UniMus Project: OpenJMLA

Music tagging is a task to predict the tags of music recordings. However, previous music tagging research primarily focuses on close-set music tagging tasks which can not be generalized to new tags. In this work, we propose a zero-shot music tagging system modeled by a joint music and language attention (JMLA) model to address the open-set music tagging problem. The JMLA model consists of an audio encoder modeled by a pretrained masked autoencoder and a decoder modeled by a Falcon7B. We introduce preceiver resampler to convert arbitrary length audio into fixed length embeddings. We introduce dense attention connections between encoder and decoder layers to improve the information flow between the encoder and decoder layers. We collect a large-scale music and description dataset from the internet. We propose to use ChatGPT to convert the raw descriptions into formalized and diverse descriptions to train the JMLA models. Our proposed JMLA system achieves a zero-shot audio tagging accuracy of 64.82% on the GTZAN dataset, outperforming previous zero-shot systems and achieves comparable results to previous systems on the FMA and the MagnaTagATune datasets.

Quickstart

Below, we provide simple examples to show how to use OpenJMLA with 🤗 Transformers.

🤗 Transformers

To use OpenJMLA for the inference, all you need to do is to input a few lines of codes as demonstrated below.

from transformers import AutoModel, AutoTokenizer
import torch
import numpy as np

model = AutoModel.from_pretrained('UniMus/OpenJMLA', trust_remote_code=True)
device = model.device
# sample rate: 16k
music_path = '/path/to/music.wav'
# 1. get logmelspectrogram
# get the file wav_to_mel.py from https://github.com/taugastcn/SpectPrompt.git
from wav_to_mel import wav_to_mel
lms = wav_to_mel(music_path)

import os
from torch.nn.utils.rnn import pad_sequence
import random
# get the file transforms.py from https://github.com/taugastcn/SpectPrompt.git
from transforms import Normalize, SpecRandomCrop, SpecPadding, SpecRepeat
transforms = [ Normalize(-4.5, 4.5), SpecRandomCrop(target_len=2992), SpecPadding(target_len=2992), SpecRepeat() ]
lms = lms.numpy()
for trans in transforms:
    lms = trans(lms)

# 2. template of input
input_dic = dict()
input_dic['filenames'] = [music_path.split('/')[-1]]
input_dic['ans_crds'] = [0]
input_dic['audio_crds'] = [0]
input_dic['attention_mask'] = torch.tensor([[1, 1, 1, 1, 1]]).to(device)
input_dic['input_ids'] = torch.tensor([[1, 694, 5777, 683, 13]]).to(device)
input_dic['spectrogram'] = torch.from_numpy(lms).unsqueez(dim=0).to(device)
# 3. generation
model.eval()
gen_ids = model.forward_test(input)
gen_text = model.neck.tokenizer.batch_decode(gen_ids.clip(0))
# 4. Post-processing
# Given that the training data may contain biases, the generated texts might need some straightforward post-processing to ensure accuracy.
# In future versions, we will enhance the quality of the data.
gen_text = gen_text.split('<s>')[-1].split('\n')[0].strip()
gen_text = gen_text.replace(' in Chinese','')
gen_text = gen_text.replace(' Chinese','')
print(gen_text)

Example

music:

caption:

Instruments: Vocals, piano, strings Genre: pop Theme: Heartbreak. Mood: Melancholy. Era: Contemporary. Tempo: Fast Best scene: A small, dimly lit bar. The melancholy mood of this song will complement the stage-inspired melody.
