Slow Down Audio

Make your audio slower – speed factor from 0.25x to 1x (MP3, WAV, OGG, M4A, FLAC)

Drag & drop an audio file or click to browse

How to slow down audio:

  1. Select an audio file (MP3, WAV, OGG, M4A, FLAC, etc.)
  2. Adjust the "Speed multiplier" slider in the settings panel (right) – values below 1.0 make it slower
  3. Click "Preview Speed" to hear the effect (no file saved)
  4. Choose output format (MP3 recommended) and bitrate
  5. Click "Slow Down & Export" – the slower audio will be created locally
  6. Download the result and enjoy relaxed playback (pitch decreases naturally)

All processing happens in your browser – files never leave your device. 0.5x speed = double duration, lower pitch.
