The Principle Of Audio Compression Technology

The Principle Of Audio Compression Technology

In the field of audio compression, there are two compression methods, lossy compression

and lossless compression. Commonly known MP3, WMA, and OGG are called lossy

compression.

Audio signals can be compressed based on audio compression technology. Audio

compression technology refers to the use of appropriate digital signal processing techniques

for the original digital audio signal stream (PCM encoding) to reduce (compress) its code rate

without loss of useful information or negligible loss.

It is called compression coding. It must have a corresponding inverse transform called

decompression or decoding. Audio signals may introduce a large amount of noise and

certain distortion after passing through a codec system.

 

                                            In the field

                                  of audio compression

                                           there are

                              two compression methods

                                     lossy compression

and lossless compression. Commonly known MP3, WMA, and OGG are called lossy

compression.

 

As the name implies, lossy compression reduces the audio sampling frequency and bit rate,

and the output audio file will be smaller than the original file. Another type of audio

compression is called lossless compression, which is the subject matter to be said.

Lossless compression can compress the volume of the audio file less than 100% of all the

data of the original file, and restore the compressed audio file to achieve the same size and

the same code rate as the source file.

 

The lossless compression formats are APE, FLAC, WavPack, LPAC, WMALossless,

AppleLossless, La, OpTImFROG, Shorten, and the common, mainstream lossless

compression formats are APE and FLAC.
