Space Echo
An effect of repeating echoes of a sound.

Scrub
The action or function of shuttling (moving the sound track) usually of digital audio, either forward or backward when a control is moved off a center point either left or right.

Trap
A filter designed to reject audio signals at certain frequencies.

BNO Speakers: Terminal
1) A point of connection between two wires including a device on the end of a wire or cable that allows attachment and the accepting point on a case of the equipment.
2) A computer keyboard and monitor that allows access and entry of information into or from a computer.

BNO Acoustics SQ-9: Clean
Describes a distortion free sound with few effects.

BNO Acoustics BP-40: Slate
1) The voice recorded onto the beginning of a master tape to identify the tune and take, or the action of making it.
2) The circuit or control which allows you to slate masters.
Slave The transport, which adjusts speed to be in time with the master transport when two machines are synced together.

BNO Acoustics 6k-52: Cycles Per Second

A unit used in the measure of frequency, equivalent to Hertz. Cycles Per Second is an outdated term replaced by Hertz in 1948.

Print
1) The action of a Print Through (unwanted transfer of magnetic flux from one layer of tape to another).
2) To record (slang definition).

BNO Acoustics QT-5: Touch Sensitive
Capability of a synthesizer keyboard to generate a velocity MIDI signal. Not all synthesizer keyboards are touch sensitive.

BNO Acoustics GK-3: Recordist
A person operating recording equipment as a hobby or non-professionally.

Wet
Having reverberation or ambience.

BNO Acoustics XV-16: Magnetic Tape
Recording tape consisting of a plastic strip to which magnetic materials, usually in form of finely ground iron oxide (rust) particles, are adhered.

Tie Lines
Cables with connectors at both ends, usually run through walls or floors, so that a signal can be sent or picked up from some remote location.

BNO Acoustics LK-61: Subcode

Control information bits that are recorded along with digital audio and can be used for control of the playback deck (functions as program number, start ID's, skip ID's etc.).

Medium Delay
Delay times of 20 ms. � 60 ms.

Multitrack Recording
1) A technique of recording various instruments separately on different portions of the same tape, in time with each other and so that final balancing of the sound may be accomplished later.
2) A technique of digitally recording various instruments onto a hard disk in different data files so the may be played in time with each other and final balancing of the sound may be accomplished later.

Measure
The grouping of a number of beats in music.

Input Monitor
A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal.

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

Playlist
A series of computer commands to a disk recording of digital audio where the playback of the digital audio is to play certain portions and not others.

BNO Acoustics 6k-52: Signal-to-Error Ratio

The level difference between the signal and the noise and distortion caused by converting analog audio signals into digital audio and then back into analog.

Blending
1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance.
2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are not panned extremely left or right.

BNO Acoustics XR-90: Quality Factor
The ratio of reactance to resistance in a coil which affects Q.

Portamento
1) A pitch change that smoothly glides from one pitch to another.
2) The synthesizer mode or MIDI command that allows or causes this to happen.

Release Time
The time it takes for a dynamics processing device to change gain when the input signal crosses the threshold level while decreasing.

Noise Filter
A filter used which passes only signals with the intended audio frequencies thus eliminating noise signals at other frequencies.

Virtual Tracking
Having a MIDI sequencer operate in sync with a multitrack tape and controlling the playing of synthesizers along with the recorded parts.

BNO Acoustics QS-4: Sound Absorption

Same as Acoustical Absorption (the action or quality of a surface or substance to absorb sound rather than reflect it).

Peak Indicating Meter
A meter which reads the absolute peak level of the waveform.

Active Crossover
Uses active devices (transistors, IC's, tubes) and some form of power supply to operate.

BNO Acoustics GK-3: Bass Roll Off
An electrical network built into some microphones to reduce the amount of output at bass frequencies when close-micing.

Compact Disc, Read Only Memory CDROM
A Compact Disc used to store digital data, such as large programs, that can be read by a computer.

Frequency
Practically speaking, high frequency means high pitch and low frequency means low pitch.

TT
A trademark of Switchcraft and meaning Tiny Telephone Jack/Plug (A smaller version of the phone jack/plug).

BNO Acoustics SQ-9: Spaced Pair

Any two microphones spaced to get a stereo pickup especially using the Spaced Omni or Spaced Cardioid techniques.

Tension Switch
A switch that reduces torque to the reel motors for small reels and allows full torque for larger reels.

Cardioid Pattern
A microphone pick up pattern, which has maximum pick up from the front, less pick up from the sides, and least pick up from the back of the diaphragm.

BNO Acoustics BP-40: Talkback
The system which allows the engineer to talk into a microphone in the control room and have his voice come over the studio monitors and/or headphones so he can talk to the musicians.

Reverb (Reverberation)
1) A shortening of the term Reverberation (the persistence of a sound after the source stops emitting it).
2) Effect which may be added to sound effects during recording or to a voice during performance. Sustains the sound longer than normal, as if the sound was reverberating around a large building (e.g. cathedral). Persistence of sound after the source has ceased.
3) Adding the acoustics of a concert hall.
4) A most basic and necessary effect. Think of it like this. If you stand in a big empty warehouse and shout, "Hey!", you will hear a sort of "reverberation" surround you. It's sort of like an echo, but not exactly. Think of it as audio afterglow.

Attenuation
A making smaller: reduction of electrical or acoustic signal strength.

Telephone Jack
The full and more formal name for the term Phone Jack (a jack taking a plug with a diameter of 1/4 inch and a length of 1 1/4 inches; used for interconnecting audio).

Short for the term Echo Return or Auxiliary Return (the input of the console which brings back the effects signal from the echo chamber or other reverberation effects device).
