FLME to stream multiple audio streams

Is it possible to stream multiple audio streams together with one video stream using FLME.
I need to create a live streaming application that should be available in many languages. My idea is to send 1 video stream + n * audio streams.
Any ideas are appreciated.

FMLE is not able to stream multiple audio tracks.
Perhaps a third party encoder is able to do, but the problem is I think the playback
cause adobe´s pluggin does also not support multiple audio tracks.

Home Theater need. Multiple Audio Streams from 1 card or possible to use 2 car

I currently have 2 SB Li've's installed and a SB Audigy in the box.
I would like to be able to send different audio out to different devices. I need to send audio from a game interface called MAME 32 to a speaker system connected to the PC. I also use this PC as a home theater PC and want to send audio from my DVD playing software out to my TV(in analog stereo mode) and/or to my receiver(in Dolby Digital mode using the digital connector).
I would like to be able to run these seperatly without having to go into the Control Panel and switch the default sound card like I am doing now. I do not need to run them at the same time.

Bummer. Are you guys working on something that might have this capability? Seems to me that the closer we integrate PC's into our entertainment systems the more need we will have for the ability to do multiple audio streams, i.e. MP3's to the living room. DVD movie audio to the family room, XM radio classical station to the kitchen for mom etc..
Intel is offering this as an onboard solution that has the ability to do at least 2 different streams.

Troubles with Multiple Audio Streams.[ca0106]

Hey everyone.
I have a few issues on my hands that i just cannot seem to get a strait foward answer.
First off, i have a Sound Blaster Live! 24bit pci sound card. Sound plays perfect as well as surround sound.
My issue is that i cannot get mulitiple things to play sound at once. All of the correct modules are loaded just fine and working well. I do believe that when i was using gentoo and could play multiple audio streams, i had alsa built into my kernel.... in arch i dont believe i do.
Im trying not to build my kernel all over again in arch because i think its something in arch i may be doing wrong...
Thanks
Anthony

Thanks for the reply.
I know for a fact im using ALSA. Since i made that post, ive been doing as much research as possible. I found on ubuntuforums, some dude posted some configs for his ca0106 sound card. I tried them and they take me to the same fork.
Surround Sound .... or .... Multiple audio streams.
So the big questions is, is it possible to have both? And would compiling a new kernel with ALSA and support for my card make a difference?
Thanks!

Multiple Audio Streams?

I'm wondering if there is an application that will allow the computer to route multiple audio streams out of my Mac Pro. or- if anyone knows how to create an easily switchable audio routing panel rather than going through preferences.
Eg. I'm playing Itunes (or hulu or netflix) through my audio line out through my Samsung TV thorough a speaker system to watch online content through the TV and I want to work on files on the computer at the same time, say edit video using FCP and routing that audio through USB speakers at the desk.
Being able to create multiple audio stream routing would be a HUGE asset for someone like me. Even if it's not possible, I would certainly love it if Apple would incorporate a quick switch selector in the pulldown menu for audio volume...
Thoughts? Anyone?
Thanks!

Thanks, the "auxillary effect" totally helped me stream itunes music to my iSight with soundflower....giving webcam streaming my system audio, which I couldnt do before without hearing anything....ugh so complicated! but this works!! Sometimes apple is so rediculous and I know there are more features they could build in.
Thanks!

Encoding multiple audio streams?

Can iDVD see and encode multiple audio streams for a single movie? Maybe this is asking too much but perhaps I've overlooked something...

The norm is to export video and audio out of Premiere Pro separately. Doing this, you will end up with one video file and multiple audio files. Bring them into Encore and add them to a timeline.

How do I import multiple audio tracks?

Hi there...
I have a number of video files that have multiple audio tracks in them. The problem is I can not work out how to get prem to see multiple audio tracks. The files import fine and I have also tried various other formates with multi-track audio.. but only audio "stream 1" is visible in prem.
What I was hoping is that the video would come in with a 2 audio tracks instead of 1 each in its own "lane".. so I can then use the mixer and the audio files are linked to the video file and in perfect sync.. (just like when you import with 1 track)
NOTE: I am not talking about channels.. but complete 2 completely different audio tracks.. and I know that I could extract these audio streams into wavs and then re-sync them but this seams overkill and a duplication of effort... surly there is a way to have prem support more than 1 audio track on a video file?
--Me

Well, if PP doesn't bring them in, then best guess is they just don't exist.
There's really no trick or user adjustment for this that I'm aware of. You import the file, PP sees what's in it. I've never observed or read about any other behavior than that.

