I have code which records from soundcard. I saves values in RAW format.

What should I do that it shows some numbers instead of RAW strange alphabets.

Each sample should include amplitude of sample, I would like to see what amplitude was.

The program does not choose the input. You have to do it, instead. The easiest way is via Volume Control - double click at the speaker in the system tray, choose Options/Properties/REcording and click on OK. Then you will receive volume controls for recording, where you can enavle/disable inputs.

Best regards,
