HRA for the Masses

Ask virtually any music listener if they own any high-resolution audio files, and they’ll likely give you a blank stare, wait a beat, and then maybe come back with a question like, “You mean like CDs I put on my computer or something?”

For the record, high-resolution refers to music recorded at better than CD’s 44.1-kHz/16-bit quality, usually 96-kHz/24-bit, typically written as “96/24.” (See my high-rez audio audio primer here).
