Abstraction and externals documentation

Abstractions

Audio

audio-stim
Generate audio stimulus properties.
bandpass~
Band-pass filter with a bypass option.
bandpass24~
24 channels band-pass filter with a bypass option. (Requires bandpass~).
fadeio~
Fade in/out manager.
gaussian-gain
Compute the gain to apply to a speaker depending of the source size.
gaussian-spat24
Compute the gains to apply to a 24 channels sound system according to the position of the speakers and the source width. (Requires gaussian-gain).
master24~
24 channels master with a fade in/out manager. (Requires fadeio).
motion24~
Spatialize an incoherent stimulus (noise for example) over 24 channels. (Requires gaussian-spat24).
mute24~
24 audio channels mute.
noise24~
24 audio channels of white noise. Each channel generate independent noise (useful to simulate source motion).
partconv-im~
1 channel filtering object using partitionned convolution method. This object can be bypass. (Requires partconv~).
playfile~
Play any wave file in argument using a table method.
spectral-corr24~
24 audio channels applying spectral filtering on input signals. This object can be bypass if necessary. (Requires partconv-im~).
stimulus-position
Generate the azimuth position stream according to several parameters.
vumeter~
GUI object displaying the level in dBfs (full scale) of an audio signal.

Head tracking (Flock of Bird)

bird-conv-ang
Conversion of an angular Flock of Bird raw data flow in azimuth, elevation and roll in degrees.
bird-conv-pos
Conversion of a position Flock of Bird raw data flow in x, y and z in inches or centimeters.
bird-ctl
Flock of Bird acquisition control features.
bird-raw-pos-ang
Flock of Bird raw flow extraction. Output two separate raw flows, one for position, one for angles.

Miscellaneous

cmp-gate
Comparative gate using 2 boundaries.
get-button
Send a unique bang when the right key is hit.
get-displacement
Get the displacement according to the duration and speed of an object.
in2cm
Convert inches in centimeters.
percentage
Compute a given percentage of a value.
pr-bit
Generate a pseudo random bit (0 or 1) and then alternate the value.
rand
A superior layer of random object. You just to specify a range of value from 0 and shift of this range.
serial-ctl
Superior layer to comport in order to open/close, specify a baud rate for the serial port.

Externals

staircase
Staircase method.
