    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.
