AI SFX Lab vs Pixazo AI SFX Generator

AI SFX Lab is a web tool for generating custom sound effects from text prompts. Users can set duration, ask for variations, choose loop behavior and style, and specify sounds the AI should avoid. A prompt enhancer can refine a description before generation. The maker says results may differ between generations and recommends previewing clips, changing settings, and trying again. The free plan costs nothing and provides 100 credits each month, with generations up to five seconds; it has no downloads or commercial use. Starter costs $4.90 a year, billed annually at $59/year, and includes 600 monthly credits. Creator costs $9.90 a year, billed annually at $119/year, with 2,000 credits and up to three simultaneous generations. Pro costs $24.90 a year, billed annually at $299/year, with 7,000 credits and up to five simultaneous generations. These paid plans support clips up to 22 seconds and downloads in WAV, MP3, and FLAC. Monthly credits do not roll over. Commercial use is restricted to paid plans and governed by the maker’s terms and policies, which prohibit deceptive audio, rights infringement, and misleading emergency sounds. The product is aimed at creators, game developers, editors, podcasters, streamers, marketers, Foley artists, and creative teams.

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.
