Frequently asked questions
Yes. Music you generate on Seedaudio can be downloaded and used commercially without ongoing royalties — in monetized videos, podcasts, games, ads, and client projects.
Yes — that is a core feature of Sonilo Text-to-Music. Choose any duration from 1 to 360 seconds and the music is generated to that exact length, so it lands precisely on your edit points.
No — Sonilo Text-to-Music generates pure instrumentals, which is exactly what background music needs: nothing fights your narration or dialogue. For songs with vocals, use the AI Song Generator with your own lyrics.
Any style you can describe in text: lo-fi, cinematic orchestral, upbeat pop instrumentals, ambient, acoustic, electronic, jazz and more. Mention instruments, tempo, and mood in the prompt for the closest match.
Name the genre, the mood, one or two lead instruments, and the energy level — for example "warm acoustic folk, fingerpicked guitar, hopeful, gentle build". Our prompting guide collects patterns that work well.
Yes. Generated tracks are unique to your generation rather than pulled from a shared library, and commercial use — including monetized channels — is allowed.
Tracks are generated with credits, and signup includes free credits so your first pieces cost nothing. Paid plans provide more credits for heavier production schedules; details are on the pricing page.
Tracks download as standard MP3 audio files that drop straight into any editor — Premiere, Final Cut, DaVinci Resolve, CapCut, Audacity, or your game engine.
A single track can be up to 360 seconds (6 minutes). For longer coverage, generate multiple tracks in the same described style, or set an exact duration that matches your segment so it plays through without needing a loop.
That is the AI Audio Generator, powered by Seed Audio 1.0: one prompt produces a mixed scene with multi-character dialogue, music, ambience, and sound effects together. Use BGM generation when you just need the music layer.
