A Python tool to work with any format for annotating animal sounds and bioacoustics data
crowsetta provides a Pythonic way to work with annotation formats for animal sounds and bioacoustics data. These formats are used, for example, by applications that enable users to annotate audio and/or spectrograms. Such annotations typically include the times when sound events start and stop, and labels that assign each sound to some set of classes chosen by the annotator. crowsetta has built-in support for many widely used formats, such as Audacity label tracks, Praat .TextGrid files, and Raven .txt files.
Spectrogram of the song of a Bengalese finch with syllables annotated as segments underneath. Annotations parsed by crowsetta from a file in the Praat .TextGrid format. Example song from Bengalese finch song dataset, Tachibana and Morita 2021, adapted under CC-By-4.0 License.
Spectrogram of a field recording with annotations of songs of different bird species indicated as bounding boxes. Annotations parsed by crowsetta from a file in the Raven Selection Table format. Example song from "An annotated set of audio recordings of Eastern North American birds containing frequency, time, and species information", Chronister et al., 2021, adapted under CC0 1.0 License.
Who would want to use crowsetta? Anyone that works with animal sounds or other bioacoustics data that is annotated in some way. Maybe you are a neuroscientist trying to figure out how songbirds learn their song, or why mice emit ultrasonic calls. Or maybe you're an ecologist studying dialects of finches distributed across Asia, or maybe you are a linguist studying accents in the Caribbean, or a speech pathologist looking for phonetic changes that indicate early onset Alzheimer's disease. crowsetta makes it easier for you to work with your annotations in Python, regardless of the format.
annot = crowsetta.Transcriber(format='format').from_file('annotations.ext')
