A program for analyzing temporal pattern intervals in repetitive, animal sounds

Software for measuring temporal pattern intervals of repetitive animal sounds is described. The program measures time intervals of digitized sounds, plots frequency distributions of these intervals, and calculates descriptive statistics. The program is written in THINK Pascal and is currently interfaced with a sound digitization and analysis software package for the Macintosh computer (SoundWave, Impulse, Inc.). However, the algorithms can be incorporated in any hardware/software environment for the digitization and analysis of a variety of repetitive, pulsatile animal sounds.
