waveform

Audio waveform display component

by Martyn Ranyard

About

A little widget for displaying a recorded waveform.

Expects a slice of int32 samples, and displays them in a familiar way. Doesn’t “curve” the waveform, simply plots it.

Can just display data 1 sample per pixel or resample data (uses disintegration/imaging to do nearest neighbour image resampling) to the width of the widget.

Default is themable, Colors are overridable. Background can be removed or not.
