Hi

@Boris S: Thank you a lot for the presentation.

@Lars V: Yes I totally agree with you, I remember that when I
discovered Bosst some years ago I event thought it was for Steinberg
ASIO, I think I will try to specify Steinberg or Boost.ASIO all the
time to be clear.

@Brendon C: Yes this is my first concern. In fact I have more
experience in audio threads, than in Boost.ASIO.
I suppose it should be possible, basically I think this is a compmlete
kind of new Boost.ASIO service (not networking, neither, serial or
anything else).
Also the purpose of the lib would be to provide a socket equivalent
that can request the audio service to open an audio device, and then
connect on it an audio callback which will be called in the audio
thread.
I don't expect any of the service, or socket to be called in the audio
thread. i suppose that the user will open the device from a user
thread. and connect his audio callback.
The only thig that I may implement in the audio thread is the buffer
desinterleaving, or the format conversion, but this will be specific
function not related to the rest of Boost.ASIO and should not be a
problem

I'm also wondering how to selec the driver family.

On MAC there is Coreaudio, which handles all the devices
On Win, there is wasapi, directx, Steinberg ASIO familys of driver
which can all map any device (as long as the manufacturer provided a
compatible driver).
On Linux, there is Alsa and PulseAudio I think.

I guess this should be choosen when creating the socket.

Thank you for your feedbacks

Hi Adrien,

I just wanted to chime in and say that I think this is a fabulous idea. I 
have wanted something like this to be available in Boost for a long time. I 
would be more than willing to help contribute code if I can, as I have done 
some work with audio I/O under Windows. I can also do testing, should you 
find it useful.

Kind regards,

Philip Bennefall
