Surround/Multi-channel output

Is there any way to use the Java Sound API (without any extensions/plugings etc) to play audio on a surround-system (e.g., a 5.1 capable soundcard)? If not, are there any Java API that provides this feature?

You can play a sound in a surround-system. However, Java Sound API has some restrictions.
1, It does not play multi-channel format.
2, It does not support speaker channel assignment. That means you can not choose a certain speaker channel to play.
So overall, it can play a sound format which is either one or two channels in a multi-channel system.

Multi-Channel output audio from Quick Time (or iTunes)

Hello all,
I am trying to get multi-channel AC3 audio output from QT and can only get two channel stereo. I have seen lots of related posts but can't quite get it.
I am trying to configure a Mac Mini to output properly via the TOS link port to my audio system. I get surround sound fine playing a DVD but not when playing a .m4v file that does give me surround sound when played on my Apple TV.
Should this be possible?

I appreciate the link Brent! I also had someone point me here http://fplanque.com/dev/mac/ac3-ac-3-5-1-surrond-sound-apple-mac-osx and all is good now.
Thanks!

Multi Channel Delivery

Hi All Experts,
We are trying to evaluvate Oracle Documaker 12.0 and were sucessfull in most of the part.
One question remains unsolved.
Does Oracle Documaker (12.0) support multi channel delivery? One of the customers require output to be in the format of PDF, Print, Email ( until this it seems ok), SMS, Voice ( which we are not sure of).
Can any one give some guidance of getting the output format set to SMS or Voice?
Also, how to acheive Multi Channel output based on a value in the input extract file? ( Using multiple FSIUSER.INI??)
Thanks
Arumugam

Hi Arumugam,
I am assuming you are actually inquiring about Oracle Documaker Enterprise v12.0.1.
If so, there is a Reference Implementation Master Resource Library (RI-MRL) that comes out of the installer and is referenced in the Documaker Enterprise Installation Guide, with examples for the different Distribution types and settings including example XML inputs that trigger batches for SMS and others.
Input controlled output distribution is done via the batching configuration in the Administrator and data mapped to the database tables in the schema. Recipients are selected based on the batch configuration, via the Selection Criteria Rule, which allows you to use any metadata from the input that is mapped to be distributed to one or more batches. The Batch configuration defines the output and distribution options, see "Including Recipients in a Batch" section of the Administrators Guide documentation.
If you review the Documaker Enterprise Administration Guide for SMS references you will find a section entitled Setting the Distribution Options. There is out-of-the-box SMS support through SMTP-SMS bridge (see UseEmailForSMS in the Administrator Guide) where you provide the email address in the input stream for the SMS message delivery. If you want full fledged SMS and Voice message support directly via phone numbers through the various wireless carriers I recommend you review offerings such as Oracle User Messaging Serivice (UMS) (e.g. http://docs.oracle.com/cd/E14571_01/integration.1111/e10224/ns_intro.htm) . Documaker Enterprise has a built in integration with UMS services (see UseSMSService in the Administrator Guide) but also has integration points to allow for other integration so if there is a messaging service that your customer(s) prefer or own the Output Publisher component offers extensibility to map user classes to mime types (user defined or standard) to push out data to the desired endpoint.
Regards.

Exporting multi-channel H264 file

We have been mastering projects using H264 for years and need to export a multichannel version (3 discreet stereo tracks for vox, music, and SFX). Can we do this with H264? I understand this is possible using Quicktime and have done this successfully, but as we all know, exporting Quicktime using H264 as your codec is not the same as using H264 (the quality difference is unacceptable). Are there any workarounds? I can only think to export the video (h264) and audio (Quicktime audio only) assets separately and send them as discrete files but was hoping they could somehow be combined.
Thanks for you input.

Also, I am not using a multi-channel output, only built-in output (stereo). Still, does not seem to work.
Another test -- opened file in Soundtrack Pro. I see the four channels, though they are grouped in some way that I cannot separate at present. I save the file as aiff, and this time Logic will open it, though it seems somehow corrupted, won't play.

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.

No multi-channel available with HDMI output in Audio MIDI Setup on Macbook Air mid-2011 !!!!!!!

Hi everybody !
I am currently facing some problem with seting up a surround sound system.
I looked everywhere on the web but i couldn't find any proper answer to this problem.
To sum up, i want to have a Dolby Digital or DTS surround sound when i'm playing a movie (with an AC3 audio track obviously).
I have a Macbook Air 13" Core i7 connected to a SAMSUNG Plasma TV via an iWires thunderbolt -> HDMI cable (bought on the same time as the MBA). This TV is connected to an amp via an optical cable and this amp to a 5.1 system.
When i am going to Audio MIDI Setup to configure the HDMI output, i cannot select any multi-channel option, only stereo !!!!
Is someone has any idea how to solve this problem ? I am struggling a lot and spent hours on that without finding any solutions !
Thanks a lot for your time !

