How it works
1
Describe one sound
Write a focused description of the effect or cohesive ambience you need. Include the source, action, material, perspective and acoustic space, then state that you want no speech or music when cleanliness matters.
2
Set the length and format
Choose a duration between 1 and 180 seconds based on the space available in your project. Select MP3 for convenience or WAV for an editing-friendly export.
3
Generate, review and download
Generate the effect, listen for prompt accuracy and check the start, tail and background carefully. Download the best result, place it in your timeline and trim or mix it as needed.

What is Sonilo SFX?▾
Sonilo SFX is a text-to-sound-effects model that turns a written description into one generated audio effect. It can create Foley, ambience, impacts, transitions, UI cues, creature sounds and vehicle sounds.
How does Sonilo SFX work?▾
You describe the sound, choose its duration and select MP3 or WAV. The generation runs asynchronously, after which the completed audio can be reviewed and downloaded.
Does Sonilo SFX generate music, vocals or speech?▾
Sonilo SFX is intended for non-musical sound effects rather than songs, lyrics, vocals or narration. For a cleaner result, keep the prompt focused on one effect and explicitly request no speech and no music.
How long can a Sonilo SFX sound effect be?▾
You can request a duration from 1 to 180 seconds, with a default of 10 seconds. Short durations suit impacts and UI cues, while longer durations work well for rain, crowds, machinery and other sustained ambience.
What audio formats does Sonilo SFX output?▾
Sonilo SFX supports MP3 and WAV output. MP3 is convenient for previews and lightweight publishing, while WAV is generally preferable when you expect to edit, layer or process the sound.
How much does Sonilo SFX cost?▾
Pricing is based on each second of the duration you request, not per clip or per track. A three-second minimum applies, so requests shorter than three seconds still receive the minimum charge. Check the current cost estimate before generating.
Can I use Sonilo SFX sound effects commercially?▾
Commercial use depends on the current provider terms and the terms attached to your account or plan. Review those terms before using an effect in client work, advertising, monetized content, games or apps. Do not assume generation alone grants ownership or clears every third-party issue.
How can I avoid speech or music bleeding into an effect?▾
Add instructions such as no speech, no voices and no music to your prompt, then audition the full result before publishing. Check quiet sections and long tails carefully, since unwanted content can be easier to hear there.
Can Sonilo SFX match an exact moment in my video?▾
You can control the overall requested duration, but a text prompt does not provide the model with your video timeline. Generate near the target length, then place, trim and fade the effect in your editor for exact frame-level timing.
How does Sonilo SFX compare with other AI sound effect generators?▾
Sonilo SFX focuses on text-directed, single-effect generation across Foley, ambience, interfaces, creatures, vehicles and designed transitions. Its selectable 1–180 second duration and MP3 or WAV output make it suitable for both quick cues and longer sound beds.
Does Sonilo SFX have an API?▾
Yes — Sonilo SFX is available through the BudgetPixel developer API via the `POST /v1/audios/sonilo-sfx` endpoint, supporting text-to-sound-effect. Generate an API key from the developer console (available on Premium plans and above) and see the full reference at docs.budgetpixel.com.
How much does the Sonilo SFX API cost?▾
API usage is billed in credits from the same balance your plan includes, at the standard metered rate: 5 credits per second. Failed generations are never charged. You can estimate any request's exact cost with POST /v1/cost before running it.
Can I use Sonilo SFX with Claude or other AI agents (MCP)?▾
Yes — Sonilo SFX is exposed through the BudgetPixel MCP server, so Claude, Cursor, and any MCP-compatible agent can generate with it from a plain-language request. Connect your account at budgetpixel.com/mcp; generations use the same credit balance and pricing as the web studio and the API.
