It turns out that the only thing you need to do to make people crazy is post a video showing a niche micro SD card Music format imported from South Korea. My original mission was to showcase a product that many won't have seen before, but I feel I inadvertently have found a way to turn man against man. I think this video could be weaponised and deployed into enemy countries as a way to destabilise them and ultimately topple governments.
MQS SD is sold in South Korea & HK for use with the Astell & Kern Hi-Res Personal Audio Players which feature MicroSD card storage slots.
Astell & Kern use MQS to define HD Audio in a FLAC format with a 24bit encoding. According to their specs the KHz sample rate can vary depending on the source between 48KHz and 192KHz. The Beatles LP seems to be a special case because it’s just 44.1 KHz and I suspect this is because that’s the best source currently available.
Back in 2014 manufacturers and record companies got together to define a system to code HD audio files. Here’s what they came up with.
MQ-A - Taken from an Analogue Master Source
MQ-C - Sourced from a 16bit 44.1KHz CD master and upsampled
MQ-D - Sourced directly from a Direct Stream Digital DSD Master
MQ-P - Sourced from a minimum 20bit master with a minimum 48KHz sample rate
I haven’t seen these in use anywhere since, perhaps they were considered too complicated when you then combine them with the filetype AIFF, ALAC, FLAC or WAV.
So what is MQS? Well as the video shows it’s not exactly nailed down in A&K’s description and I suspect that it’s just a simplification of the existing system.
If you look at this South Korean music download site http://www.groovers.kr/mqs/chart/dome... you can see they use MQS to identify HD tracks and then use a code like MQS 24/192 to identify the quality. The logo stands out in red on the page and the system is slightly simpler than stating a file is “HD Audio MQ-D FLAC 24/192”
Whether the average human ear is capable of hearing the difference between all these things - I haven't a clue and I don't have a horse in that race...I'm just interesting in collecting formats.
SNAKEOIL - It's a flippant joke at the vague definition of the benefits of MQS over normal FLAC HiRes audio files...is there really any difference? It appears MQS is just 24 bit FLAC.
I AM NOT SAYING HI-RES AUDIO IS SNAKEOIL ...just that I can see no discernible technical differences between 24 bit FLAC and MQS. Perhaps there is one...and if so A&K need to do a better job of defining exactly what the specific benefits of MQS difference are.
Here is a link to all the MQS SD Card Albums.
I bought my Beatles MQS SD Album on ebay - here's a link that should find any for sale https://goo.gl/MMOKDM
Don't overpay though!
Incidentally there's also another file format called MQA - here's some info on that http://www.soundandvision.com/content... This seems to have no connection to the MQ-A categorisation I mentioned above (which describes the origin of a recording - like AAD or DDD you used to see on CD's) This MQA (without the dash) actually seems to be a separate format that is backwardly compatible with some other formats...it's all very confusing.
To make things easy, feel free to copy and paste one of the following stock responses.
This won't sell
I won't buy this
This will get lost
I can download music to put on my own MicroSD card
Physical media is dead
This isn't a physical format
This is nothing new
What happens if you delete the files off the card (?!?)
HiRes audio is nonsense
