very sad news. i always appreciated his music and his ethics as a composer.
mi teacher, the late héctor tosar, also appreciated him very much. a real
no-nonsense composer, in my opinion.

i'm glad i got to see him attending a concert with one of his pieces in
NYC in january 2010, 101 years old at the time.

well, we all die sometime. but it's a real achievement to make it beyond 
100 years ... not many do.

i remember being very impressed with a movement for wind quintet that is 
just a single pitch [maybe also all within the same octave] that is 
passed through the ensemble.

carter- the extreme musical intellectual [like babbit or boulez], just 
writing a single pitch!

Dear List! 

I am mostly using csound from an engineering perspective rather than from a musical one. I realize this is not the "intended" use, so it may be a bit much to hope for engineering tools within csound, but I always felt that particularly algorithmic composing is a exciting bridge between these disciplines and since csound lends itself so well to that area, maybe there is hope for my engineering (dark?) side. 

What I in this particular case was hoping to achieve is a standard 1/3 octave band filter bank - kind of like a multi band eq. Ideally both for analysis -  i.e. evaluating levels of each 1/3 octave band when running something through them - and sound modification, i.e. applying (negative) gain to each band to shape the outgoing spectrum. 

Could this be achieved using existing opcodes such as resony or similar?

Best regards,
/Anders

Sure. Apart from reson there are other bandpass filters you could try
out. Just set them up in parallel across the frequency range and enjoy
the show!

Rory.

Out of the various bandpass filters, butbp is more likely to give a
clean output. Resonant filters in my understanding are designed more
for filtering as an effect than for utilitarian signal processing
(they introduce significant phase distortion and have lumpy
passbands).

Try also eqfil, which is a good equaliser filter.

Here's a 1/3-octave graphic equaliser with user-defined number of bands.
It uses a function table to define the gains for each band. 

opcode Eq, a, aiipp
as1,ifreq,itab,ibnd,icnt xin
inxtf = ifreq*2^(1/3)
if (icnt >= ibnd) goto bank
if (inxtf > sr/2) goto bank
as1 Eq as1,inxtf,itab,ibnd,icnt+1
bank:
kgain table ibnd-icnt, itab
ibw = ifreq/1.5
as1 eqfil as1, ifreq, ibw, kgain
xout as1
endop


instr 1
ilowest = 100
imaxbands = 24
itab ftgen 0,0,32,-7,1,10,0.5,10,1,4,1
a1 diskin2 "jarrettm.wav",1
a2 Eq a1,ilowest,itab,imaxbands
outs a2,a2
endin

Ooh, fantastic! Thank you very kindly!
Will try it out tomorrow...
