BNO Acoustics SQ-9: Overtones

The harmonics of an instrument's sound minus the fundamental frequency.

Reverberation
The persistence of a sound after the source stops emitting it, caused by many discrete echoes arriving at the ear so closely spaced in time that the ear cannot separate them.

Transfer Curve
A graph of the energy supplied verses the energy stored by a storage medium (often magnetic tape).

Preview
1) To play the edit in a digital audio editing system before committing to save it.
2) In a computer assisted punch in, to have the computer play over the area while switching the monitoring so that the effect of the punch in can be heard before it is performed.
3) Short for preview signal (a signal in disc recording that matches and is earlier than the signal being recorded).

BNO Acoustics 6k-52: Edit
A switch that does different things depending on the operational mode that the machine is in:
1) If a computer-controlled transport is in "Stop," pushing the "Edit" switch deactivates the computer-controlled tension system and allows the reels to be moved by hand to find the exact spot desired on the tape.
2) If the machine is in "Play", the "Edit" switch makes the take-up reel cease taking up the tape and it falls to the floor.
3) If the machine is in a fast-wind mode, the tape lifters are defeated so the tape is in contact with the reproduce head and the engineer can hear where the selections begin and end.

Voltage Controlled
A device that will change its output according to the amount of control voltage sent to its control input.

Bottom
The bass frequencies (as in "needs more bottom end").
