CLAP

CLAP (Contrastive Language-Audio Pretraining) is a model that learns acoustic concepts from natural language supervision and enables “Zero-Shot” inference. The model has been extensively evaluated in 26 audio downstream tasks achieving SoTA in several of them including classification, retrieval, and captioning.

Setup

First, install python 3.8 or higher (3.11 recommended). Then, install CLAP using either of the following:

# Install pypi pacakge
pip install msclap

# Or Install latest (unstable) git source
pip install git+https://github.com/microsoft/CLAP.git

NEW CLAP weights

Download CLAP weights: versions 2022, 2023, and clapcap: Pretrained Model [Zenodo]

clapcap is the audio captioning model that uses the 2023 encoders.

Usage

In CLAP\src\:

• Zero-Shot Classification and Retrieval

from msclap import CLAP

# Load model (Choose between versions '2022' or '2023')
clap_model = CLAP("<PATH TO WEIGHTS>", version = '2023', 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 between audio and text embeddings 
similarities = clap_model.compute_similarity(audio_embeddings, text_embeddings)

• Audio Captioning

from msclap import CLAP

# Load model (Choose version 'clapcap')
clap_model = CLAP("<PATH TO WEIGHTS>", version = 'clapcap', use_cuda=False)

# Generate audio captions
captions = clap_model.generate_caption(file_paths: List[str])

Examples

Take a look at examples for usage examples.

To run Zero-Shot Classification on the ESC50 dataset try the following:

> cd src && python zero_shot_classification.py

Output (version 2023)

ESC50 Accuracy: 93.9%
