#X text 226 4 FIDDLE - pitch estimator and sinusoidal peak finder;
|
|
#X text 8 70 The Fiddle object estimates the pitch and amplitude of
|
|
an incoming sound \, both continuously and as a stream of discrete
|
|
"note" events. Fiddle optionally outputs a list of detected sinusoidal
|
|
peaks used to make the pitch determination. Fiddle is described theoretically
|
|
in the 1998 ICMC proceedings \, reprinted on http://man104nfs.ucsd.edu/~mpuckett.
|
|
;
|
|
#X text 8 170 Fiddle's creation arguments specify an analysis window
|
|
size \, the maximum polyphony (i.e. \, the number of simultaneous "pitches"
|
|
to try to find) \, the number of peaks in the spectrum to consider
|
|
\, and the number of peaks \, if any \, to output "raw." The outlets
|
|
give discrete pitch (a number) \, detected attacks in the amplitude
|
|
envelope (a bang) \, one or more voices of continuous pitch and amplitude
|
|
\, overall amplitude \, and optionally a sequence of messages with
|
|
the peaks.;
|
|
#X text 8 296 The analysis hop size is half the window size so in the
|
|
example shown here \, one analysis is done every 512 samples (11.6
|
|
msec at 44K1) \, and the analysis uses the most recent 1024 samples
|
|
(23.2 msec at 44K1). The minimum frequency that Fiddle will report
|
|
is 2-1/2 cycles per analysis windows \, or about 108 Hz. (just below
|
|
MIDI 45.);

is below the low threshold \, no pitches or peaks are output. The high
|

|
#X text 560 152 A period in milliseconds (50) over which the raw pitch
|
|
may not deviate more than an interval in half-tones (0.5) from the

|
average pitch to report it as a note to the "cooked" pitch outlet.
|
|
;
|
|
#X text 560 213 A period in milliseconds (100) over which a re-attack
|
|
is reported if the amplitude rises more than (1) dB. The re-attack
|
|
will result in a "bang" in the attack outlet and may give rise to repeated
|
|
notes in the cooked pitch output.;
