tebasuna51, I can get the rough idea what you said above...
But I don't get the point of down-sampling thing!
And are those frequency values you used correct?
Aren't the sampling rate and audio frequency values are 2 different things?
I mean, in 44.1 kHz sampling rate, isn't the max frequency it supports is 20 kHz? The the upper limit of human ears! (in 48, it is 21.8)
I thought it like that... What I thought is the range is divided somewhere in the middle..
(like 10 kHz, probably not) and then the lower part being encoded with 44.1 kHz sampling rate and the higher part is encoded with its half, 22.05 kHz
