You can produce a full song with AI-written lyrics, a pure instrumental, or a short loop — all from a written prompt plus a handful of musical controls. The audio comes back in the gallery next to your images and videos and can be exported as standard audio files. Audio runs on the Sogni Supernet using two model families: - **MiniMax Music 3** — the premium composer. An autoregressive model that writes the song in order, with the most realistic vocals, strongest lyric adherence, and true verse–chorus structure. It sings in many languages, handles duets, choirs, rap, and a cappella, and composes its own ending — the duration you set is a ceiling of up to 5 minutes. Describe tempo and key in your prompt; Music 3 has no separate BPM, key, or time-signature controls. - **ACE-Step** — the fast workhorse family. Turbo and SFT builds with fine musician controls (exact BPM, key/scale, time signature, up to 10 minutes) at a fraction of the cost. Ideal for drafts, loops, and tracks that must hit an exact tempo grid. ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#two-modes)Two modes ### [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#song-with-lyrics)Song with Lyrics A full song with AI-written lyrics structured into sections (verse, chorus, bridge, outro). Studio's LLM lyrics generator (the **AI Lyrics Generator** tool) produces: - **Section-based lyrics** with vocal modifiers (e.g., "soft", "belted", "spoken"). - **BPM, key, scale, time signature** suggestions matched to the lyrics' mood. - **Duration** for the full track. You can edit any of the generated fields before rendering — rewrite a chorus line, change the key, shift the BPM. Or write the lyrics yourself and let the model handle the music. ### [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#instrumental)Instrumental Music only — no vocals, no lyrics. Set BPM, key, scale, time signature, and a style prompt; ACE-Step composes around those constraints. Useful for: - Background tracks for [Sound to Video](https://docs.sogni.ai/sogni-create/studio/creating-videos/video-create-mode/sound-to-video/). - Looping ambient beds. - Reference tracks for your own composition work. ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#musical-controls)Musical controls Available across both modes: - **Prompt / Style** — the descriptive direction ("dark synthwave with analog warmth and a driving bassline"). - **Style Presets** — around a hundred curated presets across genres, eras, moods, and production styles, plus a Custom field for your own style text. Stack with your prompt for finer direction. - **BPM** — tempo. Auto-suggested per style, freely editable. - **Key & Scale** — musical tonality (e.g., C minor, G Lydian). - **Time Signature** — beats per measure. Defaults to 4/4; supports 3/4, 6/8, 5/4, 7/8, etc. - **Duration** — total track length. Longer durations cost more Spark. ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#how-to-use-it)How to use it 1. **Switch Create mode to Audio.** 2. **Pick a mode** — Song with Lyrics or Instrumental. 3. **For lyrics:** click **Generate Lyrics** to have the AI draft a full song, or write your own in the lyrics field. 4. **Pick a style preset** or write your own style prompt. 5. **Tune BPM, key, scale, time signature, duration** as needed. 6. **Generate.** The job lands in the queue. Long tracks render in pieces and stream into the gallery as they're ready. ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#pairing-audio-with-video)Pairing audio with video Studio's audio tracks plug straight into the video workflows: [Sound to Video— let your generated audio drive video motion.](https://docs.sogni.ai/sogni-create/studio/creating-videos/video-create-mode/sound-to-video/)[Clip Mixer— paste a generated track onto a stitched video timeline.](https://docs.sogni.ai/sogni-create/studio/creating-videos/clip-mixer/) ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#screenwriter-cinematic-prompt-expansion)Screenwriter: cinematic prompt expansion For video work that pairs with audio, Studio's chat panel includes a **Screenwriter** tool that takes a short scene description and expands it into a cinematic, LTX-tuned video prompt. Use it as the prompt input for video clips that match the mood of your generated music. See [Chat & creative tools](https://docs.sogni.ai/sogni-create/studio/chat-and-tools/). ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#tips)Tips - **Start with a preset.** The genre presets encode BPM, key, instrumentation, and production style as one click. Tune from there. - **Lock BPM before generating multi-track sets.** If you want several tracks for the same project, lock the BPM and key so they layer cleanly. - **Iterate on lyrics, not music.** Lyrics edits are cheap (you don't re-render the song until you generate); music re-rolls are full renders. - **Use 4/4 unless you have a reason not to.** ACE-Step is strongest in 4/4; odd time signatures work but with more variance. ## [#](https://docs.sogni.ai/sogni-create/studio/creating-audio/#see-also)See also [Sound to Video— drive video from audio you generate here.](https://docs.sogni.ai/sogni-create/studio/creating-videos/video-create-mode/sound-to-video/)[Chat & Creative Tools— Screenwriter and other LLM tools.](https://docs.sogni.ai/sogni-create/studio/chat-and-tools/)[Models— ACE-Step and the full model lineup.](https://docs.sogni.ai/sogni-create/studio/models/)
