analog synthesis : See subtractive synthesis.
analog-to-digital converter : Commonly abbreviated A/D converter or just A/D. A device that changes the continuous fluctuations in voltage from an analog device (such as a microphone) into digital information that can be stored or processed in a sampler, DSP, or digital recording device.
analog sequencer : A sequencer into which sounds for storage and playback are fed as analog signals, via analog potentiometers.
analog recording : Any method of recording in which the recorded waveform is a continuous representation of the original signal, e.g., conventional magnetic tape recording.
analog : Capable of exhibiting continuous fluctuations. An audio signal is an electrical replica, or analog, of the waveform of the sound it represents. The voltage of the signal varies up and down (negatively and positively, in electrical terminology) the same way as the sound pressure varies up and down at the microphone. In an analog synthesizer, such parameters as oscillator pitch and LFO speed are typically controlled by analog control voltages rather than by digital data, and the audio signal is also an analog voltage. Compare with digital.
digital-to-analog converter : Commonly abbreviated D/A, D/A converter or DAC. A device that changes the sample words put out by a digital audio device into analog fluctuations in voltage that can be sent to a mixer, amplifier, or speaker. All digital synthesizers, samplers, and effects devices have DACs at their outputs to create audio signals, as the transducers in loudspeakers are inherently analog devices.
