Music Tools for Desmos is a Chrome extension that enhances the audio trace functionality in Desmos. With this extension, users can enable a wider frequency and duration range for the audio trace function, allowing for more comprehensive music exploration and analysis.

The extension expands the frequency range from ~E4-E5 to A0-C8, providing users with a broader spectrum of musical notes to work with. Additionally, the maximum trace time is extended from 20 seconds to 320 seconds, giving users more flexibility when creating and analyzing musical compositions.

To ensure optimal playback, users need to set up their viewport correctly, with x values ranging from 0 to the desired audio speed in seconds, and y values ranging from 0 to 1.

One of the standout features of the extension is the note and song graph generator, accessible by clicking on the extension icon. Users can input JSON data that describes a song, and the extension will generate the corresponding equations. By pasting these equations into the Desmos calculator, users can listen to the song and further explore its musical properties.
