Compressing Sound

compression limiter
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.

syfx compander
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.
