These studies reveal that our ear can not perceive frequencies of “weak” at frequencies adjacent “strong”, since they cover (in technical terms, he says: “mask”) the first. The information about the frequencies weaker then, as they would have no perceptible doff ear human, are eliminated from MPEG during compression.

In addition, there are different levels of compression (Layers) used from Free Albanian mp3 download.

The compressions are: the bit rate, about hertz and mono or stereo. A sampling hertz equal, the higher bit rate will have better quality, while the lower bit rate will produce smaller files but lower quality.
