waveform image
Takes an audio or video file (up to 24 MB) and returns its waveform as a PNG image with chosen width, height, wave colour and background colour, mono or one lane per channel, optionally on a logarithmic scale that makes quiet speech visible. Rendered locally with ffmpeg; the image comes back inline as base64 along with duration and size. Nothing leaves this machine. Fixed price per call.
