|Hannes Seifert Composition|
Hannes Seifert Composition (HSC), the full name is a guess, is an audio format that stores instructions for a sound card equipped with an OPL2 (AdLib, Sound Blaster, etc.). The format was designed, programmed, and implemented by Hannes Seifert. Seifert used this format in several of the games he helped develop in the mid-1990s.
The format and player was reversed engineered by demo scene and a group called the Electronic Rats built a tracker around it called the HSC-Tracker. This caused the format to become especially popular. Eventually, someone called Number Six created a compressed version of the format called "HSC Packed" which uses the extension *.hsp.
