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.
Although there is a degree of functional overlap, audio interfaces are differentiated from audio mixers in that they are intended to pass multi-channel audio directly to a host digital audio workstation, whereas mixers generally sum their inputs into a simple two-channel stereo pair. Audio interfaces are therefore often simple rackmount boxes ...
VIVO on these graphics cards typically supports Composite, S-Video, and Component as outputs, and composite and S-Video as inputs. Many other video cards only support component and/or S-Video outputs to complement Video Graphics Array or DVI, typically using a component breakout cable and an S-Video cable.
According to a USB-IF chairman, "at least 10 to 15 percent of the stated peak 60 MB/s (480 Mbit/s) of Hi-speed USB goes to overhead—the communication protocol between the card and the peripheral. Overhead is a component of all connectivity standards". [1] Tables illustrating the transfer limits are shown in Chapter 5 of the USB spec.
The USB Device Class Definition for MIDI Devices transmits Music Instrument Digital Interface music data over USB. [123] The MIDI capability is extended to allow up to sixteen simultaneous virtual MIDI cables, each of which can carry the usual MIDI sixteen channels and clocks. USB is competitive for low-cost and physically adjacent devices.
A number of extensions to the USB Specifications have progressively further increased the maximum allowable V_BUS voltage: starting with 6.0 V with USB BC 1.2, [43] to 21.5 V with USB PD 2.0 [44] and 50.9 V with USB PD 3.1, [44] while still maintaining backwards compatibility with USB 2.0 by requiring various forms of handshake before ...
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.)
Sound Blaster Audigy is a product line of sound cards from Creative Technology. The flagship model of the Audigy family used the EMU10K2 audio DSP, an improved version of the SB-Live's EMU10K1, while the value/SE editions were built with a less-expensive audio controller. The Audigy family is available for PCs with a PCI or PCI Express slot, or ...
