A Guide to Saturn Music Formats: SCSP, Redbook, and More

The Sega Saturn has a rich history of innovative audio capabilities, with various music formats used throughout its library. In this article, we'll delve into the different types of audio formats found on the Saturn, including SCSP, redbook, and streaming audio.

SCSP (Saturn Chip Music)

SCSP is a proprietary audio format developed by Sega for the Saturn console. It uses the Saturn's onboard audio chip to play back music files in .ssf format when ripped from the game. Many games used this format, including some FM synth-based titles like 'Lockwork Knight'. The SCSP chip can produce high-quality sound effects and music, but it has its limitations.

Redbook (CDDA)

Redbook audio is a standard CD audio format that uses the Saturn's built-in CD-ROM drive to play back music. This format was used in some games, such as 'Myst', which features 39 tracks of redbook audio. Redbook audio offers higher sound quality compared to SCSP, but it's limited by the CD-ROM format.

Streaming Audio or Yellowbook

This format uses 1-2 channels of the SCSP chip to play back longer music files. It's also known as 'yellowbook' due to its yellow-colored audio waveforms. Some games, like 'Double Trouble', use this format for their soundtrack.

Other Formats

Some games used samples and FM synth for their soundtracks, while others employed a combination of both. For example, 'Mahjong Gokuu Tenjiku' features redbook-only audio, but the downloaded OST includes additional tracks in SCSP format. Similarly, 'The Mansion of Hidden Souls' is 1ch streaming only, with one track at 22khz.

The Saturn's music formats are complex and varied, with each game using a unique combination of audio technologies. By understanding these formats, you can better appreciate the soundtracks of your favorite Saturn games. Double-checking your downloaded OSTs for missed uploads and verifying the formats used in Yabause will ensure that you're getting the best possible listening experience.
