Progress Being Made Towards High Definition Audio

Finally! The recording and music industry is discussing standards and practices for proper high-resolution audio, which will hopefully lay the groundwork for mass acceptance by consumers.

This is 20 years past due. Better late than never.

All of this vibration won't compress to 256k.

All of this vibration won’t compress to 256k.

The various entities are having trade shows, panel discussions, demonstrations, and are talking standards, consumer education, and branding for music of all qualities.

Here’s an overview of the talks taking place.

Here is another tech overview.

Here is a mainstream consumer view on it.

The keys here are A) provenance and B) final resolution.

Provenance covers the origin of the recording while final resolution is what you are actually being sold. How it got from A to B is important when pushing quality and asking consumers to buy something that many have devalued.

The industry has recommended the following grades that they are calling Master Recording Qualities:

  • MQ-A: From an analog master source
  • MQ-C: From a CD master source (44.1 kHz/16 bit PCM digital), could be up-sampled
  • MQ-P: From a PCM master source that is 48kHz/20 bit PCM or higher (typically 96/24 or 192/24)
  • MQ-D: From a DSD/DSF master source (DSD encoding)

Similar to the 3-letter code on vinyl telling you if it’s sourced from analog or digital, this should inform the consumer and allow the labels to sell guaranteed quality.

This could be a big step towards the mainstream adoption of high resolution audio (HRA).

 

Note: This has nothing to do with Meridian’s new encoding format dubbed MQA (their acronym for Master Quality Assurance, I think) which is built to be a replacement for PCM, the encoding used for most digital audio. If anyone ever records in MQA, it could perhaps become MQ-M above.
