Transients over time are muddled when an analogue sound is translated into a digital signal, a process known as temporal blurring. As a result, recorded music sounds flat when compared to 'live' music since our ears are unable to distinguish the sources of individual sounds. This distortion can be removed with MQA to produce the most accurate 3D soundstage ever heard.

How does MQA work?
Transients over time are muddled when an analogue sound is translated into a digital signal, a process known as temporal blurring. As a result, recorded music sounds flat when compared to 'live' music since our ears are unable to distinguish the sources of individual sounds. This distortion can be removed with MQA to produce the most accurate 3D soundstage ever heard.
