Turdus migratorius. American Robin, rather than European Robin. Synthesized approximation, not a recording or an identification aid. Hear Cornell Lab’s reference ↗Arcs carry the song’s envelope and fundamental pitch; the grayscale spectrogram shows its spectrum on a log frequency scale. Visible carrier frequency is audio ÷ 200. History takes 5.2 seconds to cross the scene at 1×; this is illustrative, not physical scale. Speed changes pitch, timing, and travel together. Muting silences listening while the signal stays visible.
