The De-Emphasis filter is pre-configured, with set parameters, and is used to attenuate the high-frequency components boosted during recording with pre-emphasis.
When the De-Emphasis block is used on audio recorded with pre-emphasis, its signal-to-noise ratio is greatly improved.
This block is ready to use, with no need (or ability) to add or grow algorithms.
