[vbox-dev] VRDEAudtioSamples

[Sriram Murthy]

Hi,
     I am trying to write a simple extension pack for a college project, that reads the AudioSamples being provided by VRDEAudioSamples to be played back by an ALSA player.
     As a first step, I want to save the samples to a .wav file, so that aplay can read it and play it. Towards this, I have the following questions, and will be glad if someone could 

     please answer these questions -
     1) How to convert the various values encoded in VRDEAUDIOFORMAT to nSamplesPerSec, nAvgBytesPerSec, nBlockAlign and other information required for a wav header?
     2) How do I interpret the data in the buffer that is being provided as part of VRDEAudioSamples?
     3) Also, how do I calculate the total number of bytes that are being passed as part of VRDEAudioSamples?

Regards,
Sriram
