How Sonauto Works
Sonauto writes, arranges, and produces original songs from plain text. Type what you want to hear and get back a finished track — no studio gear or music skills required.
Step 1: Describe the music you want
Write a prompt with genre, mood, tempo, and style — for example, 'upbeat synthwave with heavy bass and 80s drums'. Sonauto interprets it and generates music tailored to your vision.
Step 2: Sonauto creates the full track
Your prompt becomes a complete original song — composition, arrangement, production, all in one pass. The AI handles everything from melody to final mix.
Step 3: Refine and download
Preview the result. Tweak your prompt and regenerate if something's off. Download the finished track when it sounds right — yours to use with no restrictions.
Why Producers Choose Sonauto
Sonauto combines free unlimited song generation with pro-grade tools: audio inpainting, stem separation, BPM and key control, and melody conditioning — all designed for real music production.
Free Unlimited Generation — No Daily Caps
Sonauto's consumer tier is free with no daily or monthly generation limits. Create as many songs as you want, iterate as much as you need, and never hit a paywall just to keep working on your music.
Rewrite Any Section — Audio Inpainting
Select a specific part of your song — a verse, a chorus, a bridge — and regenerate only that section. The rest of the track stays intact. This is surgical editing for AI music that no other free tool offers at this level.
Stem Separation for DAW Export
Separate your generated tracks into individual stems: vocals, drums, bass, and other instruments. Export them as high-quality audio files and import directly into Ableton, FL Studio, or Logic Pro for further production.
Extend and Transition Tools
Extend short audio clips into full-length songs while maintaining stylistic consistency. Generate smooth transitions between two different audio clips — useful for creating song structures, DJ bridges, or soundtrack segues.
Melody Conditioning With MIDI or Audio
Upload a MIDI file or audio clip to guide Sonauto's generation. The model conditions its output on your musical input, following your chord progression, melodic contour, or rhythmic pattern for results that match your vision.
Full Ownership and Commercial Rights
You own everything you create with Sonauto. Commercial use is included at all tiers — use your songs in YouTube videos, streaming releases, games, ads, and client projects without paying additional licensing fees.
What Creators Say About Sonauto
From producers who need surgical editing tools to game developers shipping with free commercial licenses — here is how people use Sonauto's unique feature set.
"The inpainting feature is what sold me. Every other AI music tool makes you regenerate the whole song if you do not like one section. Sonauto lets me rewrite just the chorus while keeping the verse I already love."
"I generated my entire game soundtrack with Sonauto's free tier. Full commercial rights mean I can ship the game without worrying about music licensing. That saved me at least $2,000 in composer fees."
"Stem separation + DAW export is the combo I use on every track. Generate in Sonauto, split into stems, drop into Ableton, and build a completely new arrangement around the vocal. It is a full remix pipeline in one tool."

"I upload MIDI sketches of my chord progressions and Sonauto generates realistic orchestral arrangements around them. It is like having a virtual arranger that turns my piano sketches into production-ready demos."
"The transition tool is perfect for stitching together podcast segments. I generate smooth audio bridges between interview clips and my outro music. No more awkward silence or jarring cuts."
"I go through a lot of background music for daily uploads. Sonauto's unlimited free tier means I never run out of options. If a track is not quite right, I inpaint the weak section instead of starting over."

Sonauto FAQ
Common questions about Sonauto's free unlimited generation, inpainting, stem separation, commercial licensing, and API access.
Is Sonauto really free and unlimited?
Yes. Sonauto's consumer tier is free with no daily or monthly generation caps. You can create as many songs as you want without hitting a limit or needing to upgrade. API usage has separate pricing.
What is audio inpainting?
Inpainting lets you select a specific section of a generated song — like a verse or chorus — and regenerate only that part. The rest of the track stays unchanged. You describe what you want instead, and Sonauto rewrites just that section.
Can I separate stems from my generated tracks?
Yes. Sonauto can separate your songs into individual stems: vocals, drums, bass, and other instruments. Each stem can be downloaded as a separate audio file for use in a DAW or remix project.
How does melody conditioning work?
Upload a MIDI file or audio clip as a reference, and Sonauto conditions its generation on your musical input. The output follows your chord progression, melodic contour, or rhythmic pattern, producing results that match your intended musical direction.
Can I use Sonauto songs commercially?
Yes. You own everything you create with Sonauto. Commercial use is included at all tiers — free and paid. Use your songs in YouTube videos, streaming releases, games, ads, and client projects without additional fees.
How many style tags does Sonauto support?
Sonauto v3 supports over 4,100 style tags for precise genre targeting. You can combine multiple tags (e.g., 'synthwave' + 'dark' + 'aggressive') for highly specific production outcomes.
Can I extend a short clip into a full song?
Yes. The extend tool grows short audio clips into full-length arrangements. Each extension maintains stylistic consistency with the original clip, making it useful for building full song structures from short hooks or ideas.
Does Sonauto have an API?
Yes. Sonauto offers a developer API with endpoints for generation, inpainting, extension, transition generation, and stem separation. API plans start at $11/month for 20,000 credits.
How does Sonauto compare to Suno or Udio?
Sonauto differentiates with free unlimited generation, audio inpainting (surgical section rewriting), stem separation for DAW export, melody conditioning via MIDI/audio upload, and granular style tag targeting with 4,100+ options.
What is Sonauto best for?
Sonauto is best for producers, remix artists, and creators who want more control over their AI-generated music than a simple prompt-and-generate workflow. Its inpainting, stem separation, and melody conditioning tools make it ideal for iterative production, remixing, game audio, and commercial content creation where full ownership matters.
