Audio Tools

Trim, edit and convert audio files locally.

Audio Studio handles quick audio edits locally: trim a clip to length, adjust volume, convert between MP3/WAV/M4A/OGG, and change playback speed.

Like Video Studio, it runs FFmpeg in WebAssembly inside your browser — your audio file is never uploaded.

Useful for voice notes, podcast intros and simple format swaps. Preview after volume or speed changes; extreme boosts can clip and distort the waveform.

Common tasks

  • Trim a podcast intro or voice note
  • Boost or reduce volume before publishing
  • Convert WAV to MP3 for smaller file size
  • Slow down or speed up a recording
