Use the Raspberry Pi^® audio player and capture

Use Raspberry Pi to connect to and control audio input devices. The audiocapture and audioplayer objects, and the capture and play functions are only supported for code generation.

Objects

`raspi`	Connection to Raspberry Pi board
`audiocapture`	Connection between audio input device and Raspberry Pi hardware
`audioplayer`	Connection between audio output device and Raspberry Pi hardware

Functions

`capture`	Capture data from audio device connected to Raspberry Pi
`play`	Play audio from audio device connected to Raspberry Pi

Featured Examples

Audio Event Classification Using TensorFlow Lite on Raspberry Pi

Demonstrates audio event classification using a pretrained deep neural network, YAMNet, from TensorFlow™ Lite library on Raspberry Pi™. You load the TensorFlow Lite model and predict the class for the given audio frame on Raspberry Pi using a processor-in-the-loop (PIL) workflow. To generate code on Raspberry Pi, you use Embedded Coder®, MATLAB® Support Package for Raspberry Pi Hardware and Deep Learning Toolbox Interface for TensorFlow Lite. Refer to Audio Classification and yamnet classification for more details on the YAMNet model description.
