When it comes to professional sound output, nothing beats the professional sound cards. The Professional sound cards are special sound cards that are optimized for low latency multi-channel sound recording and playback, including complete studio-grade fidelity. This enables the professionals to have the best sound output for such requirements.
The professional sound card drivers mainly follow the ASIO protocol for usage with professional sound engineering and music software, although ASIO drivers are also available for other general sound cards. Another aspect of the professional sound cards is that they are usually described as "audio interfaces", and sometimes have the form of external units using USB 2.0, Firewire or optical connectors to offer optimum data rates. The emphasis of the professional sound cards is to offer a large number of input and output connectors, hardware support for multiple input and output sound channels, as well as higher sampling rates and fidelity compared to a consumer soundcard.
The purpose of a professional sound card is to provide specialized multi-channel data recorder and real-time audio mixer and processor. This kind of output and performance is possible only to a very to a limited degree with general sound cards. The professional sound cards thus find limited use wit the home users and are designed for professional use only.
