Unseen Creatures · The Mouse's Song

A male mouse's ultrasonic song at 30-110 kHz, 32 times slower: several syllable types, repeated phrases, and a song built from phrases that starts again. The shapes of the syllables and the order of the phrases are representative. Not a recording: a representative synthesis built from the measurements in the sources. There is no claim of any effect.
