Audio
On Lyda, we serve all audio files in mp3 format. The available bitrates are: 92kbps, 128kbps and 320kbps.
We use ffmpeg for converting uploaded files to the target format. If you encounter any issues uploading files, we recommend trying to run a local conversion of the file (replace "%file%" with the actual path to the file on your system):
ffmpeg -probesize 50M -analyzeduration 100M -i %file% -ab 320k
If that works, the issue might be with analyzing the loudness data of the file:
ffmpeg -i %file% -af ebur128
