Real time management of audio inputs/outputs?
 
Howdy There,

I was wondering if there is an application for Ubuntu (FOSS or otherwise) that would allow me real time management of all of my audio inputs and outputs.

Essentially I have multiple microphones attached to my computer and multiple audio outputs. What I am looking to do is to be able to assign each different input to it's own audio output. A touch screen interface is a plus for the program but not necessary.

Anyone know of software that does what I am describing?

Regards,
~Jeff

Jack ?

Maybe I am just not understanding the GUI/documentation (only glazed over it, going to read more of it later). But is Jackd for managing application's sound output only or is there a way I can capture audio input and control where/how it pipes back out of my system?

If you scroll down to the jack entry:

Is that what you mean?

You'd also need a real time OS.

Yes, you need both jack and real-time kernel (which you will probably have to compile).

what part has to be real-time
 
Hello, perhaps it may sound pedantic, but what aspect in your application has to be real-time?

Is it that you want to define the routes of audio inputs to outputs using some form of GUI, and then the actual audio signals have to be routed or mixed and filtered by some audio processing software in real-time, i.e. in a deterministic fashion and within a given time delay? In this case there was several years ago a project call RAT - http://www.linuxfordevices.com/c/a/L...e-Audio-Tools/

Or is the emphasis on "real time management", i.e. you want to manage the input/output routing in "real-time", meaning whenever you change something like the routing in a GUI, you want it to take effect in "real-time", possibly meaning within a humanly not perceptible time delay, but the signals are actually routed in hardware. In this case you do not require any real-time kernel.

Cheers,
peter

Real time audio has great advantages to users that require music to be presented while at the same time being recorded. Many people can hear that the recordings are off and it is difficult to correct in post processing.

Perhaps you can start with building (configure and recompile) a less preemptive kernel?

I think ubuntu studio will install the RTOS kernel if you select the audio packages. It really may be the best starting point unless you really know a lot about QNX.
