Audio file requirements

2 min readUpdated 14 July 2026

Saga20 accepts one MP3 or M4A file for each audio session.

Requirement Current limit
File type MP3 or M4A
Maximum file size 400 MB
Maximum recording length 7 hours
Files per session 1

FLAC, WAV, MP4, and separate speaker tracks cannot be uploaded directly. Convert or mix them into one MP3 or M4A file first.

  • Use compressed audio rather than an uncompressed format.
  • Mono is usually enough for spoken tabletop sessions.
  • Keep every speaker in the final file.
  • Play the beginning, middle, and end before uploading to check for silence or missing audio.

The file must contain spoken audio. A silent or nearly empty recording cannot produce a useful session.

If your file is rejected, see Fix an audio upload problem.
