# CLAP

[CLAP (Contrastive Language-Audio Pretraining)](https://huggingface.co/papers/2211.06687) is a multimodal model that combines audio data with natural language descriptions through contrastive learning.

It incorporates feature fusion and keyword-to-caption augmentation to process variable-length audio inputs and to improve performance. CLAP doesn't require task-specific training data and can learn meaningful audio representations through natural language.

You can find all the original CLAP checkpoints under the [CLAP](https://huggingface.co/collections/laion/clap-contrastive-language-audio-pretraining-65415c0b18373b607262a490) collection.

The example below demonstrates how to extract text embeddings with the [`AutoModel`] class.

<hfoptions id="usage">
<hfoption id="AutoModel">

```python
import torch

from transformers import AutoModel, AutoTokenizer


model = AutoModel.from_pretrained("laion/clap-htsat-unfused", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("laion/clap-htsat-unfused")

texts = ["the sound of a cat", "the sound of a dog", "music playing"]

inputs = tokenizer(texts, padding=True, return_tensors="pt").to(model.device)

with torch.no_grad():
    text_features = model.get_text_features(**inputs)

print(f"Text embeddings shape: {text_features.shape}")
print(f"Text embeddings: {text_features}")
```
