Audio Compressor

Turn bulky WAV recordings and large audio files into compact MP3s for sharing, podcasts and voice notes.

How to use it

1. Use 64 kbps for speech-only recordings — intelligibility stays high at a fraction of the size.
2. Use 128 kbps as the all-round music setting and 192 kbps when you can hear artefacts on headphones.
3. Stereo is preserved for stereo sources; mono sources stay mono.
