hi,
does anybody know, how the list of 25 numbers at the bark output of the object correspond to the frequencies and their levels?
here’s the number it spits out in the helpfile:

print: -79.315529 -60.032146 -53.785034 -56.146988 -63.547085 -69.282944 -70.173416 -67.672081 -66.449852 -63.952312 -64.138092 -63.238163 -64.236931 -66.699699 -70.048134 -72.092392 -70.270226 -74.324364 -73.098953 -76.922546 -51.995209 -78.961807 -69.088272 -55.860600 -96.982849

From my first link:

"The Bark scale ranges from 1 to 24 Barks, corresponding to the first 24 critical bands of hearing [39]. The published Bark band edges are given in Hertz as [0, 100, 200, 300, 400, 510, 630, 770, 920, 1080, 1270, 1480, 1720, 2000, 2320, 2700, 3150, 3700, 4400, 5300, 6400, 7700, 9500, 12000, 15500]. The published band centers in Hertz are [50, 150, 250, 350, 450, 570, 700, 840, 1000, 1170, 1370, 1600, 1850, 2150, 2500, 2900, 3400, 4000, 4800, 5800, 7000, 8500, 10500, 13500]."
