It would be ridiculously easy to do this
Well then do so. You can give me a lift in your Ferrari if you ever manage to pull off that garbage you said.
By the way speaking of ridiculously easy, while you're at it, if you're so good at linearising then you must realise that a reverse of the transfer function is also easy to record and implement. Easier in fact. Also high speed PWM does what precisely through a low pass filter? Oh that's right, reproduce the soundwave. You can record the output of a class D amplifier too.
You get bonus points for posting that drivel to an article that fundamentally is complaining about the quality of sound. I mean there's plenty of people who just don't have a clue on Slashdot, but never have I seen someone not have a clue with so much conviction.
