Yamaha Announces Audio Codec IC That Offers High-Quality Audio and Voice for
Mobile Devices

TOKYO, June 11 /PRNewswire/ -- Yamaha Corporation (TSE 1st Section 7951,
Headquarters: 10-1 Nakazawa-cho, Naka-ku, Hamamatsu, Shizuoka; President:
Mitsuru Umemura; hereinafter, Yamaha) has announced the development of its
YMU809 audio codec IC that brings high-quality audio processing and hands-free
functions to personal navigation devices (PNDs), mobile phones, and other
devices. Yamaha plans to begin sample shipments of the YMU809 ICs on June 12,
2008.
In recent years, sales of PNDs featuring hands-free functions are
expanding. And demand for improvement of voice sound quality in mobile phones
is also rising. The YMU809 improves voice sound quality of mobile devices. In
addition to offering high-quality, high-performance audio processing, which is
based on Yamaha proprietary AudioEngine(TM) technology, it incorporates
echo-canceling and noise-suppression functions that minimize the sound-quality
deterioration that occurs in hands-free telecommunication. By integrating all
the necessary functions for sound, which is audio and voice, the YMU809 can
offer an easy-to-use system for PND, mobile phone and other devices.
Yutaro Nakano, Director of Sales of Yamaha's semiconductor business,
commented, "The YMU809 is an input/output device for a broad range of audio
and voice sources handled by mobile devices, including phone voice, navigation
voice, music, video and broadcast. We believe there will be major demand for
the YMU809 in the mobile device market."
Principal Features of the YMU809

1. Built-in, high-quality audio processing based on AudioEngine(TM)
technology
Incorporates a wealth of high-sound quality, high-performance functions
that give high-quality sound output through small-diameter speakers and
headphones, including surround acoustic field processing for
multi-channel audio. Also, it incorporates compressed audio decoders
for low power consuming devices.

2. Built-in, hands-free operation and other functions for improvement in
quality of conversational voice processing
Incorporates hands-free functions, such as echo canceling and noise
suppression, are optimized for PNDs and mobile phones. The noise
suppression function operates for both transmitting and receiving, and,
used in combination with the speech speed control function and voice
quality improvement functions based on AudioEngine(TM) technology, the
YMU809 can provide voice transmission and reception that is clear and
easy to understand even in noisy environments.

3. Total management of sound output and input
Incorporates audio quality ADC/DAC, a mixer and wider range of analog
and digital inputs/outputs so that the YMU809 can manage all types of
audio and voice sources handled by mobile devices.
