Questions
Does reversing affect every channel?
Yes. Every channel (left, right, and any others) is reversed so the file plays correctly in mono and stereo.
Does my audio file get uploaded?
No. The reversal runs entirely in your browser. Your file never leaves your device.
Why is the output a WAV file?
WAV is a lossless format the browser can write without a separate encoder. You can convert it to another format after downloading.
Which audio formats can I use as input?
Any format your browser can decode — MP3, WAV, AAC, OGG, FLAC, and M4A work in most browsers. The tool will report an error if a format is not supported.
