RE: "MQA sounds incredible" ~ What Does That Mean?

Posted by PAR on January 12, 2017 at 09:54:04:
Just , I hope, to clarify, MQA has two strategic components. The first is , as you say, to get a hi-rez file from a standard rez-carrier. That makes it sound a bit like like upsampling though, so for further further clarification, it is used to "pack" an actual hi-rez file within a standard rez carrier. To that extent it is not approprite to talk about MQA having a sound as the sound is effectively that of the hi-rez file.

However there is that second strategic component; the ability to correct aberrations caused by the digital filter when the recording was originally mastered. This is carried out when encoding. Going back to your earlier questions about making your own digital recordings e.g. from LPs, I would remark that this MQA process is only relevant to the correction of professional ADCs as it is the limited variety of these typically used in studios that makes it feasible for MQA to analyse their characteristics and to reproduce appropriate correcting algorithms.

The full MQA process involves the user's DAC also having a similar corrective process applied. Like the ADC process this requires MQA to "know" the DAC's digital filter characteristics hence the process is applied only within MQA equipped DACs.

As the "corrected" or " de-blurred" files (MQA calls the process rendering I believe) will differ from non de-blurred files then in this sense MQA does produce a unique sound, albeit dependent upon the original recording, which may reasonably be commented upon.
