Hi Fons,
I had a copy of the spec at one time, but I cant find it, I do still have
the formular for calculating the band centres though:
freq = 25 x 10^(band/10)
with band in [0,29]
I can probably find it again when I get back to work next week.

Hello,
I'm looking for the 'official' (ANSI/IEC/ITU/???) specs for the set of
1/3 octave bandpass filters used for sound analysis. ISTR there are
different grades, depending on precision and filter order. If someone
would have them (or a pointer) please drop me line.
TIA,
