5. OGG in high quality request, the damage the world of audio coding is a three-legged Xiang Li, namely, MP3, MPC, OGG. The support of a large number of new technologies, these codes have very good performance, are a group of supporters of their respective owners. The higher bit rates, OGG to show them the quality of which was very commendable, but OGG is also a big disadvantage is the high-frequency metal taste, which is somewhat disappointing.

6. MPC when the bit-rate 200k ~ 250k when you get in, MPC is the best I have come into contact with harmful code, and it is difficult to distinguish it and the number of differences between the original signal, in terms of frequency of a reservation or details of the reservation, as well as the distortion of the signal strength speaking, MPC can be called lossy compression of the king (this compression ratio). MPC is not a panacea, it can not encode 48khz sampling rate of the song, fortunately, such a source of very little tune. Unfortunately, this format is not as popular as mp3 or wma.
