Frequently Asked Questions
Are my files uploaded online?
No. All processing happens in your browser: no file ever leaves your device.
Why won't the volume go past a certain point?
With anti-distortion on, gain is capped so peaks don't exceed 0 dBFS and distort. Turn it off to push further, at the risk of clipping.
