With A Sound Effect, Asbjoern has created a web site where our international community can browse, learn, and share the vast fruits of our labors. Together we are accelerating the very real potential power of sound design as a recognized art form.
A Sound Effect is an excellent resource for us to keep our animated films sounding unique and exciting.
A Sound Effect is a great asset to have discovered.

We’ll definitely be back!
There are many great independent sound effect libraries available these days. The main problem with having so many, is keeping track of them!
A Sound Effect is a great hub, and is one of the first places I visit to look for sounds by category or genre. I started coming here to see if I could find libraries that I knew I had heard, but forgot WHERE I had heard them.
And in the process discovered libraries I never would have found otherwise. Great work! Keep it up!
We're always looking for new sounds to mangle, so when A Sound Effect had a holiday sale, I tried them out.
The purchase experience is really smooth and quick, and delivery is almost instant.
I'll definitely come back to them again in the future!
A Sound Effect is a wonderful resource for indie sound effects libraries. On top of that, it has some of the finest sound design, film and game audio interviews!
I often need very specific types of sounds so I've become a big supporter of independent recorders.
Until now I've always had to go to their individual websites. Now I can find them all in one place.
And, Asbjoern is great to work with!
A Sound Effect is a well curated boutique sound effects shop and a great place to find industry interviews and learning resources.
