Audio Labeler

Define and visualize ground-truth labels

Description

The Audio Labeler app enables you to label ground-truth data at both the region level and file level.

Using the app, you can:

Create label definitions for consistent and fast labeling.
Visualize the time-domain waveform during playback.
Interactively specify labels at the file level and region level. You can specify regions by drawing directly on the time-domain waveform.
Record new audio to add to your dataset.

The app exports data as a labeledSignalSet object. You can use labeledSignalSet to train a network, classifier, or analyze data and report statistics.
