BNO Acoustics SQ-9 Alternating Current

Electric current which flows back and forth in a circuit.

Axis
A line around which a device operates. Example: In a microphone, this would be an imaginary line coming out from the front of the microphone in the direction of motion of the diaphragm.

BNO Acoustics TR-12 Cut
1) One selection (one song) on a pre4ecorded music format.
2) A term with the same meaning as Mute (to turn off a channel or a signal).
3) To reduce gain of a particular band of frequencies (with an equalizer).
4) To not pass a particular band of frequencies (said of a filter)

Delay (Digital, Analogue)
1) Effect used to create echo…echo…echo…echo…echo…
2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.

BNO Acoustics GK-3 Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.

Harmonics
Integer multiples of a fundamental frequency, the fundamental itself being the first harmonic, its first overtone the second harmonic, etc. Attributing to instruments, voices, etc. their distinctive timbre.

Insulator
A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.

Attack
The rate the sound begins and increases in volume.
