  2. Comparison of analog and digital recording - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_analog_and...

    Early digital systems may have suffered from a number of signal degradations related to the use of analog anti-aliasing filters, e.g., time dispersion, nonlinear distortion, ripple, temperature dependence of filters etc. [20]: 8 Using an oversampling design and delta-sigma modulation, a less aggressive analog anti-aliasing filter can be ...

  3. Mixing console - Wikipedia

    en.wikipedia.org/wiki/Mixing_console

    Both digital and analog mixers rely on analog microphone preamplifiers, a high-gain circuit that increases the low signal level from a microphone to a level that is better matched to the console's internal operating level. In a digital mixer, the microphone preamplifier is followed by an analog-to-digital converter.

  4. Generation loss - Wikipedia

    en.wikipedia.org/wiki/Generation_loss

    Repeated conversion between analog and digital can also cause loss. Generation loss was a major consideration in complex analog audio and video editing, where multi-layered edits were often created by making intermediate mixes which were then "bounced down" back onto tape. Careful planning was required to minimize generation loss, and the ...

    The Digital Visual Interface (DVI) is a video interface standard designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors. It is designed for carrying uncompressed digital video data to a display. There are four basic connectors: DVI-D (digital only) DVI-A (analog only)

  6. Digital mixing console - Wikipedia

    en.wikipedia.org/wiki/Digital_mixing_console

    In professional audio, a digital mixing console (DMC) is a type of mixing console used to combine, route, and change the dynamics, equalization and other properties of multiple audio input signals, using digital signal processing rather than analog circuitry. The digital audio samples, which is the internal representation of the analog inputs ...

  7. Comparison of video codecs - Wikipedia

    The compression may employ lossy data compression, so that quality-measurement issues become important. Shortly after the compact disc became widely available as a digital-format replacement for analog audio, it became feasible to also store and use video in digital form. A variety of technologies soon emerged to do so.

  9. Sound card mixer - Wikipedia

    en.wikipedia.org/wiki/Sound_card_mixer

    Control channels Controlled source Wave / PCM stereo: Audio signal generated by the CPU via the sound card's digital-to-analog converter. (This includes audio produced by games, MP3 or WAV players, but also some software playing a CD-DA through the CPU, such as, Windows Media Player or Media Player Classic, as well as TV tuner cards that use the CPU for decoding audio.)
