Hello,

We have a DSP based hardware mixer in our audio device which can mix multiple audio streams. It can also add effects to the individual streams. Currently, we plan to provide the support for this 'stream' mixer through the wave API.

We will initialize the mixer at system startup and all the remaining waveOpen() would just plug their output into this line. We propose to expose this functionality thorugh the WaveDriver's IOCTL_WAV_MESSAGE.

My question is how is this related to the HW audio mixer API. How would my application which would be using handles from Wave API can use this Mixer API for effects etc.

Best Regards,
Ankur Pruthi
