While some of you were predicting that MQA would wipe out in the clear PCM, and labels were out to convert your music to DRM, I kept saying none of this was true. That MQA simply lacked any kind of leverage to make your fears come true. It was a niche within a niche (a branch of high res music) which meant it was a fly on the back of the horse, not the horse itself.
OK, so here's where I differ. And why now I'm a lot more concerned about MQA than I have been in the past.
Let's go back to the 1990s. Meridian were involved in the aftermath of Ambisonics, a technology that was ahead of its time but of course failed, partly because of British government involvement as it happens. When they produced MLP, it seems to have been initially an idea to bring back Ambisonics as a digital format, but they got involved with the big boys. MLP is seen by us as the precursor to 5.1 Dolby audio on DVD. In fact, it was much more powerful than that and was designed with a future of multiple channels and all the technology being developed today. It's still there running Dolby Atmos and there's more in the tank, as it were.
Meridian were the first, or close to it, to bring DSP into home audio and demonstrate its value, and imagine its potential.
With Sooloos, Meridian were involved in the birth of streaming and at a very high level. Sooloos developers formed Roon and expanded on that promise.
In many ways, Meridian and Bob Stuart invented the digital audio world we live in today, more than Philips and Sony, more than Apple.
So, let's turn to MQA. Again, we think of MQA as the mess we see today. Lossy, kind of high resolution but somehow "not right", this proprietary codec that lets us mainly play stuff on a niche streaming service.
That's what it has become for now, but it's way, way more. Inside a 24/96 FLAC format or similar, it has space to be properly lossless. It could be put into a 32 bit container, making it absolutely lossless for 24 bit audio. It doesn't have to preserve a compatible section for playback on older devices at all. More importantly, the patent behind MQA patents two ideas: adapting the decoded musical data to the playback device, and a way to put control codes and metadata into audio channels.
If you consider the uses that those two ideas can be put to, the implications are huge. For example, a fully implemented MQA system could adapt the audio, compressing it on a car system, providing adaptive filtering for home systems. The metadata in the "folded" portion, which actually doesn't have to have audio in it at all, could be combined with MLP and audio steering technologies to go way beyond what Dolby Atmos is doing today. And the whole thing can be entirely proprietary and made available via one service, as could have been done with Pono and could still be done via something like Tidal.
And the SCL6 codec? They could have stopped at 4MB/sec, put the current codec into a few pairs of headphones and job done. No, again we see a technology designed to go much further (no doubt with a patent that could stop development of alternative protocols). It's seen in articles as "we can send 192/24 to headphones now", but I'm fairly sure that the bandwidth can be used for further improvement of spacial audio.
So here's the rub, as it were: we don't know who will own these powerful technologies next month, or how they will now be used. Potentially, with a market trained already to expect proprietary standards and separated streaming services through streaming video services, we could see a proprietary digital audio 3.0 develop: or maybe (I haven't followed some technology developments in this area) alternative ways have been found for everything MQA may do, already.
They will have a hard time converting existing music into this and making money, but a company that can release new music exclusively into a new format on a new service...
