SFX Engine

SFX Engine is an AI sound effect generator. A user describes a sound in text, such as a car door shutting in a parking garage or thunder rolling over a dark sea, and the service generates it in a few seconds. Each request can produce up to four takes side by side, so the user can keep the one that fits. Length, material, distance and mood can be specified in the prompt. The output is licensed for commercial use and described as royalty free, for use in film and video edits, games, podcasts, apps, ads, social media and songs. Typical uses include foley, ambience, UI clicks, coin pickups, spell effects, podcast intros and transitions, and starting layers for sound design in a DAW. The site also offers a searchable library of sounds to browse and download, plus background music creation on all plans and API access. Plans are credit based, and a sound effect costs 3 credits. Starter is $10 a month for 500 credits, which the vendor says is about 166 sounds a month. Creator is $25 a month for 4,000 credits, and Pro is $90 a month for 15,000 credits with priority feature requests. The site advertises a 50 percent discount on the first month of monthly plans and a yearly option that saves 20 percent. Every plan includes commercial use, studio quality output and support by email.
