Fourier
2D FFT/iFFT plugin 1.0
User-friendly 2D FFT/iFFT (Fast Fourier Transform) plug-in for Adobe PhotoShop compatible plug-in hosts. It uses one of the fastest implementations of the Discrete Fourier Transform and has many applications including periodic noise removal and pattern detection. This can be very useful in analyzing fingerprints, paper sieve patterns etc.

Note Detector 1.0.2.9
Note Detector can be used as a guitar tuner or a singing voice pitch trainer. I use it as an educational device. I have a bamboo flute laying aroung the house and I always wondered what notes came out when I blew on it. I'm not musically inclined enough to determine that kind of stuff with my ear. With Note Detector I was able to map out where all the notes on the flute were and how hard to blow in order to get an A instead of an A#.

Frequency Analyzer 2.0
Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer technically speaking performs a Fast Fourier Transform of the sound. What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the noise of sibilants. The size of the program is only 64k! (zipped 32k)
