There are three differences:
1. Different sizes. A song with standard sound quality is about 2-4MB. A song with super high quality is about 5-10MB. A song with lossless sound quality is about 100M.
2. The sound quality is different. Standard sound quality music doesn't sound too rough. High-quality songs sound richer in detail. (For example, the sound of accompaniment instruments) And songs with lossless sound quality sound very clear.
3. Different categories. Standard sound quality and super high sound quality are lossy sound quality. And lossless sound quality is naturally lossless sound quality.
Extended information:
The common lossless formats are ape, wav, and flac, while aac can only be considered high quality. The advantage is that all lossless formats are essentially WAV compression and will be converted back to WAV during playback. Therefore, playing wav directly helps save memory and is smoother. But the disadvantage is that the file is too large, generally more than 30 megabytes. And ape and flac are relatively small.
