BNO Acoustics LK-61: Shelf

A frequency response of an equalization circuit where the boost or cut of frequencies forms a shelf on a frequency response graph. A High-Frequency Shelf control will affect signal levels at the set frequency and all frequencies higher than it; a Low-Frequency Shelf control will affect signal levels at the set frequency and all frequencies lower than it.

Loop
1) A term meaning the same as Anti-Node (the points of maximum displacement of motion in a vibrating stretched string).
2) A tape (or magnetic film) recording where the ends of the tape are spliced together in such a manner that the tape will continually repeat.
3) A repeating of an audio sample with no gap in between.

Horn
1) The part of the speaker that emits midrange and higher range frequencies.
2) A speaker or speaker enclosure where sound waves are put into a narrow opening (by a speaker cone or driver) and the narrow opening flairs out to a larger opening.

File
A collection of digital data stored in a computer's memory bank or on a floppy disc.

BNO Acoustics XR-90: Phase Reversal
A change in a circuit to get the waveform to shift by 180 degrees.

BNO Acoustics BP-40: Lift
1) To boost gain of audio at a particular band of frequencies with an equalizer.
2) An elevation device in the star trek series of TV programs.

Sample Rate Conversion
The conversion of digital audio at one sample rate to digital audio at a different sample rate without first converting the signal to analog.
