Model overview

musicgen-fine-tuner is a Cog implementation of the MusicGen model, a straightforward and manageable model for music generation. Developed by the Meta team, MusicGen is a simple and controllable model that can generate diverse music without requiring a self-supervised semantic representation like MusicLM. The musicgen-fine-tuner allows users to refine the MusicGen model using their own datasets, enabling them to customize the generated music to their specific needs.

Model inputs and outputs

The musicgen-fine-tuner model takes several inputs to generate music, including a prompt describing the desired music, an optional input audio file to influence the melody, and various configuration parameters like duration, temperature, and continuation options. The model outputs a WAV or MP3 audio file containing the generated music.

Inputs

Prompt: A description of the music you want to generate.
Input Audio: An audio file that will influence the generated music. The model can either continue the melody of the input audio or mimic its overall style.
Duration: The duration of the generated audio in seconds.
Continuation: Whether the generated music should continue the input audio's melody or mimic its overall style.
Continuation Start/End: The start and end times of the input audio to use for continuation.
Multi-Band Diffusion: Whether to use multi-band diffusion when decoding the EnCodec tokens (only works with non-stereo models).
Normalization Strategy: The strategy for normalizing the output audio.
Temperature: Controls the "conservativeness" of the sampling process, with higher values producing more diverse outputs.
Classifier Free Guidance: Increases the influence of inputs on the output, producing lower-variance outputs that adhere more closely to the inputs.
