I expect removal of very high and low frequencies could make some music sound subjectively better.

- fuzzfactor 5y agoSometimes it may be helpful to look at some fundamentals from a completely analog point of view before trying to make the most out of what digital has to offer. If so Chapter 14 Fidelity and Distortion in Radiotron (RDH4) can be a good place to start: https://ia801602.us.archive.org/18/items/bitsavers_rcaRadiotr1954_94958503/Radiotron_Designers_Handbook_1954.pdf https://ia801602.us.archive.org/18/items/bitsavers_rcaRadiot... >The values of total harmonic distortion to provide objectionable distortion are 2 % with a frequency range of 15000 c/s and 10.8% with a frequency range of 3750 c/s for music, and 3% and 12.8% respectively for speech, with a pentode. Even if almost nobody is using pentodes any more, you could do worse. The whole thing is 1400 pages, you can see what engineers were up to with their slide rules back then. Chapter 19 if you really want to know about decibels . . .
