Microsoft's UAA (Universal Audio Architecture). The ALC883 series provide 10 DAC
channels that simultaneously support 7.1 sound playback, plus 2 channels of independent
stereo sound output (multiple streaming) through the front panel stereo output. Flexible
mixing, mute, and fine gain control functions provide a complete integrated audio solution
for home entertainment PCs.
The ALC883 series also integrate two stereo ADCs that can
support a stereo microphone
with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression
(NS)
technology simultaneously.
All analog IO are input and output capable, and headphone amplifiers are also integrated
at each analog output. All analog IOs can be re-tasked according to user's definitions, or
automatically switched depending on the connected device type.
The ALC883 series support 16/20/24 S/PDIF input and output to offer easy connection of
PCs to high quality consumer electronic products such as digital decoders and speakers.
The ALC883 series support host/soft audio from the Intel ICH series chipset, and also from
any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D
compatibility, and excellent software utilities like Karaoke mode, environment emulation,
software equalizer, HRTF 3D positional audio, and optional Dolby® Digital Live and DTS®
Connect program, the ALC883 series provide an excellent entertainment package and
game experience for PC users.
