Perceived Differences in Timbre, Clarity, and Depth in Audio Files Treated with MQA Encoding vs. Their Unprocessed State

(Subscribe to this discussion)

Document Thumbnail

The purpose of this engineering brief is to detail a planned experiment in examining any perceived differences in timbre, clarity, and depth between WAV and Master Quality Authenticated (MQA) audio files. A study proposes examining the responses of engineers, musicians, and casual listeners on whether any changes to timbre, clarity, and depth are perceived between WAV and MQA. A blind listening test is considered in a controlled environment using both professional and consumer level loudspeakers and headphones. Additional interests include a comparison of responses between the target groups on different listening mediums.

How do you plan to ensure that the exact same master is used for both MQA and WAV files?

Some Tidal streaming tracks appear to use different masters

Best regards

We will be using our own sources, not Tidal, and we have examples of pre- and post-MQA processing for each source.

Thank you
