2. Digital-to-analog converter - Wikipedia

   en.wikipedia.org/wiki/Digital-to-analog_converter

   Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application. DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals ...

3. 1-bit DAC - Wikipedia

   en.wikipedia.org/wiki/1-bit_DAC

   A 1-bit DAC (sometimes called Bitstream converter by Philips) is a consumer electronics marketing term describing an oversampling digital-to-analog converter (DAC) that uses a digital noise shaping delta-sigma modulator operating at many multiples of the sampling frequency that outputs to an actual 1-bit DAC (which could be fully differential to minimize crosstalk). [1]

4. Analog-to-digital converter - Wikipedia

   en.wikipedia.org/wiki/Analog-to-digital_converter

   Analog-to-digital converters are integral to modern music reproduction technology and digital audio workstation-based sound recording. Music may be produced on computers using an analog recording and therefore analog-to-digital converters are needed to create the pulse-code modulation (PCM) data streams that go onto compact discs and digital ...

5. Audio converter - Wikipedia

   en.wikipedia.org/wiki/Audio_converter

   Dedicated hardware devices, such as digital audio converters (DACs) and audio interfaces, can convert audio signals from analog to digital or vice versa. These devices are often used in professional audio settings, such as recording studios, to maintain high-quality audio signal integrity.

6. Delta-sigma modulation - Wikipedia

   en.wikipedia.org/wiki/Delta-sigma_modulation

   Delta-sigma (ΔΣ; or sigma-delta, ΣΔ) modulation is an oversampling method for encoding signals into low bit depth digital signals at a very high sample-frequency as part of the process of delta-sigma analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

7. Digital audio - Wikipedia

   en.wikipedia.org/wiki/Digital_audio

   In a digital audio system, an analog electrical signal representing the sound is converted with an analog-to-digital converter (ADC) into a digital signal, typically using pulse-code modulation (PCM). This digital signal can then be recorded, edited, modified, and copied using computers, audio playback machines, and other digital tools.
