pitch trace exploration tool


notes and caveats

Please contact Robert M Ochshorn or file issues on Github with bug reports and feature requests.

While the Ellis pitch-tracking algorithm that Drift uses is state-of-the-art, and works well even on noisy recordings, some errors in pitch-tracking are inevitable.

See “Twelve Prosodic Measures” in “Beyond Poet Voice: Sampling the Non-Performance Styles of 100 American Poets” for ideas of how to analyze the pitch and timing data Drift provides.
