callsync: sychronous analysis of multiple microphones
Description
Intended to analyse recordings from multiple microphones (e.g., backpack microphones in captive setting). It allows users to align recordings even if there is non-linear drift of several minutes between them. A call detection and assignment pipeline can be used to find vocalisations and assign them to the vocalising individuals (even if the vocalisation is picked up on multiple microphones). The tracing and measurement functions allow for detailed analysis of the vocalisations and filtering of noise. Finally, the package includes a function to run spectrographic cross correlation, which can be used to compare vocalisations. It also includes multiple other functions related to analysis of vocal behaviour.
Details
The main features of the package are:
alignment and partitioning of drifting microphones using signal compression and cross correlation
call detection using an amplitude envelope
fine-scale alignment and call assignment across recordings using cross correlation and energy content
fundamental frequency tracing
analysis of the resulting traces and wav clips
The package offers functions to:
create flexible spectrograms
run spectrographic cross correlation
analyse amplitude and frequency modulation
load selection tables from Raven and Audacity
calculate performance of the detection and assignment functions
