'''Compression and Limiting''': Audio compression is not the same as audio data compression, as in this is not a discussion on how to make audio data files take up less disk space. Audio compressors use the peaks or the immediate RMS levels to help prevent sound from exceeding a certain threshold. The audio limiter does the job of stopping all sound at a given level, usually at 0 dBFS or some predefined limit. '''Normalization''': In contrast to compression, the normalization process doesn't actually manipulate audio dynamics within a piece, but rather elevates the more silent parts nearer to the louder ones. The default of most music mixing, recording or mastering applications would be 0 dBFS. The concept of Normalization can also be split into Loudness Normalization and Peak Normalization. We are more concerned with Loudness Normalization since we are not involved in the production process, only the enjoyment of a piece.
