Analyze All kinds of Music Format Part 2
Music CD
CD, a CD that can play sound files in about 74 minutes, the Windows system comes with a CD player, In addition most of the sound card software that came with the CD playback, nikon en-4 and even some of the CD-ROM from the computer, as long as access through the power supply can be used as a stand-alone CD player.
WMA of unlimited potential.
Microsoft to develop their own network multimedia service platform on the main push of the ASF (Audio Steaming the format), which is an open standard to support the transmission of data in a variety of networks and protocols. It supports audio, video and other multimedia types. WMA is the abbreviation of Windows Media Audio, which is equivalent to the ASF file that contains only audio. WMA files in the compression ratio up to 1:18, 80kbps, 44kHz mode is basically the same and VQF. And compression rate than MP3 doubling. Therefore, it should be more competitive than VQF.
Free music format Vorbis
In order to prevent the MP3 music companies charge patent fees rise GMGI the iCast company of programmers to develop a new free music format Vorbis, its sound quality is comparable, np-qm71d or even superior to MP3 and MP3. And will be released through the network, you can free download and do not have to worry about will involve the infringement. MP3 on the Internet has been very popular, Microsoft’s Windows Media technology also began to spread, Vorbis, the outlook is not optimistic.
Nondestructive sound APE
APE is a lossless compressed audio format. Large WAV audio files via the Monkey'’ s, Audio software “downsizing” compression for the APE. Very time it is used as a network audio file transfer, because more than half of the APE file size is compressed than WAV source file, you can save transmission time. More importantly, can be done by the Monkey'’ s, Audio unzipped to restore WAV files and compressed before the source file is exactly the same. Therefore, BG-E3 APE known as “lossless audio compression format, the Monkey'’ s Audio known as” lossless audio compression software. Using WinZip or WinRAR such professional data compression software to compress audio files, compression of APE audio files can be played. Monkey'’ s, Audio to Winamp to install a the in_APE.dll “plug-ins, so that Winamp also has the ability to play APE files In short, the APE is now one of the best lossless compression audio format
Other audio formats
Of AIF / AIFF: Apple to develop a sound file formats, support the MAC platform, supports 16-bit 44.1kHz stereo.
AU: AU Sun’s compressed sound file format only supports 8 voice is the sound file format commonly used to interconnect online, created mostly by the SUN workstation.
The CDA: CD track files.
The CMF: CREATIVE company developed a similar MIDI sound files.
DSP: Digital Signal Processing (digital signal processing) referred to. Improve the signal processing method, the sound quality will be greatly improved, songs will be more melodious np-bn1 charger.
S3U: MP3 player file list
RMI: the MIDI instrument sequence
Lossy compression:
AAC: high bit rate, sound quality is second only to the MPC, very good appearance in high bit rate and low bit rate. Is the encoding speed is too slow!
MPC: low bit rate performance in general, less than MP3 and OGG Mp3Pro encoding, high bit rate, the best sound quality, encoding speed!
OGG,: at low bit rates the best sound quality, high bit rate is also good. Encoded at a slower pace.
MP3 (MP3Pro): in the low bit-rate sound nikon MB-D10 quality inferior to OGG, and other aspects of the same MP3
WMA: high and low bit rate, in general, does not support VBR, up to 192Kbit / s
Lossless compression:
FLAC: Compression rates in the four worst, the coding speed is good, platform support very well.
PAC: the slower the encoding speed, compression rate ranked third, platform support.
APE: the fastest encoding speed, the best compression ratio, bp-535 platform support in general.
The WV: encoding speed is very fast, the compression ratio ranked second in the four kinds of support for the Windows platform only
