Extract Audio Features

Streamline audio feature extraction in the Live Editor

Since R2020a

Description

The Extract Audio Features task enables you to configure an optimized feature extraction pipeline by selecting features and parameters graphically. You can reuse the output from Extract Audio Features to apply feature extraction to entire data sets. The task automatically generates MATLAB® code for your live script.

Using this task, you can:

  • Extract features of audio signals common to machine learning and deep learning workflows.

  • Create a feature extraction object for use with large data sets.

  • Visualize extracted audio features.

To learn more about interactive tasks in live scripts, see Add Interactive Tasks to a Live Script.
