Do you want to compare reference and test audio to evaluate the quality in your own language, but don’t have a tool?
AQuA is an audio quality analyzer that gives you even more flexibility:
✔️Language Independence – AQuA can evaluate quality of audio in any language.
✔️Long and short calls support – analyzes audio shorter than 4 seconds and longer than 30 seconds.
✔️Works with Stereo Audio – test signals may be mono or stereo, narrow, wideband and super wideband.
✔️Allows parameters profiling – configurable perceptual model that best suits your test environment.
Are you into conversational analysis?
Do you have millions of call recordings that you like to range based on audio quality?
Sevana PVQA is the tool that can analyze hours of recorded audio in a couple of minutes.
Request a call with our team to learn more about call recordings quality analysis and other related technologies for audio quality assessment.
Sevana QualTest is a mobile testprobe GSM VoIP application that checks current network conditions and estimates voice quality in mobile and VoIP networks. The platform is designed for end-to-end and single-end call testing, as well as for gathering and analyzing call audio quality metrics. Measure network metrics for VoIP calls and use waveform analysis to correlate audio problems with network conditions.
Being a multipurpose tool for voice quality analysis PVQA Server can be the core of a quality analysis and monitoring system to detect and investigate QoE and QoS related issues. PVQA Server combines the force of audio waveform analysis using PVQA technology with continuous network monitoring:
🔎Real-time call quality monitoring
🔎Proactive maintenance based on non-intrusive waveform analysis
🔎Monitoring network and media quality simultaneously
🔎Matching network metrics (RTT, jitter, latency, packet loss) with payload metrics (noise, clipping, dead air, echo etc)
Voice quality is the term used to describe the clarity of your voice. It’s more than just the sound of your voice—it also includes things like background noise and interference, which can have an adverse effect on how well your voice is heard. This makes passive voice quality testing and analysis and important part of modern communications.
Network operators may reduce network operations costs by up to 65% using automation at the IP domain layer. Analysys Mason partnered with Nokia to conduct in depth operator interviews to reach this conclusion. We believe that one can significantly reduce costs also on test automation and call quality monitoring using Sevana QualTest and PVQA Server.
We would like to announce pre-release of new versions of AQuA and PVQA that introduce Machine Learning engine integrated into both technologies. With these new tools our customers now can train perceptual models of AQuA and PVQA to provide MOS (Mean Opinion Score) scores that better conform real user quality of experience. Please contact us for demonstration and evaluation.
Register to our webinar on how to measure caller’s quality of experience (QoE).
This time we’ll show how to setup an end-to-end call quality testing and monitoring in mobile networks.
We’ll present and discuss QualTest GSM, show how one can turn an ordinary Android smartphone into a mobile test probe, demonstrate standard (3G / 4G / 5G) agnostic end-to-end test calls, and how the QoE metrics are collected and aggregated by QualTest solution.
