Abstract
A hardware and software system and method for a personal computer such as the Macintosh allows recording, editing, and playback of sound. The system includes a sound editor which displays sound waveforms, and permits the user to mix together several simultaneously displayed waveforms, and to change the pitch and amplitude of one part of each waveform by means of a novel screen display.
