Each table below names a WAV instead of an image (spec 168). GramFrame
decodes the recording, analyses it in the browser and shows the spectrogram
as a waterfall: press ▶ and the newest sound enters at the top while the
picture slides down. The whole recording is drawn from the moment it loads,
so you can scroll through it and annotate it before playing a note
(spec 171); pause to use the annotation tools, and they scroll with the gram
when you resume. While it plays you can click the gram to pause it, or drag it to
move around — it pauses under your hand and resumes where you let go — and
the two contrast sliders on the bar lift a faint tonal out of the
background without changing a single reading. Keys on a focused player: Space
play/pause, J/L seek ±5 s, Home
restart, M mute. Recordings: Work With Sounds via Wikimedia

Each WAV has a .wav.js sidecar beside it so this page also
works when opened from the file system.
