MP3, with the formal name of "MPEG Audio Layer 3", is a compression standard defined by
MPEG, a joint executing agency under ISO (Organization for Standardization) and IEC. An MP3
file contains compressed audio data. MP3 encoding can compress audio data at an extremely
high ratio, thus reducing the music file's size to one tenth of the original size. At the same time,
the sound quality remains close to that of CD. MP3 achieves such a high compression rate by
removing sounds that cannot be heard by humans or that are drowned by other sounds.
WMA, or "Windows Media™ Audio", is compressed audio data. WMA is similar to MP3 audio
data.
WAV is an audio file format developed by Microsoft. It conforms to the file specifications of
RIFF (Resource Interchange File Format) and is used to save audio information and resources
on the Windows platform. It is widely supported by the Windows platform and its applications.
This format also supports several compression algorithms such as MSADPCM and CCITT A
LAW, and supports multiple audio digital sampling frequencies and sound channels. A WAV
file of standard format has the same 44.1 kHz sampling frequency and 16 digitalizing bits as CD
format, and thus have nearly the same sound quality as CD! It is the audio format that is the
closest to lossless music, and therefore the file size is large.
FLAC can be explained as lossless audio compression and coding. FLAC is a well-known free
audio compression and coding technology characterized by lossless compression. Different from
lossy compression and coding such as MP3 and AAC, it will not destroy any original audio
information.
APE is one of the popular lossless compression formats for digital audio. Different from lossy
compression formats such as MP3 that removes data (to which the human ear is not sensitive)
irreversibly to reduce the size of the original file, lossless compression formats such as APE
reduce the file size by a more refined recording method, so that the restored data is the same as
the original file. The integrity of the file is ensured.
