Supported file types

Medallia Speech supports the following file types for transcription:

  • FLAC
  • AAC
  • Opus
  • MP3
  • WAV
  • AVI
  • OGG_OPUS
  • M4A
  • MP4
  • PGP/PGP

Lossless compression formats (such as FLAC) are best, because they optimize for network bandwidth when transferring files to Medallia Experience Cloud. If you use lossy compression formats (such as AAC and MP3), ensure the compression is tuned to not disrupt audio recordings more than 2%. Lossless formats are preferred.

Tip:

While Experience Cloud supports all formats listed above, we recommend using the following formats (in order of preference):

  • FLAC
  • AAC
  • Opus
  • MP3
  • WAV

Files cannot be zipped. Files can be encrypted with a dedicated Medallia Speech PGP key. For more information, see the following guides:

Note: If you do not see your preferred file type listed in this guide, contact a Medallia expert to discuss alternatives or the possibility of supporting a new file type.
