JSoundspy records sounds from the main input line (usually, mic), and create some 15s OGG files when the sound reach a threshold (in dB). It can run during days.

JSoundspy needs Java 1.6 or more (and, fyi, use libvorbis/libogg from the Xiph.org Foundation).

JSoundspy is freeware.

Download JSoundspy.
