Surround Sound/multi-channel audio out

My brother has a set of 5.1 "surround sound" logitech computer speakers that we hoped to plug into the mac... but they seem to require 3 jacks... not the single (2 channel) jack out that the powerbook offers.
Anyone have a workaround?

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.

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?)

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 outputs from a laptop such as 5.1 or 7.1

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? How ? (Dolby Digital, PCM etc.)

So,
Take 2 now support 5.1 channels audio out, at least for some HD rentals.
I am wondering if anyone has gotten that to work.
I have Apple TV connected via HDMI to my receiver (which can decode both the bitstream as well as linear PCM for multi-channel tracks).
However, I don't seem to get any multichannel, and the Dolby Digital toggle in Apple tunes makes no difference.
Has anyone gotten 5.1 to work, and if so, which which movie/tv show/trailer?
Thanks,
Dan

1. Not a great fan of detaching audio except in multicam clips. Generally I'd suggest using the expand audio components function to access the channels.
2. Yes. Switch off the auto tracks in the browser and only turn them back on for the clips you need in the project. With expanded audio components, if you turn the channels back on they will reappear in the timeline.
3. You use roles for this. I know time is tight for news, but taking a few moments to assign roles to the clips in the borwser, which you can do in globally, will allow you to export with separate tracks.

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?

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.

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.

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.

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

Multi channel audio not exporting from fcpx xml as mono to logic always comes in a mixed surround

I have a long edit cut with 24 bit multi channel wav files (i.e 6 microphones on separate tracks but in a single wav file.)
This is very a very common production practice.
when i import into fcpx it defaults to seeing the files as surround. I change this to mono so i can mix and spit the audio between each mic.
The last step in the edit is to hand the mix off to the sound designer in logic.
however no matter how i export the xml file for logic. it always comes in as a surround file again instead of mixed mono files.
it shows up in logic as 6 tracks but all but generally only the top track has a mono mix of all 6 and the rest are blank.
it shows that all 6 are seen as 5.1 surround indicated by the icon.
interestingly if i just import the file directly into logic it comes in as 6 mono files. (the icon for mono showing and all are separate microphones)
Any ideas on how to get fcpx not to export the audio xml as surround? (it seems that it is locked to that on import no matter how i modify after)

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.

How do I create surround sound 5.1 audio in Premiere Elements 10?

Okay, that's my question.
I have a Zoom H2n which captures two stereo channels from its 5 microphones and it creates a pair of stereo audio files. I would like to import them into Premiere Elements 10 on my Mac (OS X Lion on a desktop Mac), create a video and export the video and audio to a DVD with surround sound.
Is this possible? I have a 5.1 video camera, and the sound from that is exported correctly to DVD, so I know Premiere Elements handles existing 5.1 sound correctly.

