## Overview Stable Audio 3 Small Music is a text-to-music model from Stability AI. It uses latent diffusion to denoise a compact music representation, then decodes it to audio. You get a ready-to-use stereo track at 44.1 kHz, which helps you draft cues without recording. ## What you can build - Short instrumental cues for video edits, ads, and social posts - Loopable background music for games, apps, and menus - Genre and mood explorations for writing sessions or storyboards - Draft music beds for podcasts and trailers (instrumental-style prompts work best) - Fast A/B variations of the same idea by changing tempo, instruments, or mood ## Inputs - A text description of the music you want, written in English. Include genre, instruments, mood, and tempo (BPM). - A target length in seconds for the generated track. The Small Music checkpoint tops out at 120 seconds. - An option to expand a short prompt into a longer, more detailed one before generation. - A setting that controls how many denoising iterations the model runs. Fewer iterations produce faster drafts. - A setting that controls how strongly the result follows your text description. ## Outputs - One downloadable audio file of the generated music, typically delivered as an MP3. - Metadata that echoes the final prompt used for generation. - A numeric seed value you can reuse to reproduce the same result later. ## Recommended settings - Start with 8 denoising iterations for this distilled Small Music checkpoint. - Keep prompt-following strength around 1.0. Higher values usually don’t help on distilled checkpoints. - Turn on prompt expansion when your prompt is a single sentence or shorter. - Use 20 to 60 seconds for quick iteration. Use up to 120 seconds for a full cue. ## Limitations - Output length is capped at 120 seconds for Stable Audio 3 Small Music. - It’s not designed for speech or voice generation. - Prompts written in English work best. Other languages often degrade quality. - Very short or vague prompts can produce generic results. Add BPM, instruments, and mix notes. - If your request implies a specific copyrighted song or a living artist’s exact style, results may be inconsistent or blocked. ## Safety & compliance - Use is governed by the Stability AI Community License. Organizations over $1M annual revenue may need an Enterprise license. - Don’t generate content that violates rights, privacy, or platform content rules. - Some deployments apply an automated safety checker and may refuse disallowed prompts. - You are responsible for how you use and distribute generated audio in your project.
