RecAll AudioCapture - Version 2.3 Works like a voice-activated recorder for your computer. The program runs in the background, monitoring the microphone input of your sound card. Sound above a settable threshold triggers recording of .WAV data to disk. Recordings may be time-stamped. Suggested uses include a handy note-taker for ideas and dictation, unattended monitoring of radio scanners, and security monitoring of your work environment. Sound card with Automatic Gain Control (AGC) microphone input recommended.