Multiple Audio Lines

hi all,
Are there any open source projects out there that will show us ways to implement multiple audio lines and allow manipulation of each audio line seperately? e.g volume, pan etc??
Is anyone working on a project that they would post??
I have been working on a project which has 8 tracks, i have it playing the 8 tracks of audio but i am simply calling the same play function 8 times with a different file name each time. I use the play method described in the JavaAlmanac.
If anyone has a project in development or otherwise, i would be very grateful if they would be able to post it here!! I'm sure it will be of benefit to them aswell as everyone else.
cheers,
RC

hello again everyone,
As no one made any replys to this topic, i will now show you what i have ended up doing to create my multiple track audio sequencer.
Its not the best in terms of "smart code" but it works, and since i have a deadline for this project, i am happy to get it working no matter what way the code is structured.
i simply used this file
import java.awt.*;
import javax.sound.sampled.*;
import java.io.*;
public class AudioTrack0Handler
     boolean mute = false;
     String fileName;
     int loop;
     Clip clip;
     public void play(String file, int loops )
               fileName = file;
               loop = loops;
               try{
               System.out.println("Play method called file..." + fileName);
               AudioInputStream stream = AudioSystem.getAudioInputStream(new File("C:\\java\\code\\Audio\\" + fileName ));
               //AudioInputStream stream = AudioSystem.getAudioInputStream(new File("1.wav"));
               // At present, ALAW and ULAW encodings must be converted
               // to PCM_SIGNED before it can be played
               AudioFormat format = stream.getFormat();
               if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
                    format = new AudioFormat(
                              AudioFormat.Encoding.PCM_SIGNED,
                              format.getSampleRate(),
                              format.getSampleSizeInBits()*2,
                              format.getChannels(),
                              format.getFrameSize()*2,
                              format.getFrameRate(),
                              true);        // big endian
                    stream = AudioSystem.getAudioInputStream(format, stream);
               // Create the clip
               DataLine.Info info= new DataLine.Info(
                    Clip.class, stream.getFormat(), ((int)stream.getFrameLength()*format.getFrameSize()));
               clip = (Clip) AudioSystem.getLine(info);
               clip.open(stream);
               // Start playing
               clip.loop(loop);
               //clip.stop();
               } catch (IOException e) { e.printStackTrace();
               } catch (LineUnavailableException e) { e.printStackTrace();
               } catch (UnsupportedAudioFileException e) { e.printStackTrace();}
     public void stopAudio()
          clip.stop();
          clip.flush();
     public void muteAudio()
          /*Control[] ctrl = clip.getControls();
          for (int i=0; i < ctrl.length; i++)
               System.out.println(ctrl);
          FloatControl gainControl = (FloatControl)clip.getControl(FloatControl.Type.MASTER_GAIN);
          //double gain = .5D; // number between 0 and 1 (loudest)
          //float dB = (float)(Math.log(gain)/Math.log(10.0)*20.0);
          switch((int)gainControl.getValue())
                         case 0:
                         gainControl.setValue(-80);
                         break;
                         case -80:
                         gainControl.setValue(0);
                         break;
and created it eight times for 8 audio tracks. i call each track seperately when i need to access the methods. With the stop method and mute method, it also allows me to stop all tracks or mute/unmute individual ones during playback.
In parts This is a primitve way of doing it (i think) but it will remain here as a guide for anyone who finds it!

Any way to export QuickTime w/ multiple audio tracks?

I remember seeing QuickTime movies where on playback you can select which audio tracks to listen to. Kind of like director's commentary or different language versions for the same video stream...
Is there a how-to guide for making a movie like this in FCP? We have one video file and multiple audio files that we've placed in different tracks in the timeline but when we export to a QuickTime movie they get all merged together. We tried setting it up with multiple audio channels and then control-clicking to get that menu with each audio track and putting them into the different channels, but there must be something we're missing...
Is this something only FCP 6 can do? I think we have version 5.
thanks!

