SFX Engine
SFX Engine generates custom sound effects from text prompts, built for audio producers, video editors, and game developers who need unique audio without digging through stock libraries. Type a description like "thunderstorm with rolling thunder and heavy rain" and the AI produces a studio-quality sound effect you can download and use commercially.
Unlike fixed sound libraries where you settle for close enough, SFX Engine creates infinite variations from detailed text descriptions. You buy credits and pay only for what you generate, with no subscription required. Every sound effect includes commercial licensing by default with no royalties. Paid plans add background music creation, API access, and priority support.
Wildlife Studios, RingCentral, and the Art Institute of Chicago are listed as customers. Starter costs $8 per month (billed yearly at $96) with 6,000 credits, Creator is $20 per month with 48,000 credits, and Pro is $72 per month with 180,000 credits. Sign up requires no credit card.
