A question of sound

is there anyone who know how's to get a hold of the master sound mixer under windows? i need to be able to read sound that is coming in such as from a microphone. i don't need to save it in a file, i need to stream it and analyze it on the fly. any ideas?

    Use DirectSoundCapture.

  • i know how to do it under directX but i am trying to do it using only the win32 services. i want this thing to run on NT and 9x.

    Why NT 4? It's not as if we haven't had Win2k for a year now. DirectSoundCapture is available on all versions of 9x and on 2000, and is available as an unsupported add-on for NT4, too.

    Anyway, the other way is to use the low-level multimedia I/O services. Look up waveInOpen and go from there.

    They are for the mixer devices, used for selecting record inputs, record levels, playback levels, pan, et cetera. The Volume Control applet basically exposes all the mixer functionality.