I'm a little rusty on this - and without access to FCP 5 at the immediate moment - but I think the key is to set your sequence to have multiple (as in more than 2) audio outputs, then select Channel-Grouped for audio during the Export via QT Conversion.
If that doesn't work, you could always paste additional audio tracks onto your movie in QT Pro. After all, you'll need to tweak your language settings for audio track in QT Pro.
But where have you seen this implemented to do a Director's commentary-type option? I've read that multiple (discrete) audio tracks work only if they're tagged as different languages and the user's playback system is setup for one of those languages. (But I've been wrong before...)
And welcome to the forums.

Mixing multiple audio files using Windows Azure Media Services

Hi,
I'm trying to "mix" multiple audio files on the server, e.g. I have 4 different .wav files for each instrument in my song: vocals, guitar, drums, bass. I want to create a new stereo "mix" from these, but I want to change the relative
volume of one of the tracks, say vocals, or mute it altogether. I can use libraries such as NAudio to achieve this, but I'm wondering if Windows Media Services can do this, and if so, can it do it dynamically, i.e. create a live stereo stream and allow
me to add/drop individual tracks on-the-fly. I've been looking through documentation on Azure Media Services and Expression Encoder, but haven't found the answer.
Thanks,
Alan

Hi Georgios,
There is support for using audio overlays in our service - see http://azure.microsoft.com/blog/2014/08/21/advanced-encoding-features-in-azure-media-encoder/ for examples. It may be possible to perform pairwise overlays to implement your scenario.
However, it's currently not possible for us to integrate customer-built processor code into our service.
Cheers,

How to edit a multiple audio video clip on Premiere

Hello everybody
Maybe this is a dumb question, I'm sorry if I'm asking what is obvious for you, but I swear I tried to find on the web and on this forum, but I couldn't find anything.
Well, I made a video using a screen capture software called Dxtory, that provides me the ability to record my PC screen, with multiple audio tracks.
Ok, now I have a 15gb avi file. When I open this file in the Media Player Classic, I can play one or both channels. The first channel is the original audio captured from my PC. Every audio generated by my PC is in this track. The second track is my voice, with my commentaries. I have all of this in one single file. They are not splited. It's just one file.
Then when I import into Premiere, the software just recognize the video track and the first audio track. I can't find the second, with my voice.
I know I can split the clip into 3 files (1 video and 2 audios) but it would take longer. I just want to drop the file on Premiere and edit the audio volumes quickly, because when I talk I would like to low the volume of the PC audio.
Now, the question: Is there a way to Premiere recognize both tracks in this single file? How?
Thanks in advance for any help.

I'm actually surprised that Pr can import this at all--the video is Xvid. Maybe it's some variant that Pr's importers can handle, as Jeff suggested. I dunno--it doesn't play well for me, regardless, and I'm not going to install the Dxtory codec to find out.
Anyway, to the matter at hand: while AVIs can, apparently, contain multiple audio tracks, Pr's importers are limited to a single track. However, Pr has other importers than can handle multiple audio tracks. QuickTime--which is a wholly different process--supports multiple audio tracks, as does MXF (some flavors). However, Xvid in QuickTime (which is feasible) won't import in Pr (at least on a PC), and Xvid won't go into an MXF file at all; that means you'd have to transcode. Personally, this would be my choice--but I found that the original clip played back pretty terribly, so that would be why I'd go that route.
Additionally, you could extract the second audio track to a separate WAV file, import both the AVI and WAV, and then use the Merge Clips feature to marry them together as one pseudo-clip. Not perfect, but it would work. The benefit is that you don't re-encode anything.
So, I've got solutions for both the re-encode/MXF option (my preference) and the AVI/WAV option. Here's proof of the MXF (transcoded video to XDCAMHD422 50Mbps) with four audio channels (stereo must be split to dual mono):
At the end of the day, these (or a variation of them) are your only options. Pr simply won't import multiple audio tracks (even dual mono) in an AVI container. Let me know if you're interested in either of the solutions.

