# 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.
