Re: Seeking frequency analysis software



There are many FFT (fast Fourier transform) applications for the Macintosh.
My favorite is "Sound Edit" by Farallon Computing, but it is an old
application I got when I bought a sound interface from them. There was a
new piece of FFT C code optimized for the Power Mac on the MIT Info-Mac
hyperarchive yesterday. See
http://hyperarchive.lcs.mit.edu/HyperArchive/Abstracts/Recent-Summary.html
The archive is searchable. Search on the term "fft" for code, and on "sound"
for applications. There are many of both. A new one called "SoundVision D50"
claims to do very fast (real time) FFTs on even modest Macs (128 point FFTs
on 68030 33MHz Macs, 256 point on faster machines), and the latest hot code
(ffts-for-risc-121-c) will do a 1024 point FFT in a quarter of a millisecond
on the most powerful Mac available.
