Signal Labeler

Label signal attributes, regions, and points of interest, and extract features

Since R2019a

Description

The Signal Labeler app is an interactive tool that enables you to label signals for analysis or for use in machine learning and deep learning applications. Using Signal Labeler, you can:

Label signal attributes, regions, and points of interest
Use logical, categorical, numerical, or string-valued labels
Automatically label signal peaks or apply custom labeling functions
Import, label, and play audio signals
Use frequency and time-frequency views to aid labeling
Generate attribute and region-of-interest (ROI) labels from signal features
Add, edit, and delete labels or sublabels
Display selected subsets of signals and labels

Signal Labeler saves data as labeledSignalSet objects. You can use labeledSignalSet objects to train a network, classifier, or analyze data and report statistics.

For more information, see Using Signal Labeler App.

You need an Audio Toolbox™ license to label audio signals.