> please report your success
Confident, aren't we? :->
Audacity would import the sound from the .mts files that my Canon saves video and surround sound to, but Audacity couldn't play the sound. It was there in the waveforms, but just a click came out. C'est la vie. I just went directly to my H2n files, and it works fine with them.
I shoot a video using a regular mic, and I also record the sound externally to my Zoom H2n. I use a finger snap or clap as my clapper board. I have the H2n set to 4 Channel, which means it records two stereo audio streams, one with a name ending in MS.WAV, and the other ending XY.WAV. I use the MS stream as my front, and the XY as the surround. I also make sure the H2n is recording at 48000.
I copy the two .WAV files to my Mac. I copy the video to my Mac.
The current version of Audacity is 1.3.14, which I used. Other versions may vary in how to set them up. You'll need current versions of LAME and FFmpeg, and Audacity directs you to the correct locations to download and install them, if you need to. Then you follow the directions to tell Audacity where to find the files; when all is correct, Audacity displays the version numbers instead of asking you where they are.
In the OS X version of Audacity, go to File -> Import -> Audio ... and locate the MS and XY files. Select them both by command clicking them, then select Open. I get two warning dialogue boxes about working on original files, so I work on copies, click OK both times. Audacity then shows its main window with two files, each having 2 tracks of audio. I do no processing in Audacity, but you may choose to if you wish.
I select File -> Export and in the resulting dialogue box I choose as my format AC3 files (FFmpeg). Choose a file name in the Save As box, then click Save.
Now is the hard part. I get a window for Advanced Mixing Options. Because I have four streams of sound, the window defaults to four channels. However, I need six channels, so I slide the slider over to get the six. For my Mac and Audacity versions,
   Channel 1 is left front
   Channel 2 is right front
   Channel 3 is center
   Channel 4 is low frequency effects (LFE)
   Channel 5 is left surround
   Channel 6 is right surround
By clicking the boxes you connect or disconnect MS left to Channel 1, MS right to Channel 2, XY left to Channel 5, and XY right to Channel 6. Then I click to OK button, and Audacity writes the .ac3 file with the name I gave it.
Start up Adobe Premiere Elements; I'm using 10, and I use the timeline. I import the video file and the .ac3 file. I double-click the video and shorten it to the first useable snap. Then I double click the .ac3 file and do the same.
I drag the video to the timeline and play it just o make sure it's where I want it and to watch the waveforms from the audio portion. Then I drag the audio to the narration track and sync its snap to the snap on the video's soundtrack. If I remembered to record at 48000, all is in perfect sync.
Right-click the video and select Unlink video and audio. Then select only the audio track that is with the video and delete it. Then select the video and .ac3 tracks and link them. Export to DVD, and I get a 4-channel surround sound with the video.
I understand from Audacity forums that the assignments of the various channels to left, right, center, and LFE have changed between versions. Be aware the assignments may not be correctly reported here and that they may change with later versions of Audacity.
Audacity is free, and so are LAME and FFmpeg. Audacity lives here: http://audacity.sourceforge.net/ and its wiki is here: http://wiki.audacityteam.org/wiki/Audacity_Wiki_Home_Page

Multi-Channel Audio to USB converter

We have an old windows pc with an awesome Altec Lansing ADA995 audio system, and I was wondering if it was possible to hook this system up to our new Macbook Pro with a converter to USB or the like.
I don't know much about audio hardware, but the audio inputs into our old system were yellow green and black if that helps. Thank you!

wow wasn't that speaker system branded by Dell? A friend of mine had them and I remember setting them up for him - those things were LOUD! The volume at like 10% was loud enough to be heard thought the house - and isn't this the model that doesn't even have a volume knob? (other then the bass volume knob on the back of the sub) I think you had to have a special sound card correct? SantaCruz or something like that?
Anyways, I think you need one of these:

How to get Surround Sound 7.1 output out of all speakers?

Hi all... I moved my system from Ubuntu recently and am having one small issue that I haven't been able to solve; everything else is working great and I'm about ready to move all of my other systems to Arch also, once I've solved this. :-)
The one nagging issue I'm having is with sound. This is a fiber digital connection that was working on the ubuntu install and a couple other distros I play with, but I haven't been able to find the issue in Arch. Sound comes out of only the front-left and front-right speakers. When I do the sound test, it lists all of the other 7.1 speakers, but no sound out of anything other than the front 2 speakers. I noticed that I don't have an asound.conf, so I was wondering if that might help or if it's not needed with Arch?
sound.conf contains the following:
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
/proc/asound/cards contains:
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf9cf4000 irq 22
arecord -L shows:

Discard all samples (playback) or generate zero samples (capture)
If anyone has any pointers, it would really be appreciated. I'm begging for help. ;-)

Thanks! :LOL: - those were 2 of the url's I've been looking through (in addition to the alsa faq, some stuff on the ubuntu, gentoo and xbmc forums).
I've setup an asound.conf and am about to give that a test.
--edit--
Well, that didn't solve it. I'll have to keep trying. :-(
If anyone has managed to get surround sound working out of more than just the front 2 speakers, I'd love to hear how you did it. ;-)
Mine is connected via digital, so it's beginning to look like I need to set spdif up somehow.
But... Now that I think about it, it 'should' be pretty easy since all I basically need is for it to force all raw audio out the fiber digital connection since the receiver actually handles all of the decoding (dang....it worked great in Ubuntu, now if I can just figure it out in Arch). LOL
Thanks!!
