TAS3xxx and TAS55xx Digital Audio Processors and Third-Party Algorithms
Texas Instruments’ family of digi-tal audio processors offers manu-facturers a wide range of audio processing capabilities, including, integration with TI's PurePath™digital amplifiers. The TAS3xxx and TAS55xx digital audio proces-sors bring the sound quality of an expensive, high-end A/V receiver to an affordable cost level for con-sumers of home theater-in-a-box systems, flat panel television ts, micro- and mini-component stereos, and other consumer elec-tronic products.High-End Sound Quality
应用型论文
This family of digital audio
processors offers the highest res-
olution for a full and rich digital
sound experience. The TAS3103,
TAS5504 and TAS5508 devices
feature a full 48-bit audio data-
path while the TAS3002 has a 32-
bit architecture for true CD- and
DVD-quality sound.
In addition, the digital audio
processors have a configurable
architecture that accommodates
the rapid deployment of
preconfigured audio processing
functions and enhanced sound
algorithms from TI and third par-
ties. A wide variety of algorithms
and functions such as loud-
speaker normalization, cond-
order tone control, triple slope
dynamic range compression, auto

mute, 3D sound, virtual surround
sound and various loudness
curves are readily available.

When the Market Won’t Wait
The configurable architecture of TI’s digital audio processors sup-port the demands of consumer electronics (CE) manufacturers who must bring products to mar-ket very quickly. With pre-programmed sound-processing algorithms from third parties and TI, CE manufacturers are able to rapidly respond to changing demands or new preferences as they emerge in the marketplace.For ex
ample, one major manu-facturer of consumer electronics products and audio systems,recently brought a new audio product to the marketplace in the record-tting time of just three months. The system featured TI’s
Selected Third-Party Audio Processing and Sound Enhancement Algorithms for the TASxxxx Audio Processors
NOTE: Not all algorithms are available on all TASxxxx audio processors. Contact TI for the availability of specific algorithms. The following list of algorithms reprents a sample of tho that are available on TI's TASxxxx audio processors at any one time.
TAS5508 digital audio processor/ PWM processor in an innovative bundling with third-party sound enhancement algorithms from SRS®Labs, Inc. The licensing bundle was put together to streamline the typical develop-ment cycle and shorten the sys-tem’s time-to-market. TI’s digital audio support personnel worked cloly with SRS Labs to meet the project’s three-month timeframe.
“We’re accustomed to fast turnaround times in the consumer electronics space,” said Joanna Skrdlant, director of emerging markets and platform develop-ment of SRS®Labs, “but this par-ticular project with TI was exceptionally fast. The project demonstrated the value of prepro-grammed, TruSurround XT™ vir-tual surround sound functionality and a compatible hardware archi-tecture capable of outstanding sound quality. In the end, all of the pieces fell into place and the parties involved benefited from
the project.”
TI has earned a reputation for
the extensive resources that sup-
port manufacturers’ custom
design projects. The company has
implemented a focud design
and support model comprid of
engineering, production, manu-
facturing and sales personnel.
Many OEMs like Panasonic, JVC,
Kenwood, Harman/Kardon, Jamo,
证成LG Electronics, Pioneer, RCA,
Koss, Samsung and others have
taken advantage of TI’s extensive
support for its portfolio of digital
audio technology to deliver their
products to a consumer electron-男的干女的
ics marketplace that changes
everyday.
Comprehensive Digital Audio
Components
TI offers a complete suite of digi-
tal audio technology which gives
manufacturers the freedom to
design a broad range of systems
that meet a variety of cost and
performance targets. Many func-
tions previously unrealizable or
available only through analog
components are now performed
in the digital domain with a new
level of ea and flexibility.
TI’s audio components offer
manufacturers the widest dynamic
range and exceptional sound
fidelity along with highest degree
of integration to simplify system