Hello ckkzzzle,
I was looking into the issue you are describing and think I have a great article to help troubleshoot it. The article is called Apple computers: Troubleshooting issues with video on internal or external displays found here: http://support.apple.com/kb/ht1573.
Start here, and work your way down as needed:
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
If more than one video adapter is in use—or "daisy-chained"—troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
All the very best,
Sterling

How to building a multi-channels analog output task in visual c++ 6.0 (without Measurement Studio)?

Hello!
I have a PCI 6251 card, and using DAQmx C function to generate a wavwform. (single channel ).
But, how to creating a multi-channels analog output task, and had a different frequence in each channels?
Thanks.

This is getting to be a common question!
The answer is, you can't.
If the rates have common factors, you can use a higher overall rate. The slower waveform will simply have extra points in it to make up for the higher update rate.

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 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.

Multi-channel audio play

I want to play one or more simultaneous sources to each of several stereo outputs.
So either a multi-channel soundcard (eg 5.1, 7.1) or several cards, or even several multi-channel cards.
As far as I understand it the multi-channel cards are made up of several stereo channels (main, surround, centre etc).
I want to play different sound files (or even several files simultaneously) on EACH of these stereo outputs.
Just to prove that I am completely crazy, the reasoning behind this lunatic requirement is that the loudspeakers are all mounted under a model railway layout, and are to be used to create ambiance.
Clearly I cannot use the Java Sound Engine mixer as that can only drive the primary output.
I have searched several code examples on sun, and on jsresources but cannot find anything that uses m ultiple simultaneous outputs.
Can anyone point me at any useful starting point.
Many thanks,
Howard Amos

You are looking to do SPDIF passthrough.........
If you have that option in your DVD software you need to be sure you are passing the signal through untouched. There is a post of how to do this on the shark007.net forum,
http://shark007.net/forum/Thread-problem-spdif-passthrough-x-fi-decoder-Win7
and make sure that in PowerDVD or WinDVD or whatever player you are using, that SPDIF passthrough is selected. If you have Dolby digital or DTSConnect enabled you are sending a signal and encoding it, when your receiver is the device that wants to decode it.

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?)

Can PCM multi-channel wav (not DD or DTS) be sent over SPDIF

<Can PCM multi-channel wav (not DD or DTS) be sent over SPDIF? --- X-Fi Elite Pro SB055A and Audio Creation Mode ---
If I understand correctly, SPDIF format can support uncompressed MULTICHANNEL wav format (within the limitations of its bandwidth) as well as the more usual DD or DTS encoded format on SPDIF.
One of the neat things about Creative's Audio Creation Mode in the Recorder section is the ability to actually record to a multi-wav format (but the sample size seems to be fixed at 24 bit). This means it is quite simple to have several mixer inputs and record a mixed multi-channel wav file in one go. Great and this works as expected with a 5. ?24 bit/48 kHz recorded test file.
My question is when one plays this recorded multi-channel wav file back, the mixer monitor (playback) shows the various 5. (say) channels with their separate content. Can this multi-channel *uncompressed* wav data? be sent over the SPDIF output as is to preserve the PCM quality? (so no DD or DTS encoding used)? I have tried this and I?ONLY seem to be able to get a STEREO (2 channel mixed down) version received at another SPDIF-in sound card (my Audigy 2ZS PCMCIA). I tried almost all selections at both ends involving SPDIF.

@? In answer to my own question, and I think I had known this a while back, SPDIF standard only supports transmission of either 2 channel PCM (uncompressed) stereo with up to 24 bit resolution per channel and up to as much as 92 kHz sampling frequency, or compressed (DD or DTS) multichannel audio up to 5..
Since each frame of SPDF is 64 bits in length (with a single sample of L and R channels plus extra bits of status in each frame), at 92 kHz max sampling rate, this translates to about 3 Mbits/sec bit rate. However most SPDF don't support the 92 kHz rate (which for 24 bit would be the stereo rate for DVD-Audio) for various copyright protection reasons.
Here is short demonstration of SPDIF transmission of 24bit/96 kHz between two sound cards with and without "bit accurate for playback" enabled:

Multi-Channel (more than stereo) Audio Editing

Hi, is there a way of setting Audition, to when opening multi-channel WAVs, to open them all in one display?
Currently, if you open a stereo WAV, you get both channels visible so you can edit both channels as one.
However, if you open a 5.1 WAV, you get six separate mono WAV files listed.
This is a bit of a serious challenge to me as I'm trying to edit some surround SFX!

I'm afraid that currently, Audition is two channels per track max. I have no idea whether this will change in the future - a lot of other DAWs these days can certainly cope with more than two channels per track - I think Reaper does, for instance.
