Record multiple audio streams

Hello
I'd like to make a voice chat software that can record all
audio streams in one flv file. Is it possible with FMS 2?
Thank you for the answers:
Peter

Hello Peter,
Using the server NetStream object, create a new server stream
and give it a name, e.g. master:
ns = Stream.get("master");
Then start it recording with the instruction to append all
the new recordings:
ns.record("append");
Then call the play method of the NetStream with each new
publishing stream and a second parm of -1 to indicate live
recording:
ns.play("pubstream1",-1);
ns.play("pubstream2",-1);
When you want to stop recording call:
ns.play(false);
These are the basics. Post back if you need more.

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!

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.

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.

Synchronization of Multiple Audio Streams

Hi,
I'm trying to synchronize several Audio streams during
playback and recording. Several questions I have and not sure if
actually feasible or how to best address :
1/ When playing back 2 audio streams, how can I ensure the
playback is full synchronized (<20ms difference) when client
receives the 2 streams in playback ? Basically trying to simulate a
mix-down with 2 // streaming. Ultimately wants to achieve this with
about 5 audio streams playing back and can't accept tolerate delay.
I suspect I need to synchronize the start of each stream so that
they all start together, but not been very succesfull so far.
Alternatively is there a way to mix-down 2 streams on server and
send back a 1 mixed-down audio stream ?
2/ More tricky I believe : If I playback 1 audio stream and
start recording a separate audio stream, I'm getting again
desynchronised. Later If I replay the 1 audio and the newly
recorded one, both are not anymore aligned. I suspect (but not sure
that the delay and desynchronization is introduced during the
recording but not sure and reason I asked first question...
If someone knows those answers or could provide some
direction of work.... I would greatly appreciate.
Thanks

When it comes to FMS streams, there really is no way of
accurately syncronizing streams. Since you can't keep data in
buffer when pausing the stream, and you have to rebuffer any time
you seek, it's impossible.
The only way I've been able to sync flv's is using
progressive download. With progressive, you can sync streams, but
the accuracy is limited to the keyframe interval of the flv files.
For example, if you have 2 keyframes per second, you can achieve
sync with 1 second accuracy. with 4 keyframes per second, you can
get the offset down to 500ms. If you make every frame a keyframe
(makes for a huge file), you can get frame accurate sync.
The theory is to build a class that monitors the time and
buffer length properties of your two streams, pausing and/or
seeking when needed to maintain sync.

Recording 2 audio streams separately with iChat?

Is there a possibilty to record the iChat video chat with the 2 audio streams in separate files? (so one for the video, one for the microphone and one for the speaker)

Hi,
No, the Audio is Full Duplex meaning that both ends can speak at once and be heard by the other.
The iChat Recording option records the Audio as Mono and combined from both ends. (At least in versions prior to Lion - I have one Lion/iChat recording and it is listed as being in Stereo but again the Audio is from both ends).
SoundFlower may possibly be able to grab either the Local Audio (mic Input) or the Output (which is Buddy).
I have never used it and don't know if it can record two things at once. (It seems to stop at the Leopard version)
Audio Highjack Pro (there is no NON Pro version any more) might provide another answer (but it will cost)

Recording multiple audio files

Hi,
Is it possible to have a program that will record separate audio files every time the user presses stop and save? Would the solution for this be a state machine...? How could I update the Sound File Open and Output Configure VI's if they are outside the while loop? I am guessing that I could implement this by putting the state machine within another while loop?
Anton

Assuming that you only want to record a single file at a time...
State machine with 4 states - idle, start, read and stop. When you press the start button you go from idle to start and start the sound acquisition. Then you stay in the read case - reading the samples and writing to the file (possibly using producer/consumer architecture with a queue) until the user presses the stop button where you go into the stop case to stop acquiring the sound data and go back to the idle case.
You could use an event structure to process the button presses.

Multiple audio streams for 1 video track

Hi I have a few different sountracks I want to use with one video asset.
I want to avoid duplicating the video track and putting a version of the audio in it.
If I have an Audio tab in my menus with music and lyrics, one with instrumental only and a dolby 5.1 surrond
how do i target the buttons to choose different audio as i click on the 5.1 let's say, it will choose to play stream #3 5.1 surrond.
Been looking in the manual but could't find anything.
Any help is appreciated
thanx
jm

