ToneCalculator helps you bring your songs in tune. Finding the right tempo that fits best to your song.

When something swings below 20 Hertz we can’t hear the frequency but perceive it as rhythm. So the tempo is a frequency below our hearing range, but still a frequency that is either in tune or not.

A big part of music feeling natural is having every part of the arrangement and environment being in sync with the other elements surrounding it. So ToneCalculator also provides you with the correct (in sync) data for your Delays, LFOs, pre delay times of your reverb, attack and release times of compressors and other envelops.
