BNO Speakers: Nybble

One half byte, 4 information bits.

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

BNO Acoustics 6k-52: Synthesizer
A musical instrument that artificially (using oscillators) generates signals to simulate the sounds of real instruments or to create other sounds not possible with real instruments.

Infinite Repeat
A function on some delay lines that establish enough feedback so that the repeat echo will last forever, but not so much as to cause a howling sound.

BNO Acoustics BP-40: Effects
1) Various ways an audio signal can be modified by adding something to the signal to change the sound.
2) Short for the term Sound Effects (sounds other than dialogue, narration or music like door closings, wind, etc. added to film or video shots).

Error Detection
The process of discovery that sonic information bits have been lost in digital audio.

BNO Acoustics QT-5: Impedance
1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms).
2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value.
3) The opposition to alternating current.
