Frequently asked questions
Does speed change pitch?
The tool uses an atempo chain so playback speed changes while pitch stays closer to the original than a simple sample-rate stretch.
What range is supported?
From 0.25x to 4x. Extreme values may sound less natural on complex music.
Are my files uploaded?
No. Speed change runs entirely in your browser.
