The Magic Behind the tonestro App

February 27, 2019

What’s tonestro?

tonestro, as you probably know, is the world’s first playful practicing app for wind musicians which gives you live feedback while playing and connects musicians worldwide. Simply put, it efficiently improves your skills without costing a thing.


How is this achieved?

This is done through the instant feedback feature. This is the process in which the user (you) downloads the app, plays the desired instrument (the recorder, to say), and gets immediate feedback on how they can improve.

In this blog post, we’ll unveil the secret behind our signal processing and algorithm work while one is practicing. Let’s take the recorder, for example.

Imagine you’re rocking it. Each tone you are playing is inherently just a sound wave. We are able to extract information from the waves by using different methods, i.e. Fourier. Each information is prepared differently depending on the instrument. Thanks to our signal processing and algorithm, the app will analyze your performance, derive insights from it, and present them to you in a timely manner.


And how does this work?” I presume you’re asking yourselves right now.

Through intelligence algorithm, of course. The intelligent analysis algorithm is capable of digesting large chunks of data and breaking them down into insights.

The algorithm is comparing your pitch, rhythm, articulation and dynamic to what the system knows is correct for the given instrument and song.

The given feedback is:

  • Accurate
  • Effective
  • Impactful
  • Delivered in a timely manner

It has the ability to turn underground wind instrument enthusiasts into perpetuated worldwide-renowned musicians.

This is our superpower! What’s yours? If it is rocking your audience with wind instruments, you’ve come to the right place.
