You are wrong there I assume you, as a programmer, are fairly knowledgeable in the field of physics? Therefore you understand the concept superposition? Well, even if you cannot directly hear frequencies above the 20Khz threshold, the waves above the 20Khz threshold can superpose the waves below the threshold and thus actually can have an effect on the audible sound. Simple physics.PokeParadox said:Also yes Vinyl captures the full sound, but all of the frequencies are captured meaning there are many frequencies which are redundant due to the limitations of the human ear. The developers of MP3 and AAC take that into consideration and throw much of the redundant frequencies away. Yes their judgement of what may be considered redundant might not suit all ears, but they are continually refining this based on blind audio tests.
