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.
