FFT with Accelerometer Data

I am trying to find an open source FFT solution that is written in low level C. I need to run a triple axis accelerometer coordinates through the FFT to due vibration analysis. I have looked all around through google and cannot find anything. Space is a major concern for me in because this is going on a small device. Is there any good solutions that are open source? Thanks in Advance.

Solution

  • You can try out my FFT implementation libsimplefft.

    It provides a low level C API for FFT and Fast Convolutions, as well as a Java JNI Wrapper.

    Its build using GNU Autobuild and an Android NDK Build target (both included).

    Look here for example!
