My bro points out I did not mention a single flaw/example. (I am busy enough as it is) Besides things already mentioned by others, talking about dead regions, upwards spread of masking perhaps temporal scatter and tuning curves would have made it a lot more juicy. One flaw: time and volume are NOT self explanatory. Think about recruitment and such. Another flaw: multi-band compression is not doing what is suggested by the picture of the bear where the bicycle is missing. This visual example fits much better to a person with a dead region for whom frequency compression is applied. And this is not a one-size-fits-all method. Different techniques are available for this particular phenomenon (as there is frequency shifting as well). Anyway... let's mention a positive side. I appreciate the attempt of communicating on the topic and it was a good try to make things clearer for some. Better luck next time. Happy bro?
