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.


Version 2.1

* Preferences window to configurate ToneCalculator to your likings:
- TapTempo with or without sound
- ToneCalculator always on top or normal window
- Volumes for the accent and offbeat of the metronome

All I wanted was a flexible metronome and a way to generate a pitch to play along with for intonation purposes. This app does both and more! Perfect!

Thanks, for your comment!

stays in focus even when you move to other apps : (

Good: Tap tempo, start/stop via hitting “m”; fairly easy interface, albeit cluttered; other nice-to-have features for a metronome.
Bad: App’s main window emains “in front” even when you select other apps. It should “go back.” Essentially, you have to quit it to make its window go away so you can see any other app. This is a dealbreaker for me, if developer could fix this I’d happily pay for the app.
Also would prefer if it didn’t make a sound when you hit tap tempo. As a piano teacher I use metronome apps to tap a student’s tempo without them getting distracted by hearing a click. I don’t want to have to turn the volume down to tap tempo, only to turn it back up when I want the Metronome. AFAIK, there’s really no need for Tap Tempo to ever make a sound for anyone.

Thanks for your comment. You can choose now in the latest version, if you want Tap Tempo without sound and if you want ToneCalulator to behave like a normal window.
