Subject: RE: Why music sounds worse.
Compression of volume range was a trick used to improve signal to noise ratio by bringing low levels higher at the transmit end, then reducing them back down to their proper level at the receive end through an expander, which reduced any inherent noise as well. It worked well in the days of analog broadcasting. These were called compander circuits.
