## Content

## Introduction

Riffusion (hobby) is a pioneering open-source project that leverages stable diffusion for real-time music and audio generation. Developed in Python, it transforms textual prompts into unique soundscapes by manipulating spectrogram images. This repository serves as the core for Riffusion's image and audio processing, offering a diffusion pipeline that combines prompt interpolation with image conditioning. It also provides utilities for converting between spectrogram images and audio clips, an interactive Streamlit application, and a Flask server for model inference via an API. Please note, this project is no longer actively maintained.

## Installation

To get started with Riffusion, it is highly recommended to set up a virtual Python environment. The project has been tested with Python 3.9 and 3.10.

First, create and activate a virtual environment (e.g., using `conda`):

bash
conda create --name riffusion python=3.9
conda activate riffusion


Next, install the required Python dependencies:

bash
python -m pip install -r requirements.txt


For handling audio formats beyond WAV, `ffmpeg` is necessary. Install it using your system's package manager or `conda`:

bash
sudo apt-get install ffmpeg          # Linux
brew install ffmpeg                  # macOS
conda install -c conda-forge ffmpeg  # Conda


## Examples

Riffusion offers several ways to interact with its capabilities, from a command-line interface to an interactive web app and an API server.

### Command-Line Interface (CLI)

The CLI allows for common tasks, such as converting images to audio:

bash
python -m riffusion.cli image-to-audio --image spectrogram_image.png --audio clip.wav


### Riffusion Playground (Streamlit App)

Explore Riffusion interactively using its Streamlit app:

bash
python -m riffusion.streamlit.playground


Access the playground in your browser at `http://127.0.0.1:8501/`.

### Model Server (Flask API)

Run Riffusion as a Flask server to provide inference via an API, enabling integration with other applications, such as the Riffusion web app:

bash
python -m riffusion.server --host 127.00.1 --port 3013


The model endpoint is available at `http://127.0.0.1:3013/run_inference` via POST request.

## Why Use It

Riffusion stands out for its innovative application of stable diffusion to the domain of real-time music generation. It provides a unique platform for artists, developers, and researchers to experiment with AI-driven audio synthesis, offering granular control over soundscapes through prompt engineering and image conditioning. Despite its maintenance status, it remains a valuable resource for understanding and exploring the intersection of AI, audio processing, and creative expression, pushing the boundaries of what's possible with generative models in music.
