Dynamic Studio Professional allowed musicians to compose songs by arranging audio samples in a grid-like interface, defining each sound's pitch, effects, and timing. The software was prevalent in the demoscene and video game development communities for its capabilities in creating multi-channel, sample-based music that worked efficiently on their limited hardware (mainly DOS-based PCs). While Dynamic Studio Professional is no longer actively developed and the DSP format has become obscure, retro audio enthusiasts may still use DSP files.

You can open DSP files with MODPlug Player in Windows and CocoModX in macOS. However, both programs are discontinued.
