Audio
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
Featured Examples
Audio Pitch Shift Using Audio Capture Playback
Shift the pitch of an audio signal on Raspberry Pi® hardware using audio capture and playback.
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.
