Hi, I did, in fact I'm using sigmund~ cause somewhere in this list, someone (Miller?) said it was better to use it instead of fiddle~. Can anybody confirm that sigmund~ is better?

Re: [PD] frequency components analysis
You could try the ATS technique by Juan Pampin. You will find it at the SourceForge CVS. It has several applications associated like an object for pd(atsread), several UGs for Csound, a GUI for Analyzing/Editing(ATSH) and a non-gui stand alone program for analysis(Atsa). It runs under Linux, Windows and OS10.

Re: [PD] frequency components analysis
Hi Isidro, Thank you for the link, the problem is that I want to extract the frequency components of a sound in realtime, like from a mic connected to my computer, and AFAIK the ATS object works only with files. Do you have any other ideas? Does anybody else? Thank you! ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