Can you copy multiple audio (text to speech) files from one slide onto a new slide at once?

Can you copy multiple audio (text to speech) files from one slide onto a new slide at once? OR do you have to copy and paste each line of text to speech and insert into new slide?

Hi there
I believe that you end up with a single file that you can use. Once you get that created, it's an audio file in the library. You may then add the audio file to another slide or object by looking in the Library after choosing to add audio.
Cheers... Rick

Is it possible to retain multiple audio tracks when exporting?

While ripping my DVD collection, I've wanted to add a purchased RiffTrax (see www.riftrax.com) to the movie as another audio track. I've been successful, but it took the following steps:
1. Encode the movie using Handbrake, open the resulting m4v file in Quicktime Pro
2. Also in Quicktime Pro, open the Rifftrax aac file I created and add it as another audio track in the m4v
3. Save the m4v as a Quicktime mov file
4. Use Handbrake again to encode the mov file into an m4v file, including my added audio track
The reason I have to do step 4 is because if I were to export an m4v file directly from Quicktime Pro, it would compress all of the audio tracks into a single audio track. It would save a lot of time if Quicktime could export multiple audio tracks, at least when exporting to formats that can handle them. Does anyone know if this is possible?
BTW, if anyone wants more details into how I create the RiffTrax aac, just ask.
- Jake

I've answered my own question, it was a lot easier than I thought. After the first encoding by Handbrake, there's really no difference between calling it a mov file or m4v file. I can change the file extension at will and there's no need to do an export that mashes the audio tracks. It's only AppleTV that needs to see the m4v file extension, Quicktime and iTunes doesn't seem to care one way or the other.
Thanks for letting me think out loud.
Jake

Editing Multiple Audio Clips From Premiere in Audition

Hi there,
I am working with video/audio in Premiere that has frequent cuts (although the audio is derived from two files) and I need to edit all the audio files at once, rather than one by one, in Audition. I was hoping to this by nesting the audio in Premiere but I am not able to edit the nested file in Audition after this.
If anyone has any ideas of how to work with and apply the same properties to multiple audio clips from Premiere in Audition I would greatly appreciate it.
Thanks...

Hi everyone, I also have a trouble with cs6. I just record 3 tracks in the early today, then when I got home, I saved as sexs file ( wrong decision). After that, I went back and try to open the file, it can't file the recording tracks. The only one thing still exist is my beat, what should I do to recovered it? thanks for helping me out of this.

HT201066 How can I split a long recording audio file into multiple audio files?

Hi,
How can I split a long recording audio file into multiple audio files?
With Windows I was using Nero software, which is not available for Mac. Is there any similar app for free for Mac?
Thanks!

Hello ingiorgio
You can import the track into GarageBand and then split the tracks there. Once that it is done you can highlight the ruler section and then share the song to iTunes to get them separated out.

How to play multiple audio tracks simultaneously?

Hi there,
I am having problem with playing multiple audio tracks. I want to play 2 or more audio tracks at exact time (without delay) - is it possible? how can it be done?

So, essentially, you're trying to take a recording of say, a singer and a guitar player, and end up with the singer in one file and the guitar in the other. Got it.
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/Merge.html]
That sample will merge multiple input files into a single file. Because you want to play the files together rather than save them, just take the sample and strip out all of the DataSink stuff, and add the following line right after the Processor "outputProcessor" is realized...
outputProcessor.setContentDescriptor(null);
So, it'll make the following revision to the code:
     // Create the output processor
     ProcessorModel outputPM = new MyPMOut(merger);
     try {
         outputProcessor = Manager.createRealizedProcessor(outputPM);
                    outputProcessor.setContentDescriptor(null);
         outputDataSource = outputProcessor.getDataOutput();
     } catch (Exception exc) {
         System.err.println("Failed to create output processor: " + exc);
         System.exit(-1);
     }That'll make the outputProcessor play the file, as if it was a Player object. You won't have any visual controls, but if you need visual controls, then don't do that, and just create a Player object to play the outputDataSource.
