5.0 OPTICAL COMPRESSION-WHAT IS IT?
There are many ways to create a circuit that controls the gain
reduction of a compressor. Each method has its own characteris-
tics and all have produced popular compressors over the years.
One of the most popular types is the optical compressor.
An optical compressor is created from the combination of a light
sensitive resistor called a photocell, and a light source such as a
small bulb or LED. Devices called optocouplers combine a photo-
cell and light source inside a light-proof package. The photocell
increases its resistance when input level increases the intensity
of the light - that increased resistance provides the compression.
While attack is the time it takes for compression to occur, “release”
is the time it takes for the signal to return to normal. Photocells
have a characteristic called “memory” that makes such a compres-
sor interactive. When just a few brief attacks have been
experienced, the photocell recovers quite fast, bringing back the
level more quickly. However, after repeated and constant attack-
ing, the photocell builds up a memory of the light pulses and
recovers more gradually. This helps to smooth out the compres-
sion and preserve the character of the sound.
