Draw Tones!

[ Caleb ] - 2018-08-19 - [ audio clojurescript ]


A few years ago I started a test project that would allow a user to have fine grained control over a tone by drawing the frequency and volume envelopes themselves. I've since come back to the project and added a little polish. You can find the app below.

Skip the words and jump to it!

Some details

The idea is simple (and if you follow the link you'll see the implementation is even simpler), what if a creator could just draw what they wanted their sound to be? This project emerged out of that idea, and basic follows the vision. Albeit a rather simple more proof-of-concept version of that vision. I won't go into details here about how this was done (as it's actually rather simple) becuase the entire source, a little under 200 lines with some javascript glue, is available on github.

Still not convinced? Check out this sweet screenshot showing a tone with an approximately gaussian volume envelope and a chirping frequency.

Notice that the above interface is plain:

Now go ahead and create your own sounds! Please share anything cool you come up with!

This project was created with clojurescript and the sablono library. You can see the entire file here.
