internal

Provides an all-in-one solution for automatic classification of
sound events using convolutional neural networks (CNN). The main purpose
is to provide a sound classification workflow, from annotating sound events
in recordings to training and automating model usage in real-life
situations. Using the package requires a pre-compiled collection of
recordings with sound events of interest and it can be employed for:
1) Annotation: create a database of annotated recordings,
2) Training: prepare train data from annotated recordings and fit CNN models,
3) Classification: automate the use of the fitted model for classifying
new recordings. By using automatic feature selection and a user-friendly GUI
for managing data and training/deploying models, this package is intended
to be used by a broad audience as it does not require specific expertise in
statistics, programming or sound analysis. Please refer to the vignette for
further information.
