3. MP3 comes mp3 can not fail to mention LAME.LAME can be said to MP3 revolutionary history, what, MP3 sound quality is the most controversial issue, and very high-frequency losses, many mp3 encoders coarse coding algorithm not only resulted in high-frequency loss, but also lost a lot of details, like guitar strings rub the feeling is not found in the MP3. in the MP3 is about disappointment, LAME emerged, it supported the principle according to the human ear to analyze the shielding effect of waveform, with the VBR technology that allows sound to reach alarming proportions; its unique model of psychological sound reduction technology ensures the authenticity of the audio CD, with the VBR (dynamic bit-rate) and ABR (average bit rate) parameters, encoding MP3 sound out of pure thick, space broad, bass definition, detail good, sound quality is almost comparable to CD audio, but the file size is very small. Many User in the use LAME to reflect the post is this: immediately remove the hard disk all the MP3 and other encoders, all with Lame start over. Lame provides EXE and DLL, which DLL is a dynamic runtime library as a standard for other programs call. EXE is a Command Line program, the same as the DOS programs work, both independently of each other, unrelated. But we soon be able to find both the quality of coding is not the same, it is because of poor control dll, and adjust the parameters with rich EXE version compared to the effects of MP3 compression out of the rival. But the EXE is a command-line tool, the operation is very troublesome, thanks to WinLAMEr or lameGUIxp the Shell. Learn how to use them as long as the Shell (yes fool type, a look that will be), it can be compressed using LAME far the most exciting out of the MP3. Let me say APS, in the LAME appeared before the, APS is the best MP3 encoder, which uses the Fraunhofer IIS encoding algorithm, more than LAME encoding algorithm used in more advanced, in the under 192k Bitrate, even more than LAME-encoded song to be outstanding, is significantly rich in some of the details, but the APS itself does not support VBR, up to improve when the Bitrate, the sound quality should be worse than the LAME encoding, and most of the friends of the MP3's are usually 128-192K Bitrate, so APS is still there recommended value. In particular, there are many MP3 players do not support VBR and 256K Bitrate more than MP3, LAME will not necessarily fit these friends of the, APS has become a good choice, by its encoded song has never dishonored your expensive PLAYER.
