Audio Classification
Learn to classify audio using machine learning, covering feature extraction, audio-specific transformers, and zero-shot classification.

The play
- Mel-Spectrogram Feature ExtractionExtract mel-spectrogram features from audio files using Librosa. Visualize the spectrogram and understand its parameters.
- Training with Audio-Specific Transformers (AST)Train an Audio Spectrogram Transformer (AST) model for audio classification using PyTorch. Prepare your dataset and fine-tune the pre-trained AST model.
- Zero-Shot Audio Classification with CLAPPerform zero-shot audio classification using the CLAP model. Encode audio and text descriptions, then calculate similarity scores to classify audio without training.
Starter code
Start by extracting mel-spectrogram features from a sample audio file. Then, explore pre-trained audio classification models like AST and CLAP.
