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.
It is designed to help the live sound engineer optimize sound reinforcement systems before public performance and actively monitor acoustical parameters in real time while an audio system is in use. Most earlier analysis systems required specific test signals sent through the sound system, ones that would be unpleasant for the audience to hear.
One card may have a question (expression) and an answer (pronunciation, meaning). By keeping the separate cards linked to the same fact, spelling mistakes can be adjusted against all cards at the same time, and Anki can ensure that related cards are not shown in too short a spacing. A special note type allows the generation of cloze deletion ...
VDMSound allows the user to provide custom mappings for MIDI instruments as well as for joystick buttons and axes. MIDI mappings are particularly useful when the type of MIDI device supported by a game (e.g. MT-32) is different from the type of hardware or software device actually present on the system (e.g. Microsoft GS Wavetable SW Synth.)

Creative cards are generally backwards compatible with older EAX versions, although hardware accelerated DSP processing of these effects only happens on cards with EMU chips. Most audio solutions from Creative released after the X-Fi Titanium HD (except for the Audigy Rx) and other companies offer EAX software emulation of varying degrees instead.
AudioPCI itself was re-branded as several Creative Labs sound cards, including the Sound Blaster PCI 64, PCI 128, Vibra PCI, and others. The Ensoniq ES1370 audio chip was renamed Creative 5507 and revised into AC'97 -compliant variants, the ES1371 and ES1373, and used for several more years on card and as integrated motherboard audio.

Motherboards typically do not have any more than eight built-in output channels (7.1 surround sound) and four input channels (back and front panel microphone inputs, and a back-panel stereo line-in). Users requiring more audio I/Os will typically opt for a sound card or an external audio interface , as these provide additional features that are ...
