The “Gigantic” Background The Tech Giant in question already had MultiDSLA systems when they approached us for a solution to process large quantities of recordings to provide voice quality and audio quality scores. This was clearly a requirement for MetricServer, Opale’s high-performance platform for bulk POLQA, PESQ and PEAQ processing applications. The first step was straightforward – the customer wanted …
This month’s Application Focus discusses the evolution of the EVS codec and two use cases applicable to wireless network operators. We begin with a short reminder of what EVS is, how it is being adopted around the world, and the potential – and challenges – it presents to network operators.

Check out this video ‘how-to’ to see how to get just what you want out of your MultiDSLA.
What’s it all about? The latest additions and improvements to the Opale Systems MetricServer platform bring the power of the ITU standardized metrics POLQA, PESQ and PEAQ to any organization wanting to take full control of its voice and audio quality optimization procedures. Read on to learn about automated processing using MetricServer with cross-platform Application Program Interface (API) support. Background: …
Application Focus In this new series we shall highlight some of the applications of the MultiDSLA system. The aim is to build a concise and practical guide to the many applications in which MultiDSLA delivers reference measurements around the world. We begin with the subject of Push-to-Talk. Why Push-to-Talk? Push-to-Talk, often referred to as PTT, is a form of wireless …
The Environment One of our North American Mobile Operator customers had been using MultiDSLA systems for several years, but one day presented us with a challenge. We like challenges, of course, so we were all ears. But when we saw the working environment, we were all eyes too! Inside a room easily large enough for 50 people to work in, …
“Do I really need POLQA?” The question is understandable, as the cost of POLQA can be a little greater than the cost of PESQ. MultiDSLA customers recognize great value and sometimes want to pursue it to the limit! Well, predictably, the answer is “It depends…” but to be more helpful Opale published a video outlining specific cases where POLQA is …
When a quick dash for the MOS is not enough The Task Sometimes that quick dash to fill a spreadsheet with Mean Opinion Scores (MOS) just won’t cut it. OK, we get it, your manager wants a report on the voice quality performance of widget X, so you reach for the test system. And MOS is great, because it figures …
