Hello
Does anyone know how to catch the data from a soundcard, loaded into the card via a microphone. It shall be the raw PCM data.
Best Regards
Kresten

Check out AudioLab from http://www.mitov.com, it does exactly what you want,
and a lot more.

Hi, thanks for your help.

I have now installed AudioLab3.0.
I think that the component TALAudioIn takes the microphone input as default, is that right? (Right now my microphone input does not work).
But I have some raw PCM data that is sent over an UDP connection, so I need to be able to put the raw PCM data into the a AudioLab component, and to get out raw PCM data, is that possible?
If it is, how do I then setup the device property in the TALAudioIn component.

Best Regards
Kresten

Yes, TALAudioIn is for capturing audio from the soundcard.

If you're receiving the raw PCM data, then can't you just use it? I'm afraid
that I don't quite understand where the soundcard comes in.

Hi,

The data from the Microphone shall be send to a radio via UDP/IP, and the data received by the radio shall be sent to the soundcard in the PC. The data in and out the radio is raw PCM data, so the data from the microphone should also be in raw PCM when it is send to the radio.

Best Regards
Kresten

What jack on the PC is used to send the data to the soundcard? TALAudioIn
should work for this, you'll have to configure the sound card on the PC to
record from the correct jack though.
