A multi-purpose tool for spectrograms, localization, recording, call recognition, etc.
By Dave Mellinger
Ishmael is a multi-purpose sound analysis tool. It is primarily aimed at processing real-time sound, but it can also read sounds from a file, or a sequence of files.
Ishmael makes a running spectrogram as it receives a sound. Using the mouse, a user can choose parts of the spectrogram to perform various types of acoustic localization. The user can also make a sequence of annotations to describe features of the sound.
Another part of Ishmael is for automatic call recognition (ACR). Ishmael currently has three algorithms for ACR: measuring energy in a band, matched filtering, and synthetic spectrogram correlation. When it detects a sound, it can note that fact in a log file and/or grab the detected sound and save it out in a soundfile.
Ishmael also has the capability to continuously record sound from the input source to a sequence of soundfiles. Using this feature, it's possible to convert sound files from one format to another.
