A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Runs on Microsoft Windows. Supports most all HTML5 devices as remote controls. Asset UPnP (DLNA compatible) from Illustrate. An audio specific UPnP/DLNA server for Windows, QNAP, macOS and Linux. Features audio WAVE/LPCM transcoding from a range of audio codecs, ReplayGain and playlists.
An audio interface is a piece of computer hardware that allows the input and output of audio signals to and from a host computer or recording device. Audio interfaces are closely related to computer sound cards , but whereas sound cards are optimized for audio playback an audio interface is primarily intended to provide low-latency analog-to ...
Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.
In hardware, audio codec refers to a single device that encodes analog audio as digital signals and decodes digital back into analog. In other words, it contains both an analog-to-digital converter (ADC) and digital-to-analog converter (DAC) running off the same clock signal. This is used in sound cards that support both audio in and out, for ...
An example of DIY audio: a functioning battery-operated DAC (Digital-to-analog converter) before installation in a box case. DIY Audio, do it yourself audio.Rather than buying a piece of possibly expensive audio equipment, such as a high-end audio amplifier or speaker, the person practicing DIY Audio will make it themselves.
The clock rate of the PC's programmable interval timer which drives the speaker is fixed at 1,193,180 Hz, [3] and the product of the audio sample rate times the maximum DAC value must equal this. Typically, a 6-bit DAC [8] with a maximum value of 63 is used at a sample rate of 18,939.4 Hz, producing poor but recognizable audio. [9]
The devices listed in the Multimedia/Sounds and Audio control panel applet represent the MME API of the sound card driver. The Multimedia Extensions (WaveIn/WaveOut interfaces) were released in autumn 1991 to support sound cards, as well as CD-ROM drives, which were then becoming increasingly available.
