Is there a difference between the sound quality of AAC and lossless format?
What a big difference!
Common lossless sound quality is APE, FLAC, etc. AAC does not fall into the category of lossless sound quality.
AAC uses the smallest volume to get the best format that is close to lossless sound quality, but there is still distortion compression after all.
An APE song is a few tens of MB, while AAC is only a few MB.
ACC
Advanced Audio Coding ACC (English: Advanced Audio Coding, AAC), based on MPEG-2 audio coding technology. Co-developed by Fraunhofer IIS, Dolby Laboratories, AT&T, Sony (Sony) and other companies, the goal is to replace the MP3 format. In the year 2000, after the appearance of the MPEG-4 standard, AAC reintegrated its features and added SBR technology and PS technology. To distinguish it from the traditional MPEG-2 AAC, it is also called MPEG-4 AAC.
APE is one of the popular distortion-free compression formats for digital music, compressed by Monkey’s audio software.
Compared with the similar FLAC file format, ape has error checking ability but does not provide error correction function to ensure pure and lossless files; another feature is that the compression rate is about 55%, which is higher than that of FLAC, and the volume is about half of the original CD, for easy storage.
FLAC
FLAC is a well-known free audio compression codec, which is characterized by distortion-free compression. Unlike other distorted compression codes like MP3 and AAC, it will not destroy any original audio data, so it can restore the sound quality of music CDs. It has been supported by many software and hardware audio products since 2012.
Compared with APE, the FLAC format file is a little larger by 2%-3%, but the advantage of FLAC lies in the faster encoding and decoding speed, and the CPU computing power requirement is quite low, and the format is also very fault-tolerant, even if a small piece of music is damaged, and does not affect subsequent music playback.
