Luscinia Description

Luscinia was developed as an accessible and Open Source software for archiving and analyzing field sound recordings (especially of animals). It incorporates an interface to a database, spectrogram measurement algorithms, sound comparison algorithms, and statistical analysis. Luscinia provides a flexible spectrogram view of sounds. The appearance of spectrograms (Fonts, tick-marks and other details) can be modified to make spectrograms suitable for publication. An ‘echo-removal’ function improves the appearance of spectrograms of field recordings. Sound playback (at different speeds), and an advanced pitch view (showing the fundamental frequency, and suitable for harmonically structured signals) are also provided. Luscinia measures 15 acoustic features of sounds at each point in the signal, and stores them in the database. The aim is to avoid repeated measurement of sounds for different analyses. Measurement uses a flexible semi-automated approach that is rapid for clean recordings, but still accurate for noisier recordings. Luscinia allows you to set up planned comparisons of certain sets of recordings - for example in tutor/tutee experiments - or analysis of large datasets from whole populations. Main features: Spectrograms of sound Database archiving of wildlife sound recordings Computational comparison of sounds, using dynamic time warping Clustering analysis Syntactical analysis of animal vocal signals Visual comparison of spectrograms
