We develop a little sound editor that looks similar to a web browser and allows editing audio in a frequency domain. The project started from a wish to have a simple application to assign text labels to an audio and just for fun.

Today it can perform simple editing operations (copy-cut-paste-overwrite), but we planning to add some fun signal processing to it and (of course) a pen allowing to draw new frequencies and get new sounds

A little demo:
