Use this tool to convert music from a source frequency (such as standard A 440 Hertz) to a target frequency (such as 432 Hertz, 444 Hertz, and other frequencies). If you are logged in you can opt-in to get notified by email once the conversion is finished.

Source file

Local file:

Remote URL:
You can either enter a remote URL (e.g. a location where the source file is located) or a local file from your device. If both, an URL and a local file are selected then one of them is ignored.

Source frequency (Hertz):

Target frequency (Hertz):

The source and target frequency are both with respect to the standard A (usually 440 Hertz). Please use the 440 Hertz Music app for non-standard frequencies.

Audio format:

Algorithm:

Two different algorithms are provided - a time-based and a frequency-based (FFT). Generally Algorithm 1 yields better results, but depending on the input music also Algorithm 2 can sound better.
