The IS file extension is associated with Sound Invasion Music System v1.2, whose editor is called InStereo!. The format is intended for music rather than ordinary recorded audio.
An InStereo file can contain four voices, synthesised sounds and samples. It also stores sound and playback data such as an ADSR table, vibrato, an envelope-generator table and portamento.
InStereo is legacy Amiga software. On current Windows systems, Amiga Forever can provide an Amiga environment in which the original software and its files can be used.
Open the file in the InStereo! editor within an Amiga environment. On Windows, Amiga Forever can be used to run compatible Amiga software; the file may not open directly in a modern Windows audio player.
To obtain standard audio from an InStereo file, play it in InStereo and record or render the playback to a format such as WAV using suitable Amiga or host-system audio software.
