the last outlet of miller puckettes fiddle~ outputs sinusoidal peaks and amplitudes... i was wondering if there was any object that did the same thing but at sample rate? i need those numbers to be fast!

also, fiddle~ only seems to think 6 - 8 peaks are important enaugh to output... after that the output is near to zero in amplitude. is there a way to make fiddle~ more sensitive to less dominating peaks?

try sigmund~ - mr puckette's own successor to fiddle~ - if memory serves me yada yada, you can choose to output more peaks...

I second trying [sigmund~] (it gives more accurate results than [fiddle~].

Also, you can't get peaks more than once per hop size - say your hopsize is 512 samples, and your sample rate is 44.1kHz - then the speed of the results is about once every 11ms, for which max messages are fine.

Finally, when you say fiddle~ thinks 6-8 peaks are enough, and that the others have a low amplitude it sounds like you're not identifying an actual problem with fiddle - it can only output the amplitudes as they are in the input signal. The amplitude's are measured values, and it's best for them to be accurate - many sounds will not have that many strong peaks, and also, you should expect many peaks to "near to zero" in amplitude - as amplitude is a linear measurement, whereas your perception is logarithmic. If you use [atodb] on the amplitudes you may get more manageable values to use - depends on what you want them for though

what i want to do is make something that resynthesizes an input signal with an x amount of sinewaves. i want to be able to go from 1 oscillator to maybe 256...

Have you looked at oscillators~ from CNMAT? That and SDIF formatted analysis files may help.

The [sigmund~] help patch has an example. You want to use the track functionality of [sigmund~] which tries to track partials between frames, as well as identifying peaks.....

The CNMAT stuff is also worth checking out

Look at the iana~ and transcribe~ objects also.
