13 - Capture and storage technique How the sound was originally captured and stored. Re-releases of recordings should
be coded for the original capture and storage technique, even though such
re-releases may have been enhanced using another technique.
a - Acoustical capture, direct storageUsually a disc or cylinder recording, captured using an acoustical horn and
diaphragm and stored directly on a master surface. Most acoustical recordings
date from before 1927/29 when electrical recording equipment became
available.
b - Direct storage, not acousticalDisc recordings captured using electrical equipment and stored directly on a
master surface. All recordings made with microphones and other electrical
equipment prior to the availability of magnetic recording techniques in the
late 1940s used direct storage.
d - Digital storageSound recordings which were captured electrically and stored using digital
techniques.
e - Analog electrical storageSound recordings which were captured using electrical techniques and stored as
modulations and pulses on a magnetic surface. Most recordings made from the
late 1940s until early 1980s are analog electrical recordings.
