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: This is a maintenance release, fixing all kinds of small bugs.
Release Notes: This version now uses portaudio. This means it is more stable and should run on other platforms (such as Mac OS X). This version also has a new, more flexible commandline format for selecting sample rate and such.
Release Notes: This version supports ALSA for sound I/O. The "on_event_start" handling was fixed. Listener can now write its PID to a file when running in daemon-mode. One-shot recording was also added.
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.
Release Notes: The output filename can be defined with a template, audio can be automatically amplified, audio recorded before the sound starts can be stored to disk, recording from stereo sources now works, and a Makefile has been added for FreeBSD.
