#X text 8 56 The Bonk object takes an audio signal input and looks
for "attacks" defined as sharp changes in the spectral envelope of
the incoming sound. Optionally \, and less reliably \, you can have
Bonk check the attack against a collection of stored templates to try
to guess which of two or more instruments was hit. Bonk is described
theoretically in the 1998 ICMC proceedings \, reprinted on http://man104nfs.ucsd.edu/~mpuckett.

#X text 8 377 In this patch \, after starting DSP \, you can print
out the raw or cooked output using the two "spigots" or listen to a
synthesizer output by raising its volume.;

#X text 8 309 Bonk's analysis is carried out on a 256-point window
(6 msec at 44.1 kHz) and by default the analysis period is 128 samples.
The analysis period can be specified as Bonk's creation argument but
must be a multiple of 64;
#X text 532 185 Minimum time (msec) between attacks;
#X text 532 140 Describes how energy in each frequency band masks later
energy in the band. Here the masking is total for 4 analysis periods
and then drops by 0.7 each period.;
#X text 530 214 Forget all templates and start learning new ones. The
argument gives the number of times you will hit each instrument (10
recommended.) Turn on the output volume above for audible feedback
as you train Bonk. "Learn 0" exits learn mode.;
#X text 530 298 Forget the last template. In Learn mode \, use "forget"
to erase and record over a template.;

#X text 218 12 BONK~ - an attack detector for small percussion instruments
;
#X text 8 174 Bonk's two outputs are the raw spectrum of the attack
(provided as a list of 11 numbers giving the signal "loudness" in the
11 frequency bands used) \, and the "cooked" output which gives only
an instrument number (counting up from zero) and a "velocity". This
"velocity" is the sum of the square roots of the amplitudes of the
bands \, normalized so that 100 is an attack of amplitude of about
1 The instrument number is significant only if Bonk has a "template
set" in memory.;
#X text 532 52 Set low and high thresholds. Signal growth must exceed
the high one and then fall to the low one to make an attack. The unit
is the sum of the proportional growth in the 11 filter bands. Proportional
growth is essentially the logarithmic time derivative.;
