Pink Noise Program
Want software, preferably written in PHP, but other platforms are OK (Matlab or C) that will produce a wav file lasting at least 10 sec containing band-limited white noise, centered around a particular audio frequency, with a given band pass. I want this to work between 20 Hz and 20 KHz.
For example, suppose that the chosen frequency is 12,315, and the size of the band is 100 hz. This program should produce “pink” noise between 12215 and 12415 hz.
Would prefer a program that could filter an arbitrary wav file.
