What Is Riffusion and How It Works (2025 Guide)

Riffusion is an open-source AI tool that generates music from text prompts by converting them into spectrograms, which are then transformed into sound. Unlike traditional music production,

Riffusion uses AI-driven models like Stable Diffusion to create unique audio clips. AI in music production has grown significantly in recent years, with models like Riffusion providing new avenues for creativity. This guide explains how Riffusion works and its applications for creators in 2025.

What Is Riffusion and Why Was It Created?

Riffusion is an open-source AI tool that converts text prompts into music using diffusion models. It was created to explore how AI can generate musical compositions from textual descriptions, utilizing the same technology that powers image generation, like Stable Diffusion.

Riffusion emerged from the intersection of image-generation AI and music, designed to tackle how we can represent sound visually through spectrograms. Instead of working directly with audio files,

Riffusion first creates a visual representation (spectrogram) of sound, which is then transformed back into audio. This process is similar to what image-generation models do when creating visuals from text.

For instance, you could input a text prompt like “soft jazz with rain in the background” into Riffusion, and it will generate a unique audio clip that fits the description. This model showcases the potential of text-to-music AI in a way that’s both innovative and user-friendly. (Source: Riffusion GitHub Repo)

How Does Riffusion Turn Text into Music?

Riffusion works by translating your text prompts into spectrograms, which are visual representations of sound.

It then uses a diffusion model to iteratively refine these spectrograms before converting them into audio.

Let’s break it down:

1. You provide a detailed text prompt (like “lo-fi jazz with a smooth piano riff”).

2. Generate Spectrogram: The AI uses Stable Diffusion’s image-generation technology to map that text into a spectrogram (a visual representation of frequencies). The AI uses Stable Diffusion’s image-generation technology to map that text into a spectrogram.

3. Refining Process: Riffusion applies a noise-reduction process (diffusion) to create more musicality and refine the sound.

4. Conversion to Audio: Once the spectrogram is ready, the model uses the inverse Fourier transform to convert the image into sound.

Snippet Bait – Step-by-Step Process:

• Step 1: Text → Spectrogram.

• Step 2: The Diffusion model refines the spectrogram.

• Step 3: Spectrogram → Audio output.

If you type in “ambient sound with ocean waves and birds chirping,” Riffusion will create a sound clip that combines these elements, giving you an atmospheric track. (Source: Stable Diffusion – arXiv)

Many users might wonder if they can use the music they create in videos, commercials, or other content for profit. Riffusion’s open-source license gives creators the freedom to sell their AI-generated tracks, as long as they provide proper attribution to the creators of the tool.

Some independent artists use Riffusion to generate background music for their YouTube videos, while others integrate it into larger compositions. Because it’s open-source, they can use the output for commercial purposes without issue.

How Do Prompts and Seeds Affect the Output?

The text prompts you provide and the “seed” number you choose directly influence Riffusion’s output, affecting genre, mood, and instrument selection.

When you enter a text prompt into Riffusion, the AI interprets it to generate a corresponding sound. However, the seed (a random number) can be adjusted to alter the music, producing varied outputs for the same prompt.

This level of customization makes Riffusion especially interesting for creators looking for unique results with every interaction.

How Prompts Influence Music Generation

• Descriptive Prompts: The more detailed your prompt, the more specific the output. For instance, “chill beats with a jazzy piano” will give a different result than just “chill beats.”

• General Prompts: Vague inputs can lead to more generic outputs, such as a random, simple melody.

How Seeds Influence Variation

• Same Prompt, Different Seeds: By adjusting the seed, you change how the AI interprets your prompt. Two different seed numbers for “lo-fi jazz” might generate two entirely different sound profiles.

A prompt like “uplifting piano melody with light percussion” with seed one may produce a soft, classical-sounding piece. In contrast, seed 42 could generate a jazzy, rhythmic variation with more complex percussion.
