MuQ & MuQ-MuLan

Static Badge

This is the official repository for the paper "MuQ: Self-Supervised Music Representation Learning with Mel Residual Vector Quantization". For more detailed information, we strongly recommend referring to https://github.com/tencent-ailab/MuQ and the paper.

In this repo, the following models are released:

MuQ(see this link): A large music foundation model pre-trained via Self-Supervised Learning (SSL), achieving SOTA in various MIR tasks.
MuQ-MuLan(see this link): A music-text joint embedding model trained via contrastive learning, supporting both English and Chinese texts.

Usage

To begin with, please use pip to install the official muq lib, and ensure that your python>=3.8:

pip3 install muq

To extract music audio features using MuQ:

python

import torch, librosa
from muq import MuQ

device = 'cuda'
wav, sr = librosa.load("path/to/music_audio.wav", sr = 24000)
wavs = torch.tensor(wav).unsqueeze(0).to(device) 

# This will automatically fetch the checkpoint from huggingface
muq = MuQ.from_pretrained("OpenMuQ/MuQ-large-msd-iter")
muq = muq.to(device).eval()

with torch.no_grad():
    output = muq(wavs, output_hidden_states=True)

print('Total number of layers: ', len(output.hidden_states))
print('Feature shape: ', output.last_hidden_state.shape)

Using MuQ-MuLan to extract the music and text embeddings and calculate the similarity:

python

import torch, librosa
from muq import MuQMuLan

# This will automatically fetch checkpoints from huggingface
device = 'cuda'
mulan = MuQMuLan.from_pretrained("OpenMuQ/MuQ-MuLan-large")
mulan = mulan.to(device).eval()

# Extract music embeddings
wav, sr = librosa.load("path/to/music_audio.wav", sr = 24000)
wavs = torch.tensor(wav).unsqueeze(0).to(device) 
with torch.no_grad():
    audio_embeds = mulan(wavs = wavs) 

# Extract text embeddings (texts can be in English or Chinese)
texts = ["classical genres, hopeful mood, piano.", "一首适合海边风景的小提琴曲，节奏欢快"]
with torch.no_grad():
    text_embeds = mulan(texts = texts)

# Calculate dot product similarity
sim = mulan.calc_similarity(audio_embeds, text_embeds)
print(sim)

Model Checkpoints

Model Name	Parameters	Data	HuggingFace🤗
MuQ	~300M	MSD dataset	OpenMuQ/MuQ-large-msd-iter
MuQ-MuLan	~700M	music-text pairs	OpenMuQ/MuQ-MuLan-large

Note: Please note that the open-sourced MuQ was trained on the Million Song Dataset. Due to differences in dataset size, the open-sourced model may not achieve the same level of performance as reported in the paper.
