This article is about what lossy compression formats are available in computers. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Lossy compression formats are: 1, mp3 format; 2, AAC format; 3, AAL format; 4, Ogg format; 5, divX format; 6, Xvid format; 7, jpeg format; 8, rm format; 9, rmvb format and so on.

Lossy compression takes advantage of the fact that human beings are insensitive to some frequency components of images or sound waves, allowing the loss of certain information in the compression process; although the original data can not be completely restored, but the impact of the loss on the understanding of the original image is reduced, but in exchange for a much larger compression ratio.

Lossy compression is widely used in voice, image and video data compression.

The common sound, image and video compression are basically lossy.

In multimedia applications, common compression methods are: PCM (Pulse Code Modulation), predictive coding, transform coding, interpolation and extrapolation, statistical coding, vector quantization and subband coding. Hybrid coding is widely used.

What are the common lossy compression formats?

Mp3, AAC, ATRAC3/ATRAC3+ (* .aa3), AAL (ATRACAdvancedLossless), Ogg, divX, Xvid, jpeg, rm, rmvb, wma, wmv and so on are lossy compression.

The lossy data compression method is a compression method that the compressed and decompressed data is different from but very close to the original data. Lossy data compression is also known as destructive compression, that is, the secondary information data is compressed at the expense of some quality to reduce the amount of data and improve the compression ratio. This method is often used in the Internet, especially in the field of streaming media and telephone. It is often referred to as codec in this article. It is the compression method corresponding to lossless data compression. Depending on the design of various formats, lossy data compression will have generationloss: compression and decompression of files will lead to gradual quality degradation.

The defect caused by lossy compression that can be detected by human eyes or ears is called compression distortion (en:compressionartifact).
