AI Sound Effects Generator: free FAQ
Is the AI Sound Effects Generator really free?+
Yes, to start. A free account (no card) gets 20 credits once your email is verified, and a sound effect starts at 1 credit, so the free credits cover a first run. After that, credit packs start at $1.99 with no subscription.
How many sound effects do the sign-up credits cover?+
Up to 20, at 1 credit each, from the 20 credits a verified free account starts with. A long ambient bed costs the same as a short hit.
How do I write a prompt that works?+
Name one sound, what makes it and where it happens, such as rain on a car roof heard from inside. Several sounds in one prompt tend to blur together.
Can I put the effect under a video?+
Yes. Download the file and place it in any editor that accepts an MP3, or send it to the Video Editor and lay it under a clip there.
Do I need a subscription?+
No. You can pay as you go: credit packs are one-time purchases and their credits never expire. If you would rather have a steady supply, the monthly Starter ($7.99), Creator ($19) and Pro ($49) plans refill your credits each month, and you can cancel anytime. Unused monthly credits do not roll over.
