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.

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.
