<p>BIRD LIKE OBJECT is a monthly published series of 5 experimental
audio works based on the sound exploration of the « boids algorithm ».
The five piecess are produced and composed for four audio channel
system but also have been mixed in binaural stereo version.</p>
<p>For the generation of the sound material i coded a custom software
using Pure Data environment. I build a “instrument” linked a 2d boids
visual implementation with a basic AM four channel audio synthesizer.</p>
<p>Flocking boids is a computer model for the coordinated motion of
groups (or flocks) of entities called boids.Flocking represents group
movementas seen in bird flocks and fish schoolsas combinations of
steering behaviors for individual boids, based on the position and
velocities of nearby flockmates. Though individual flocking behaviors
(sometimes called rules) are quite simple, they combine to give boids
and flocks interesting overall behaviors, which would be complicated to
program explicitly.</p>
<p>Flocking is often grouped with Artificial Life algorithms because of
its use of emergence: complex global behaviors arise from the
interaction of simple local rules. A crucial part of this complexity is
its unpredictability over time; a boid flying in a particular direction
may do something different a few moments later. Flocking was first
proposed by Craig Reynolds in his paper « Flocks, Herd, and Schools: A
Distributed Behavioral<br>
Model, » published in Computer Graphics, 21(4), SIGGRAPH’87, pp. 25-34.</p>
<p>The basic flocking model consists of three simple steering behaviors (or rules):</p>
<p>Separation<br>
Steer to avoid crowding local flockmates.</p>
<p>Alignment<br>
Steer toward the average heading of local flockmates.</p>
<p>Cohesion<br>
Steer to move toward the average position of local flockmates.</p>
<p>The instrument use two groups of four “birds”. They are in a 2D space.</p>
<p>Group 1 (A1(x,y), B1(x,y), C1(x,y),D1(x,y))<br>
Group 2 (A2(x,y), B2(x,y), C2(x,y),D2(x,y))</p>
<p>Amplidtud modulation with sawtooth oscilators. There are 8 am
modules, i connect the value of A1(X) with the freq of the carrier
oscilator and A2(Y) is conect to the freq of the modulation oscilator in
the am module 1, the same with the others..</p>
<p>AM mod 2 ( carrier = B1(X), modulation = B2(Y) )<br>
AM mod 3 ( carrier = C1(X), modulation = C2(Y) )<br>
AM mod 4 ( carrier = D1(X), modulation = D2(Y) )<br>
AM mod 5 ( carrier = A2(X), modulation = A1(Y) )<br>
AM mod 6 ( carrier = B2(X), modulation = B1(Y) )<br>
AM mod 7 ( carrier = C2(X), modulation = C1(Y) )<br>
AM mod 8 ( carrier = D2(X), modulation = D1(Y) )</p>
<p>finaylly the 8 modules are remixer to 4 outputs, 2 per each channel.
Channel 1 ( mod 1 & mod 5 ), channel 2 (mod 2 & mod 6), channel 3
(mod 3 & mod 7) and channel 4 (mod 4 & mod 8)</p>
