However, there is also noise in the equipment used to make audio recordings, and that noise, being incorporated in the recordings, will be boosted along with the desired audio. In my experience, normalization does not make sense except to match, albeit imperfectly, the audio levels in successive program elements. My downstream audio processing is set to produce a consistent sound (and loudness) for the program stream. Without the normalization, with audio files whose levels are all over the map, the task of the downstream audio processor(s) is much harder. Therefore, everything that goes into /var/and gets normalized.
