Msanii: High Fidelity Music Synthesis on a Shoestring Budget

A novel diffusion-based model for synthesizing long-context, high-fidelity music efficiently.

Abstract

In this paper, we present Msanii, a novel diffusion-based model for synthesizing long-context, high-fidelity music efficiently. Our model combines the expressiveness of mel spectrograms, the generative capabilities of diffusion models, and the vocoding capabilities of neural vocoders. We demonstrate the effectiveness of Msanii by synthesizing tens of seconds (190 seconds) of stereo music at high sample rates (44.1 kHz) without the use of concatenative synthesis, cascading architectures, or compression techniques. To the best of our knowledge, this is the first work to successfully employ a diffusion-based model for synthesizing such long music samples at high sample rates. Our demo can be found here and our code here.

Setup

Setup your virtual environment using conda or venv.

Install package from git

    pip install -q git+https://github.com/Kinyugo/msanii.git

Install package in edit mode

    git clone https://github.com/Kinyugo/msanii.git
    cd msanii

Training

Notebook

CLI

To train via CLI you need to define a config file. Check for sample config files within the conf directory.

    wandb login
    python -m msanii.scripts.training <path-to-your-config.yml-file>

Inference

Notebook

CLI

Msanii supports the following inference tasks:

• sampling
• audio2audio
• interpolation
• inpainting
• outpainting

Each task requires a different config file. Check conf directory for samples.

    gdown 1G9kF0r5vxYXPSdSuv4t3GR-sBO8xGFCe # model checkpoint
    python -m msanii.scripts.inference <task> <path-to-your-config.yml-file>
