Digital Signal Processing - Any signal processing done after an analog audio signal has been converted into digital audio.
Digital To Analog Converter - A device to change digital data numbers that make up the digital audio into discrete voltage levels that approximate the original analog audio waveform.
Direct - 1) Using a direct pickup. 2) Using a direct output. 3) Recording all musicians to the final two track master without using a multitrack tape.
Direct Box - An electronic device utilizing a transformer or amplifier to change the electrical output of an electric instrument (for example, an electric guitar) to the impedance and level usually obtained from a microphone.
Direct Input - A term meaning the same thing as the term Direct Pick Up (feeding the signal from an electrical output of an electric instrument to the recording console or tape recorder without using a microphone but by changing the electrical output of the instrument to the impedance and level of a microphone).
Direct Pick Up - Feeding the signal from an electric instrument to the recording console or tape recorder without using a microphone.
Direct Sound - The sound which reaches a microphone or listener without hitting or bouncing off any obstacles.
Directional Pattern - 1) In microphones, a term meaning the same thing as the term Pick Up Pattern (a description or graphic display of the level that a microphone puts out because of sounds arriving from different directions). 2) In speakers, the pattern of dispersion (the area that the sound from a speaker will evenly cover in a listening area).
Distortion - 1) The audio garble that can be heard when an audio waveform has been altered, usually by overload of an audio device like an amplifier. 2) The similar garbled sound that can be heard when the sound pressure level is too loud for the waveform to be accurately reproduced by the human hearing mechanism.
Double - 1) To record a second performance, double tracking (recording a second track with a second performance, closely marching the first performance). 2) To use a delay line with medium delay to simulate this.
