What is AnnaLies?

AnnaLies is a program for the spectral analysis of Sound Designer II files. The analysis procedure used is that of the Short Time Fourier Transform (STFT), implemented as using a radix two Fast Fourier Transform algorithm. The program takes a sampled time domain signal and and converts it to a discrete frequency domain representation. The original version of this program, AnnaLies1.0, was written jointly by David Hirst and Thomas Stainsby in 1991, and was based on research carried out as part of David's Master's thesis [Hirst 1985].
 
Operation of the AnnaLies program follows in the intuitive manner to which Macintosh users have become accustomed. The overall analysis procedure essentially takes a Sound Designer II stereo sound file, performs an STFT analysis of it and stores the result in an FFT (Fast Fourier Transform) file, which can then be called up and have its data displayed in either a 2D or 3D format.
