Hi list, I am using William Brent's [cepstrum~] to calculate cepstral coefficients from a section of an audio signal. My object outputs 512 the real-valued coefficients as pd message list, which I would like to convert to their absolute value. I can't seem to find an easy way to do this except for possibly sending the list to an array and using tabread to serialize, calculate the absolute value for every element and send it back to another array, then requesting it as a list again. Has anyone got a better idea?
thank you! P _______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
