Hi Csounders,

Excuse me I don't understand:

It's true that the manual suggest that octdown converts a-signal to
d-signal:
 dsig octdown xsig, iocts, isamps[, idisprd]
 wsig noctdft dsig, iprd, ifrqs, iq[, ihann, idbout, idsines]

 >s>   - noctdft converts d signals to w signals
>No longer exists

 >s>   - spectral opcodes use the w signals

 But how to get a w-signal? Nothing is mentioned anywhere.

What do you mean by w-data is produced by spectrum?
I know what is a spectrum, I understand what is w-data but how to
operate that in CSound?
I can't find anything in any manual.

Regard.
