Wow thanks fletcher. i think thats pretty much what i already sort of had in mind......in essence, we need to record these inaudible frequencies because in the end although these frequencies may not be heard, they are "heard."
i know that sounds weird but its something you can hear if its not there vs. when it is there. The same teacher also mentioned in class that it is probably a better idea if were recording at 24 bit to use 88KHz instead of 96KHz to make the computer be able to utilitze info better without having to go down to decimals where everything will work out evenly, is this true and is there any significant loss of quality with a small jump like that?
