MQair - The New Scalable Hi-Res Codec For Mobile Devices

MQA Ltd has developed MQair, a new hi-res wireless codec that promises to deliver higher quality PCM and MQA audio files to wireless and Bluetooth devices.

First off, what's the difference between MQair and MQA? Apparently, MQair is a real-time delivery codec which is said to seamlessly scale up or down to deliver the best sound. Whereas the OG MQA is an audio tool for creating the “best original master”.

The new codec is officially dubbed SCL6, but MQA has given it the friendlier name of MQair for public use. SCL6 supports PCM and MQA audio formats up to 384kHz, over Bluetooth, Ultra-Wideband (UWB) and wi-fi streaming connections. Additionally, MQair claims to offer low latency and high efficiency, which should translate to better battery stamina from compatible wireless devices.

Furthermore, MQair has also been awarded the hi-res audio wireless certification from the Japan Audio Society (JAS). This gold stamp confirms hi-res audio status and can be found on products such as Sony headphones and portable players, as well as the Qobuz streaming service.

MQA says that MQair's detail and clarity are derived by focusing on the time domain. However, perhaps more important is that the encoded data rate is apparently scalable. We're told that MQair can scale from 20Mbps to below 200kbps low bitrates “seamlessly” in tiny increments.

From what we gather, other codecs take larger steps, and once they have lowered quality in response to a poor data rate, they will need to be restarted to take advantage of the better stream. But, that aside, taking smaller steps should mean we're far less likely to notice the changes in quality – so, no sudden jump down and a quicker response from the codec when the speeds improve.

Bob Stuart, MQA Founder & CTO, explains:

Many people want to enjoy the convenience of wireless connection to headphones or earbuds - especially 'on-the-go'. Invariably these wireless connections provide unpredictable data rates, and a codec is needed to bridge the gap. This 'bridge' can significantly reduce sound quality, especially if the source is high-resolution. MQair is a real-time codec that can seamlessly adapt to both the radio capacity and the music content and aims to maximise transparency.

As with all new codecs, it will be down to who adopts it and how easy it is for the end-user to consume it. It will certainly be interesting to see how long it takes before we see the MQair logo appearing on wireless devices. Moreover, we'll be keeping an eye on TIDAL to see if it takes the lead in supplying MQair to listeners, as it already uses the MQA format for its Masters hi-res offerings.

applause awards

Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.

Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.

The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.

We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
