audio recording

[kadkir]

I am trying to record a wave file using "winmm.dll" from a web application. I am able to record that .WAV file in 11025 samplespersec, 16 bit, mono format. But my requirement is to record that in 8000 samplespersec, 16 bit, mono format (wave format). How do I meet my requirement ? Is there any other DLLs or ActiveX control to meet my specifications ? thank u all.... with regards, kiran

Have you got a copy of Goldwave? I'm not sure if it's open source these days but it is the business when it comes to audio formats.

Nothing is exactly what it seems but everything with seems can be unpicked.

You can simply change these things in the header that is prepared for recording as well as file writing. Have you look at the code in deep?

So you're using the waveIn___() APIs? If so, you can specify the format you want to record in your call to waveInOpen() (see the WAVEFORMATEX struct parameter). Mark

I did the same using set command string (passed as param to mcisendstring function). But I am getting "value out of range exception..", what to do with this ? thank u, kiran.
