Compressing
Sound
The standard method for fitting a wide dynamic range
source into a smaller dynamic range is compression
limiting. Many manufacturers limit their maximum sound
output by severely compressing the output level above a
threshold. This results in flattening the sound above a
given threshold, causing sounds to become flat and
unrealistic.
Below the threshold, the sound is linear and soft sounds
are still soft; you still can't hear the quiet parts.
Another problem with compression limiters is that in order
to avoid distortion at lower frequencies, slow attack &
releases are used that can result in clipping or under
amplification of the signal.
While Syfx technology can implement compression
limiters, the superior method is to smoothly and evenly
compress the larger dynamic range into a smaller range,
without amplifying the noise floor. In this manner, Syfx
provides an audio signal that maintains the feel of the
original signal with no noticeable audio artifacts, that
preserves the excitement and intensity of audio portions
that often represent the climax or turning points of a
program without adding any distortion.
