Which audio files can S9 Sampler import on Linux?

On Linux, S9 Sampler imports WAV, AIFF, FLAC, OGG and MP3. CAF is an Apple format and isn’t supported there. If a file won’t load, check its real format before you change any MIDI or audio settings.

Renaming a file doesn’t change its format. A .wav name on an MP3 file is still an MP3 inside.

For S9 Sampler 0.1.6 (paid beta).

Step by step

  1. Check the file

    Start with a WAV, AIFF, FLAC, OGG or MP3 you know plays. Make sure it is an audio file, not an archive or project.

  2. Use the Linux build

    Use the Ubuntu 24.04 x86_64 VST3 from the S9 Sampler page, with libgomp.so.1 installed.

  3. Load it

    Load the file with Load Sample. If the waveform appears but you hear nothing, check the track, mode and output instead.

  4. Convert if needed

    For CAF or another format, export a WAV from software that can open it. Keep the original.

Good to know

Try a second file

A second known-good file tells you whether one file is the problem. Mention the format if you report it.

Importing isn’t recording

Your DAW handles playback and MIDI. Recording uses PulseAudio or PipeWire-Pulse. Neither changes which files you can import.
