a year now. Any thoughts?
Thanks,
Tom

multi channel audio instrument doesn't require a special card or interface
any interface with stereo output should work
you need to make sure your audio instrument supports multi channel
logic pro only has Ultrabeat and EXS24 as multi channel
under the plug-ins choose multi channel instead of stereo or mono then choose what ever is under multi channel
example BFD, RMX, KORG LEGACY and other 3rd parties that support Multi

This is a very simple question about multi-channel audio playback

I have an mp4 file that i made and i made it 7.1 surround sound, and i'm pretty sure that this 7.1 surround sound works, as it can be played in VLC. i'm using netstream to load my files now. How do i make it so that flash can playback all 8-channels of sound? I suppose kglad would know the answer

Flash doesn't support multi-channel audio (yet?)

Multi channel audio output

i am trying to output a wav file from a avi file.
this file has multi channel audio, in this case 4 channels, though when outputting the audio by
After Effets, mono or stereo is the only available choice.
In this case, which channel will be extracted from the avi file?

I'm 99% sure that only the first 2 channels will be imported. I've seen some weirdness where multichannel audio has been bounced to a stereo pair on import causing a jump in levels. Your best bet is to use Soundbooth (or Premiere) or an audio/editing app to do the conversion.

Multi-channel audio mapping and adjusting.

Hello All,
I am trying to understand the concept of multi-channel audio and the way premiere handles the files.
I have an MXF file which contains 4 channels of audio. I am able to get premiere to view all 4 channels with an adaptive track, however, how do I make adjustments to each track?
EX: Say I want to adjust one of the channels within that adaptive track, how would I do that.
Former FCP user thanks you.

How to combine discrete audio and video files?

I am working on a project which requires me to merge a video file with a PCM audio file from another source.
I just bought Compressor 4.1.1, expecting to be able to do exactly this.
The only "multiple input - single output" option I can see is creating a surround sound group, adding my audio as left and right channels, and then attaching the video.
This does not work. Pressing "add" at the end of the process does not result in a new job.
Help please!
G.

QT7 Pro is able to do this. Cost is $30.
In QT7 Pro, open up the audio and video files to be matched.
Select all the audio and then select copy
In the video window, put the playback head where you want the audio to start then select add to movie.
Verify the playback is as desired, then save the movie. Done.
Takes longer to describe the process than to do it.

Of course, life is good when the in point is exactly the same for both audio and video ...
