Tag: which is the best format for audio songs

Which format has the best sound quality for music?

PCM, the highest level in audio files, is the ancestor of all digital audio (not including analog), with the highest fidelity and high volume.

Common formats include pcm and cda, which are primarily used to burn records as CD files. CD is not a format, it is a standard, please refer to the official red book published by SONY (Sony) for details. It could be on a common CD-ROM, which was later modified) and cannot be saved as format.
Therefore, it must be said that PCM format has the best sound quality, but its volume is extremely large, so it generally uses WAV as the original file to save audio files, the quality is also quite high, the loss is almost quite small, but the volume is relatively large. This is a format developed and illustrated by Microsoft, which is suitable for Windows operating systems and can also be used on the latest MAC systems. Extension: .wav
is the original audio format dedicated to the MAC system, it is AIFF, the extension is Aiff, which was independently developed by Apple and is very common on Mac. That said, this is the best format (except PCM) on a Mac.
On Unix and Java platforms (which mostly refer to SUN platforms), the corresponding format is AU and the extension is au. It is currently the standard audio format under Unix and Java.
The above formats are all original file formats, which are usually huge in size. In order to facilitate transmission on computers, people have developed compression formats. Compression is divided into lossy compression and lossless compression. Obviously, lossy compression has a higher compression rate, but it requires The problem to be solved is how to solve the sound quality problem. The usual practice is to sacrifice the part that the human ear cannot hear, but the human ear is very different, so it is difficult to care for all people. Among the song formats, the best ones are flac (lossless, flac extension), Monkey’s Audio (lossless, ape extension), DTS (multichannel, mainly used with DVD, dtc/wav extension), AC3 (released by Dolby, multichannel surround , realistic sense of presence, extension ac3), AAC (loaded, good sound quality, extension Aac or mp4), WMV (this is also a video format, an improved version of wma and asf, quality is comparable High, extension wmv), as well as MusePack (mpc extension, completely free) and MP3Pro (mp3 extension) are also quite good, these formats are quite high in sound quality, even for users who require not bad sound. Also, the most popular formats are mp3 and ogg, as well as SONY’s special ATRAC/ATRAC3 format, which is dedicated to MD. These effects are also good and are more common on the Internet, but the effect is obviously not as good as the formats mentioned above.
As for rm and wma, because the compression is too high, the sound quality is really unflattering, especially those that circulate on the Internet, which are lost and cannot be lost anymore, so it is highly discouraged.
