Hi,

I am developing a sound recorder that can rcord sound in PCM format with 8000 Mhz and 8 kb/s sampling rate.

I am able to record the sound from Microphone but not able to save in this particular format. So how do I save the particular format from VB.

So please help me in this particular matter.


Regards
Shaival

First record an "empty" sound file (.wav) setting the parameters you need : you can use the standard MSSoundRecorder. Click on file>properties click convert button and choose PCM 8000 Hz, 8 bit 7/kbits second.Start recording from microphone : record some seconds (you can record no sound). Save your file as empty.wav.
I suppose that in your VB application you are using  the MCI Control. If so,  initialize your MCI Control loading the empty.wav file :

MMControl1.filename = "C:\Myfolder\empty.wav"

After recording a new file, use the command property :

MMControl1.filename = "C:\Myfolder\Mysound.wav"
MMControl1.Command = "Save"

You will find a file "Mysound.wav" that has the same properties of "empty.wav" (PCM 8000 Hz, 8kbits second...).

If you need a sample code using MCI Control let me know. I'll post it.
Hope this helps..
