Dynamic Score

Making decisions on automated dynamic range compression requires a scoring system that takes three different measurements into consideration.

How audio encoders use psychoacoustic masking to reduce file sizes, and why this process creates audible artifacts in compressed formats.

Loudness and normalization

Understanding what is loudness, how it's measured and why standards exist.
