Kiss FFT Reviews

Small efficient and open source, the best FFT libiary I've ever seen

The best........ EVER!!!!!!!!!, and all other libraries suck compared to this one

A great library - very simple to use, with the most convenient license and very good performance. The only additional thing I'd wish is more detailed documentation.

Exactly as advertised- small, simple to use, supports floating- and fixed-point versions, and even comes with notes on what you can easily mess with to reduce the code size.

great, efficient lib. Thanks ! Note: Including a very simple "gettingstarted.c" could be a plus, to help users to understand in 1 minute how to do a basic floating point fft. Regards

I use Kiss FFT for real-time audio spectrum analysis, and it's excellent. It's easy to understand and integrate, it supports both floats and doubles, it compiles clean in .NET 2008 (32-bit and 64-bit), it's plenty fast enough for most needs, and it's incredibly small.

I used it on a Beaglebone and it works really well.

Just what I was looking for. A KISS FFT for a simple feature in a game. This will make my task easier to add some simple frequency based visuals to a game engine. I am planning on releasing my code MIT so this being BSD licensed helps make that possible! The game engine is Torque3D which is MIT as well. Thanks for making this!

Excellent implementation of FFT / IFFT! Love it!

very nice projects, thanks for posting it!

very easy to set up, straightforward usage, and it just works

A great library that does as it says. Simple, fast, easy to use, and works 100%. Thanks :o)
