Auzentech, Inc. was aKoreancomputer hardware manufacturer that specialized in high-definition audio equipment and in particular PCsound cards.

Auzentech has its origins in March 2005, when under the company nameHDA (HiTeC Digital Audio),^[2] the company launched the X-Mystique 7.1, the first consumer add-in sound card to featureDolby Digital Live.Initially only a manufacturer, HDA's products were commercialized worldwide by a network of local distributors, includingBlueGears as their vendor in theUnited States.^[3][4][5]

In 2006 the company took distribution into their own hands, ceasing relations with BlueGears, and subsequently changing their brand name toAuzen (a name which originates from "Audio" and "Zen")^[4] and their company name toAuzentech.^[6]

Since that time the company continued to incorporate new sound cards into their lineup in an effort to compete in a market dominated byCreative Labs.^[7] Auzentech sought to provide customers with features not present in Creative's sound cards at that time, such as real time multi-channel audio encoding and built-inTOSLINK connections.^[8] These features enable users to have multichannel realtime audio (like that originating in PC games) over a single digital line, instead of the previously unavoidable three analog lines running from the PC to the speakers. Also present in all Auzentech sound cards are user-replaceableopamps,^[9] which offer the possibility to further improve the out-of-the-box quality ofanalog outputs.

Eventually expansion led Auzentech to broaden their range of products to include items such asspeakers,microphones andPC cases among others.

Auzentech has recently switched from theC-Media audio processors used in their earlier cards to theX-Fi audioDSP, licensed from their competitor, Creative Labs.

Since early 2014, Auzentech's official web site has been directing to a park page, and their technical support department ceased to provide any service.
