AI SFX Lab vs Sonilo

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.

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.
