Sound annotation with Shiny and wavesurfer
summary
Built an htmlwidget for wavesurfer that embeds the wavesurfer JS player in Shiny, adds a spectrogram view tweak and the annotator/region plugin so users can draw, resize and label segments. The app requires two inputs: a path to a folder of WAV files and a path to save annotations, shows a table marking files annotated (green) or not, and includes a region suggester that auto-draws candidate events; deployable to the cloud for collaborative labeling. Work in progress.
