Octave to Overtones
A difference of pitch where one tone has a frequency that is double or one-half of the frequency of another tone.
1) Away from the front or axis of the mic, measured in degrees.
2) 180 degrees from the front.
Offset (Offset Time)
1) The SMPTE time that will trigger a MIDI sequencer to begin.
2) The amount of position difference needed to get two reels to play the music in time.
The unit of opposition to current flow.
The mathematical relationship between voltage, current and resistance. >>> explanation
A prefix meaning All.
1) In microphones, picking up evenly from all directions.
2) In speakers, sending out evenly in all directions.

1) Video editing done by a computer controlling tape machines according programmed instructions and used for the final editing of video recording.
2) A status that means that the device is ready to receive input.
Short for Operational Amplifier (an amplifying circuit used in most audio devices).
