Our ear has a spiral channel which detects various frequencies at various points...
For simplicity, lets assume that the length of the channel is L
Suppose f1 frequency is detected at start of the channel and f2 at the end.
Now, if in a music, f1 comes after f2, within a time interval of L/( speed of sound), then the order of frequencies detected by our ear will be wrong...
But since we dont hear this out of sequence, i think there might be a auto correction or rejection mechanism in our brain.
If the out of sequence frequncies are being rejected by our brain, then we can also do the same to our music files.
Hence we can achieve compression.
We will have to get the time based frequency spectrum of the music,digitize this and pass this through the compressor.
