Overview

Concrete tool for running an interactive Gradio web demo of the MAGNeT text-to-music and text-to-sound generation model.

Description

MagnetApp is a Gradio web application that provides an interactive interface for the MAGNeT model. It supports text-conditioned generation for both music and environmental sound, with configurable parameters including model variant selection (small/medium, 10s/30s), temperature, top-k/top-p sampling, CFG coefficients, decoding steps, and span arrangement.

Usage

Run this application to demonstrate MAGNeT's text-to-music and text-to-sound generation capabilities through a web browser interface.
