Topics
- Measure and Manage Impulse Responses
Capture and analyze impulse response (IR) measurements by using the Impulse Response Measurer.
- Create an App to Play and Visualize Audio Files
Create an app in App Designer to play and visualize audio files.
- Surround Sound Matrix Encoding and Decoding
This example shows how to generate a stereo signal from a multichannel audio signal using matrix encoding, and how to recover the original channels from the stereo mix using matrix decoding.
