I think the OPERA Voice/Audio Quality Analyzer represents the latest developments to objectively evaluate and assure the quality of compressed voice and wideband audio signals, based on modeling the human ear. With OPERA, you can achieve a comprehensive analysis of the end-to-end quality of today’s and next generation networks, such as VoIP, VoDSL, VoATM, ISDN, GSM, POTS. You can also test the audio quality of compression formats, such as MP3, AAC, AC3, Windows Media, from the studio source to the receiver, or from the server to the client.

With OPERA engineers can achieve a comprehensive analysis of the end-to-end quality of today’s and next generation networks, such as VoIP, VoDSL, VoATM, ISDN, GSM, POTS, from the caller to the callee. 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.
