Spectromatic - an audio spectrogram program
News
31st March 2002 1.0 released!
Introduction
Spectromatic is a program for generating spectrograms from audio files.
Spectrograms are a form of simple time-frequency analysis which lets you see
how the distribution of energy at different frequencies in an audio stream
change over time. For example, if you play a scale on a musical instrument,
you will see a climbing and/or descending pattern of blobs as you move from
left to right.
Spectromatic reads its input as mono or stereo 16-bit wave files, and
writes the output image to an elongated PNG image (colour for stereo,
grayscale for mono audio).
