Which audio formats are supported?

Joplin version: 2.4.9, Linux, AppImage

I added a FLAC file to a Joplin note. It seems to be recognized as an audio format, because the playback controls appear, but the controls stay greyed out. Other formats like WAV play fine.

Is FLAC a supported format? Is there a list of supported formats somewhere?

Edit: issue raised on Github: FLAC audio files show greyed-out audio player · Issue #6434 · laurent22/joplin · GitHub

So if do a bunch of assumptions, then Joplin is based on Electron which is based on Chromium. Chromium supports the following codecs and thus Joplin should be able to play FLAC...

  • FLAC
  • MP3
  • Opus
  • PCM 8-bit unsigned integer
  • PCM 16-bit signed integer little endian
  • PCM 32-bit float little endian
  • PCM μ-law
  • Vorbis
