FFT package :
ÿÿÿÿÿÿÿÿÿÿÿÿÿ
Purpose:
ÖÖÖÖÖÖÖÖ
These programs perform a frequency analysis using the fast Fourier
transform. They expect an Armadeus formatted input file and output graphs in
Draw format.
FFT_2D outputs a two dimensional graph with level as y-axis and
frequency as x-axis.
FFT_3D option 3D outputs a three dimensional graph with frequency
along the y-axis, time along the x-axis and level is deflection.
FFT_3D option sonograph outputs a three dimensional graph with
frequency along the y-axis, time along the x-axis and level is black level.
C sources are included.
Requirements:
ÖÖÖÖÖÖÖÖÖÖÖÖ
RISC OS3, ARM3 (the program uses the SWP op-code which is not
supported by ARM2, ARM3 does and I don't know for the others).
