Show HN: I've made a GPU-based wavelet spectrogram tool for birdsongs

This is a client-side WebGL-based spectrogram tool that allows to edit the wavelet function (in GLSL). As a result, it supports custom wavelets.

Very very cool. Great work! But why does the title say only birdsongs, could it be used with any audio file? The examples show output from a violin's audio too.

Worth tweeting.
