Original session tape
May be multitrack, two-track or mono. It is not necessarily a finished album and may need mixing.
THE ENCYCLOPEDIA / 06
Master tapes & editions
Know the source. Understand the copy.
Stereo master
The approved two-channel mix or mastered programme. It may be analogue or digital, depending on the production.
Commercial tape copy
A saleable duplicate made through a specified chain. It is not the unique original master merely because its box says “master tape”.
