Model

TL;DR

CLAP is to audio what CLIP is to image. This is an improved CLAP checkpoint, specifically trained on music.

Description

CLAP (Contrastive Language-Audio Pretraining) is a neural network trained on a variety of (audio, text) pairs. It can be instructed in to predict the most relevant text snippet, given an audio, without directly optimizing for the task. The CLAP model uses a SWINTransformer to get audio features from a log-Mel spectrogram input, and a RoBERTa model to get text features. Both the text and audio features are then projected to a latent space with identical dimension. The dot product between the projected audio and text features is then used as a similar score.

Usage

You can use this model for zero shot audio classification or extracting audio and/or textual features.

Uses

Perform zero-shot audio classification

Using pipeline

from datasets import load_dataset
from transformers import pipeline

dataset = load_dataset("ashraq/esc50")
audio = dataset["train"]["audio"][-1]["array"]

audio_classifier = pipeline(task="zero-shot-audio-classification", model="laion/larger_clap_music")
output = audio_classifier(audio, candidate_labels=["Sound of a dog", "Sound of vaccum cleaner"])
print(output)
>>> [{"score": 0.999, "label": "Sound of a dog"}, {"score": 0.001, "label": "Sound of vaccum cleaner"}]

Run the model:

You can also get the audio and text embeddings using ClapModel

Run the model on CPU:

from datasets import load_dataset
from transformers import ClapModel, ClapProcessor

librispeech_dummy = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")
audio_sample = librispeech_dummy[0]

model = ClapModel.from_pretrained("laion/larger_clap_music")
processor = ClapProcessor.from_pretrained("laion/larger_clap_music")

inputs = processor(audios=audio_sample["audio"]["array"], return_tensors="pt")
audio_embed = model.get_audio_features(**inputs)
