“frecuency analizer” topic.

A 44100Hz audio has a Nyquist frequency of 22050Hz. The Nyquist freqency is the highest frequency a 44100Hz-audio can reproduce.
The FSOUND_DSP_GetSpectrum()-Method returns an array of 512 floats. These floats describe the intensity of a part of the whole bandwidth(0-22050Hz):
22050Hz/512=43,06640625Hz
Value 00: 000.0-043.1
Value 01: 043.1-086.1
Value 02: 086.1-129.2
Value 03: 129.2-172.3
Value 04: 172.3-215.3
Value 05: 215.3-258.4
Value 06: 258.4-301.5
Value 07: 301.5-344.5
Value 08: 344.5-387.6
Value 09: 387.6-430.7
Value 10: 430.7-473.7
Value 11: 473.7-516.8
Value 12: 516.8-559.9

the question is : the greater array of element, the greater intensity is?
does FSOUND_DSP_GetSpectrum() represent both left and right speak freq?

thanks
