Integrated System for Holistic Multi-channel Acoustic Exploration and Localization

Features:

Ishmael is a freeware, multi-purpose acoustic analysis tool. It is primarily for at processing real-time sound, but it can also read sounds from a file, or a sequence of files.

Ishmael includes:

spectrogram viewer
real-time sound recording
acoustic localization methods
automatic call detection
beamformer
log file annotation feature

Ishmael is capable of processing large amounts of sound data quickly and relatively easily. The sound can be a collection of sound files, or a signal arriving in real time from one or more microphone(s) or hydrophone(s).

Ishmael is not particularly well-suited to sound exploration-taking an unknown sound and examining it in detail to find out and measure its characteristics. See the links page for software that may fit these needs.
