Lossless music is a type of music file playback format. Music file playback formats are divided into two types: lossy compression and lossless compression. However, due to data loss during audio digitization, it is actually impossible to achieve true losslessness now. APE is one of the popular digital music file formats.
APE is a lossless compression audio technology, which means that after you compress the audio data files read from the audio CD into APE format, you can also restore the APE format files, and The restored audio file is exactly the same as before compression without any loss. ?
The commonly seen MP3, WMA, and OGG are called lossy compression. As the name suggests, 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 can compress the size of the audio file to a smaller size while retaining 100% of all the data of the original file. After restoring the compressed audio file, it can be the same as the source file. size and the same code rate. Lossless compression formats include APE, FLAC, WavPack, LPAC, WMALossless, AppleLossless, TTA, Tak, TAC, La, OptimFROG, and Shorten. The common and mainstream lossless compression formats currently include APE, FLAC, TTA, and TAK. WAV general CD can capture music in this format.
However, because it is large in size and is uncompressed original audio, it can generally be compressed and converted into smaller FLAC or APE. Note: wav is still a lossless format, while the latter two are lossless compression formats. FLAC is the abbreviation of Free Lossless Audio Codec, which can be interpreted as lossless audio compression coding in Chinese. FLAC is a well-known set of free audio compression codes, which is characterized by lossless compression. Unlike other lossy compression codes such as MP3 and AAC, it does not destroy any original audio information, so it can restore the sound quality of music CDs. It has been supported by many software and hardware audio products since 2012.
