Conditional Sound Generation Using Neural Discrete Time-Frequency Representation Learning

This repository contains the code and generated sound samples of our paper "Conditional Sound Generation Using Neural Discrete Time-Frequency Representation Learning", which was accepted for MLSP 2021.

Set up environment

• Clone the repository:

  git clone https://github.com/liuxubo717/sound_generation.git
  

• Create conda environment with dependencies:

  conda create -f environment.yml -n sound_generation
  

• Activate conda environment:

  conda activate sound_generation
  

Prepare dataset

Usage

1: (Stage 1) train a multi-scale VQ-VAE to extract the Discrete T-F Representation (DTFR) of sound:

python train_vqvae.py --epoch 800

2: Extract DTFR for stage 2 training:

python extract_code.py --ckpt checkpoint/[VQ-VAE CHECKPOINT]

3: (Stage 3) train a PixelSNAIL model on the extracted DTFR of sound:

python train_pixelsnail.py --epoch 2000

4: Sample mel-spectrogram of sound from the trained PixelSNAIL model:

python mel_sample.py --vqvae checkpoint/[VQ-VAE CHECKPOINT] --bottom checkpoint/[PixelSNAIL CHECKPOINT] --label [Class ID: 0-9]

5: Synthesize waveform of sound using HiFi-GAN vocoder:

python mel2audio.py --input_mels_dor [INPUT MEL-SPECTROGRAM PATH] --output_dir [OUTPUT WAVEFORM PATH]

The trained HiFi-GAN checkpoint is provided in /hifi_gan/cp_hifigan/g_00335000

Generated samples

The generated sound samples are available at /generated_sounds
