Audio to image

Drop in a track and take away a picture of it — vector SVG, or PNG / JPEG at whatever size the thing you're publishing to demands. The amplitude controls are the part worth knowing about: a mastered track drawn on a linear scale is a solid block, because everything sits within a few dB of full scale. Draw it in dBFS instead and the shape comes back. RMS reads loudness and stays steady; peak keeps the transients. Your audio is decoded in the page and never uploaded.
