The OPERA
™
Voice/Audio Quality
Analyzer represents the latest
developments to objectively eva-
luate and assure the quality of
compressed voice and wide-band
audio signals, based on modeling
the human ear. With OPERA you
can achieve a comprehensive ana-
lysis of the end-to-end quality of
today's and next generation net-
works, such as 3G VoIP, VoDSL,
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 envi-
ronment. 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-moun-
table form factor. For R&D and lab
applications, a cost effective soft-
ware-only version with reduced
functionality is offered, as well.
Supported Operating Systems
are Microsoft Windows NT

,
Windows

2000, Windows
