Projects / listener


listener is a typical security-related program like the motion package (which detects motion on a Webcam): it listens for sound. If it detects any, it starts recording until the sound stops (or a bit later, which is configurable). It stores the audio in .WAV files.

          Release Notes: 'on_event_start' can now specify what script to start as soon as the recording starts. One can now use a fixed amplification factor. One can now let the listener store the audio recorded before the sound started. 'setlistener' stopped working, and has been fixed.

            Yes, nice program, worked fine for me too. I like the background mode, it is really like a spy, so, be careful about what you will do with it!

            The program have worked great for me but the filters packaged with it makes the program to seg fault. If anyone have build any good filter please let me know.