Sorry about the links -:(
Anyway follow these steps and it should work (one approach, not difficult to do, I just wrote the steps in small bites )
Press F3 Key so we are looking at the same layout in DVD SP
1.) Make a menu with two buttons, label them Audio A and Audio B
2.) Make a Track (the "TRACK")
3.) Place your video on the video portion of the TRACK
4.) Place your Audio A on A1 track and Audio B on the A2 track
5.) Drop a chapter marker at the end of the TRACK (one should be at the begininng of the track by default)
6.) Click Add Story from the top Bar for the TRACK
7.) Name that story Story A, add the first Chapter Marker to the Story
8.) In inspector for Story A deselect/remove check marks for all audio except for 1 (uncheck 2-7)
9.) Duplicate Story A as Story B
10.) In inspector for Story B deselect/remove check marks for all audio except for 2 (uncheck 1, 3-7)
11.) Set Button 1 from menu to Story A, Button 2 story B
Note that this method will not allow toggling between the audio. A quick way to permit toggling is to do as above, but have both Audios (1 & 2) checked in steps 8 & 10
Create a script called PRESTORYA and set it as a prescript for Story B, with the following:
Set System Stream AU(Audio Stream 1)
Create a script called PRESTORYB and set it as a prescript for Story B, with the following:
Set System Stream AU(Audio Stream 2)
FWIW the links worked just now (downloads a zip file directly to HD, take a look in activity window in Safari, maybe there for you?)

MPEG with multiple audio streams

I have a dvd that has one video on it with 4 different audio options. The goal is to recreate the dvd with different menu's etc. I ripped the dvd with MPEG Streamclip. I played the ripped mpeg and it definitely contains all four audio streams. I then imported the mpeg into encore cs4 and it only shows the default audio selection, the other three are gone. I tried importing it into premier and the same thing happened. This seems like it should be pretty easy but maybe not.
Thanks for the help,
Kevin

Kevin,
First, welcome to the forum.
Next, I am shooting blind here, as I have never gone this direction. If none of this works, sorry. I only go the other way, creating what you hope to recreate.
Now, what happens if you rip the Audio in a Multi-track Audio editing program, like Adobe Audition? I would hope that it will rip each Audio stream as a stereo WAV (or as discrete WAV's if you have AC3 DD 5.1 SS). If this does work (remember, no guarantees), you should be able to separate these out, and then Import them into Encore.
I am sure that many other programs can do what Audition does, but that is my go-to Audio editor and know that it works well with both ripping from all sorts of muxed AV files, and will also handle Multi-track material.
Good luck, and please let us know if this works. Also, Neil Wilkes, a valued contributor to this forum, is the "Audio guru," and might well have better suggestions.

Can Premiere Pro CC handle AVI files with multiple audio streams?

I have an AVI file with two audio streams and I am wondering if there's any way to access the second stream in PP? So far I can only get the first stream to play. I know I can extract the second stream in for instance VirtualDub, but it would be nice to not have to do that in the interest of an effective workflow.

Hello again Jim! Thank you for your reply, you seem to be working hard here on the forums! The info I have found from 2011 suggested that it wasn't possible then, but I was hoping maybe they added this feature.

Recording Multiple Audio Tracks - delay problems in 7.2 Pls HELP

Hi, I'm finding very buggy behavior - if I record across several audio tracks (say 5 mono channels) for longer then 10-15 sec. Logic HANGS for a long time when I'm done with a take - 15-25 secs of the spinning ball icon, and then will redraw and start the dialog box that says it's computing the overview. I'm currently on 7.2.2 but I also tried going back to 7.2.1 and it's still doing this. I have the "faster overview calculation" box un-checked, but it didn't seem to make any difference either way. I also tried this on a new file, same problem -
I also already tried recording to different drives, and selecting and unselecting the 'record limit' dialog in the record destination dialog - I usually have this set to a max recording time of about 7 minutes. None of these changes affected the sluggish behavior.
Anybody else know of this and know of a fix/workaround? I have a session to record tonight with multiple players and this session is going to go like molasses unless I figure this out!
thanx

Hmm, I've never had anything like this. I'm wondering whether it indicates an underlying disk problem?
Try running repair permissions and a disk diagnostic tool if you have it. Are you using an internal or external drive? Try recording to a different drive if you can and see whether the problem persists.
You could also try creating a different user and running Logic under that account, to see if it still shows the same behaviour (if not, then it could be a user permissions issue or something funky with your user account).

RECORDING MULTIPLE AUDIO TRACKS AT ONCE

Hello. Looking for some help. I am using LOGIC PRO and a Presonus Project Studio 8 input AD converter. I have 6 drum mics up and Presonus is recognizing them. I have created 6 audio tracks in Logic and named them appropriately. I go to record them and all I get is the kick drum...no other mics are recording on their own tracks....
Can someone help guide me?

Three ways of doing this:
In your mixer slide over the tracks with your mouse - they all turn white/grey - hit record on one of the tracks - all tracks will get armed with the red flashing R button.
or
Hold the shift key and select the tracks in your Arrange - arm one of them - all tracks go into record mode.
or
group the tracks together in a group via the grouping slot above the channel fader, in the group options menue select record enable - arm one of the tracks - all tracks go into record mode.
