SoundDesigner II

Developed by Digidesign in the late 1980's, Sound Designer and Sound Designer II are audio recording and editing software used on the Macintosh platform. Sound Designer II v2.8.3 was the last version released and was never tested in OS 9.

File Format
Sound Designer II files store all sound samples in the Data Fork and all sound parameters in the Resource Fork.

An SDII file can be monophonic or stereophonic. When stereo is used, the tracks are interleaved (sample-001-left, sample-001-right, sample-002-left, sample-002-right, etc.)
