Program Descriptions
Programs 1-8 are sinewave high accuracy oscillators
with frequency and level settings that match program
names.
9 Pink Noise
LVL
-12dB
Program Description
The Pink Noise program produces filtered noise with
equal energy per octave. The only parameter
provided is the level control, which attenuates from
dBFS and displays attenuation in dB. The program
loads with a value of -12dB from dBFS.
About the Binaural Simulator Program
The Binaural Simulator is designed to alter stereo
recordings for binaural presentation using headphone
monitoring. It includes the ability to add controlled
amounts of early reflections and reverberation, as well
as the ability to independently alter the binaural width
and level of direct sound, reflections, and reverberation.
Although it can be used in all machine configurations,
this program is intended for use in a cascade configuration
with it loaded into Machine B and a reverb or
ambinence program loaded into Machine A.
The synthesis is based on a simple model of the human
head. Information normally fed to one channel is delayed,
low pass filtered, and cross-fed to the opposite
channel. By adjusting delay time and frequency of low
pass filters, apparent binaural width is realistically
varied.
The Binaural Simulator has three independent synthesis
circuits: one of direct sound, one for early reflections,
and one for reverberation. Reverberation generated
in Machine A is fed directly to the rteverberation
simulator. Direct sound feeding 480L inputs is fed to
the direct sound simulator. The program includes six
independent echo delays, each with variable time and
level control parameters. Their outputs are fed to the
early reflections simulator. A precision mixer provides
level adjustment for each simulator.
