Voice/Audio Quality Analyzer

The Objective Perceptual Signal Quality Analyzer setting the Standards

Comprehensive, end-to-end
quality analysis based on
perceptual measurement

The OPERA™Voice/Audio Quality
Analyzer represents the latest
developments to objectively eva­luate and assure the quality of
compressed voice and wide-band
audio signals, based on modeling
the human ear
can achieve a comprehensive ana­lysis of the end-to-end quality of
today's and next generation net
works, such as 3G V
VoATM, ISDN, GSM, POTS, from
the caller to the callee. Also, you
can test the audio quality of com
pression formats such as MP3,

-

AAC, AC3, Microsoft Windows
Media, from the studio source to
the receiver, or from the server to
the client.
For the test engineer, one of the
issues is how to apply a computer
model of the human ear to a test
circuit, or to a live network envi­ronment. For this reason, OPTICOM
developed OPERA as an open, easy
to configure hardware platform
that can process perceptual
models, which are implemented

-

just by software. The basis of the
OPERA system is a portable 'lunch

box' type of PC host system. Four
slots can take various kinds of
interfaces. Alternatively, OPERA is
now also available in a rack-moun­table form factor. For R&D and lab
applications, a cost effective soft­ware-only version with reduced
functionality is offered, as well.

Key Functionality at a Glance

Voice Quality
Measurement

• PESQ, the new state-of-the-art

perceptual evaluation of speech
quality according to ITU-T rec.
P.862 [2001], combines PSQM

AMS, optimized for VoIP

with P
and hybrid end-to-end applica­tions, MOS and MOS-LQ calcu­lations. PESQ wideband func­tionality (PESQ-WB) is also
included.
