BNO Acoustics TR-12: Truncation
The editing of a sample playback so that just the desired portion of the sample is played by moving the start and end point of the sample playback.
Voltage
The electrical force pushing electrons to obtain electrical current.
Atom
The smallest particle which makes up a specific substance. It's composed of a center around which electrons revolve.
Regulated Power Supply
A device to supply power to electronic equipment whose output voltage will not fluctuate when more equipment is turned on, or if there is a change in voltage of the power line.
Integrated Circuit (IC)
A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.
Width
Another term for Depth (the amount of change in the controlled signal by the control signal).
Feedback
1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects.
2) The pickup of the signal out of a channel by its input or the howling sound that this produces.
3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise.
4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics�and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA.
