interesting thats what i suspected. so just normalize the volume to a certain standard ?Transfer engineers mostly just transferred songs from the recording medium (hard wax disc) to a wax master which was used to produce (probably in several steps) a metal pressing master. Or something like that. I suspect they could adjust the volume and the start/stop points and not much else.
oh wow ok thats pretty cool.. maybe i should been more clear haha more so 1950s 60s 70s ?Tape didn't exist. The performance was captured through a giant horn (later a single mic) and straight to a hard wax disc temporarily kept soft by the heat of an incandescent lamp. It was what it was, no gluing from tape saturation.
They practiced their singing, instruments and songwriting !how did people originally master music ?
