The FreeDSP app

Get the native app

The browser version is free, with every effect, and stays that way. The app is made for continuous use and uninterrupted sound, when every millisecond counts: the same effects and the same screen, talking straight to your audio hardware.

Ultra low latency

About 12 ms from input to output, not 40. It feels as immediate as a pedal.

ASIO support

Works directly with pro audio interfaces through their ASIO driver, for the lowest latency your hardware can reach.

Uninterrupted sound

Lock your screen, close the window or switch to your backing tracks, lyrics or setlist. Your sound keeps going.

Higher sampling rates

Run at up to 96 kHz, for even lower latency and cleaner high-gain distortion.
