Pixazo AI SFX Generator vs Sonilo

Pixazo AI SFX Generator creates short sound effects from text prompts and can also match audio to an uploaded video clip. Text-to-audio uses Mirelo SFX, while video-to-audio uses MMAudio. It can produce one-shot effects, foley, game and UI sounds, and loopable ambiences, with results downloadable as WAV files. Generation and downloads happen in a browser; no separate audio software is required.

The Free plan costs nothing and gives 100 bonus credits during a 7-day trial. Those credits lapse after the trial, which has no API access or commercial rights. Pro Monthly is 37.50 BRL a month, and Pro Yearly is 299 BRL a year; both list 300 credits per month and commercial rights. API billing is pay per call in USD, with a free tier and a separate account from Pro. Pixazo describes RESTful APIs for app and workflow integration. The tool is intended for video editors, game developers, motion and UI designers, podcasters, and app makers. It does not make full songs or offer multi-track mixing, and specific or branded sounds may need prompt refinements. Commercial use depends on plan terms.

Sonilo generates music and sound effects intended to follow a video's pacing, mood and scene changes. Users can upload MP4 or MOV video, or describe the desired audio in text. Sonilo processes the visuals while leaving the original audio available to keep, adjust, replace or layer. It generates several variations by default and accepts an optional prompt to guide style. The service also supports speech translation, video re-voicing, lip-sync re-rendering and SRT or VTT subtitles. Its API covers music and sound-effects generation, audio ducking, task polling and account usage; plugins are listed for Adobe Premiere Pro, Unity, Godot, Epic Games Fab, Roblox Studio and Defold. Free provides 2,000 credits every two weeks, with preview-quality exports and videos up to 3 minutes. Pro is $11.99 a month, billed yearly as $143.88, and Premium is $23.99 a month, billed yearly as $287.88. Commercial use is limited to specified paid plans and eligible API users. Sonilo says uploaded videos, prompts, outputs and related data may be used for training and product improvement by default.
