About SDS Files

.sds Icon

An .sds file is an audio file saved in the MIDI Sample Dump Standard (SDS) format, a specification for transferring raw digital audio samples over MIDI. SDS files store uncompressed sample data along with basic information such as sample length, bit depth, and loop points, allowing compatible hardware and software to reconstruct the audio accurately. Unlike typical audio formats meant for playback, SDS files focus on precise sample exchange rather than compression or streaming efficiency.

The SDS format was introduced in the late 1980s and early 1990s and was commonly used with hardware samplers, synthesizers, and early digital music workstations. Musicians, sound designers, and producers used SDS files to move samples between devices from different manufacturers when proprietary formats were incompatible. While the format is less standard today, it is still relevant for archivists and musicians working with classic samplers or restoring older projects. Users can open and play .sds files on FileHelper.com by dragging them to this page.

Converting SDS Files

You can convert .sds files to other formats to improve compatibility:

  • Converting to MP3: Makes SDS audio playable on nearly all devices and media players, though it applies additional lossy compression that slightly reduces audio quality compared to the original file.
  • Converting to AAC: Provides efficient compression and good sound quality, producing smaller files than MP3 while maintaining compatibility with most modern devices and streaming platforms.
