Frequently asked questions
Does reversing change pitch?
No. The waveform is played backwards without pitch shifting.
What formats are supported?
Common audio inputs work, and output supports MP3/WAV/AAC.
Will this reduce quality?
Reversing requires decoding and re-encoding. Use WAV output for maximum fidelity.
Which browsers are supported?
For best results, use the latest Chrome / Edge with WebCodecs support.
Is there a file size limit?
Processing runs locally, so very large files may take longer depending on your device.
