A lot of monitors have a natural hiss present from their amplifiers, ie hissing/noise floor/white noise sound. Class A/B monitors are better in this regard for being silent but they are run hotter and are not as commonly used in budget things.
Could Sonarworks have a new feature to calibrate this flaw OUT of them using noise cancellation?
Wikipedia simply states that A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference.
Would this be possible? Sonarworks already has a meter built in to tell when it's getting a signal (Sonarworks Virtual Audio Device), so it could only apply this correction when it detects no or low volume. Would the measurement microphone even detect phase? If this was possible and worked, I would buy it in a second. It could really entice anybody to calibrate their speakers, or at the minimum, turn on hiss removal (you should split the two things, like how listening spot is split from calibration).
