- 3 interchangeable window functions to reduce spectral leakage (Blackman-Harris (default) , Hanning or rectangular).
- Intelligent adaptive fft size allocation system
- Logarithmic scales (X and Y)
- The ability to create a second reference plot,
- Precise peak frequency value display in Hz
- A unique amplitude relative gradient colour scheme

Please rate Free FFT HD and leave feedback of any suggestions or compliments or email me in regard to any compatibility issues you experience to ben.adrian.jones@gmail.com and i will try to resolve them as soon as i can. (this is my first attempt at creating an android application so apologies in advance if you experience any abnormal behaviour)
Free FFT HD has been tested on tablets and is optimised for the Nexus 7.

    As soon as it starts it announces that it has to close. Looks promising however. Look forward to the fix.
