Apple

there are open source projects such as JACK that do what you are interested in, at least in part but please plan to respect the licensing used. also, be aware that any particular app that does this typically represents only 1 of several different approaches to the problem.

Hi there,

I 'm building a solution which purpose it's to create a input device for applications to use however, the sound input doesn't come from an hardware device. The idea is to make it come from an user space audio source.

My first approach was to create a kernel driver based on the SimpleAudioDriver with one stereo input source only.

I have already a kernel extension creating the device driver and the applications can actually see it.

My question now is, how is the proper way of injecting audio onto this device driver from user space, in order to keep latency as low as possible?

I thought that it might be possible to create a user space device driver but i'm not sure of it since its my first step into CoreAudio API's. Is it possible? Or am I making the right choices so far?

Is there any example in particular that I should focus my attention on?

I would definitely love to hear the opinion of experienced users.

Thanks in advance,

With my best regards,

Nuno Santos
