Well, I ain't released at all, I just a briefly mentioned. But in a portuguese mail list they were so excited about it I had to release and did thank and make references to all of who helped, especially Mathieu, of Course, without whom I'd still be stuck and not kowing what do to at all :) And as

Oops, couldn't find or load the [mtx_phon_curve]. But I got Pd Extended with iemmatrix, what could I be doing wrong? do you all have it? cheers alex 2010/3/24 Alexandre Porres por...@gmail.com Hi, I found an acient thread that really interests me a lot! In Fact, I just compiled 2 ways of

Hello all, This abstraction is very nice, but computing matrices on every note is quite expensive on the CPU, no? Perhaps it would be better to store it in a table, let say using 60 (pd)db as a reference. The only thing is that low and high notes are multiplied by factor much bigger than 1 and it

Hi Alexandre, hi all, Yesterday I corrected an error in mtx_phon_curve-help.pd and changed the behaviour of [mtx_phon_curve] abstraction (pure-data.cvs.sf.net/cvsroot/puredata/externals/iem/iemmatrix/abs). Now the output is in dB, just like everyone would expect; before it was p^2/p0^2 ...

Hi Alex, all ...but PDs dB goes to 0, because we have to have the numbers following the same scheme - so that 0 means 0 always I think. Industry uses dBFS (deciBel Full Scale) because it is measuring the signal against the full scale from -96dB in 16bit recordings to 0dB (all bits used).

Hello all, Very nice, mr. Zmoelnig. Of course, this is exactly what I need. It appears that the object [list length] cannot be created. Is this a pd 0.40 new feature of the [list] object ? (using pd 0.39-2 extended on Linux) To use this very nice abstraction, I simply need to multiply the
