[IDEA] equalise volume output from different 'sources'

[Mattt]

Using a calibrated spl meter, there is typically 5dB difference between the radio and and a modern (loudness wars) album. Older albums there can be a 10dB difference. +10dB is perceived as twice as loud.

here's a couple of radio streams I use.
