CLAP

CLAP (Contrastive Language-Audio Pretraining) is a neural network model that learns acoustic concepts from natural language supervision. It achieves SoTA in “Zero-Shot” classification, Audio-Text & Text-Audio Retrieval, and in some datasets when finetuned.

Setup

You are required to just install the dependencies: pip install -r requirements.txt using Python 3 to get started.

If you have conda installed, you can run the following:

git clone https://github.com/microsoft/CLAP.git && \
cd CLAP && \
conda create -n clap python=3.8 && \
conda activate clap && \
pip install -r requirements.txt

CLAP weights

Usage

Please take a look at src/examples for usage examples.

• Load model

from src import CLAP 

clap_model = CLAP("<PATH TO WEIGHTS>", use_cuda=False)

• Extract text embeddings

text_embeddings = clap_model.get_text_embeddings(class_labels: List[str])

• Extract audio embeddings

audio_embeddings = clap_model.get_audio_embeddings(file_paths: List[str])

• Compute similarity

sim = clap_model.compute_similarity(audio_embeddings, text_embeddings)

Examples

To run zero-shot evaluation on the ESC50 dataset or a single audio file from ESC50, check CLAP\src\. For zero-shot evaluation on the ESC50 dataset:

> cd src && python zero_shot_classification.py

Output

ESC50 Accuracy: 82.6%
