128kmp3 and 192kogg are very different in sound quality, 192kogg is much better.

192k is a watershed. Below 192K, the sound quality is relatively damaged, especially the high-frequency part greater than 16Khz will be cut off. To put it simply, for MP3s above 192k, ordinary household equipment can no longer hear the difference in sound quality from CDs, except for Golden Ears and Hifi equipment. Of course, this data is not 100% reliable. Some people on the Internet shared fake mp3 files with a resolution of 192K or more. In fact, they hard-coded low-bitrate music to high-bitrate music through software, but the sound quality will not be improved. There are also windows media player compressions. MP3 is definitely weird. No matter how high the bit rate is when compressed, there will be a neat cut around 16K. So if you like to compress MP3 by yourself, definitely don't use Windows Media Player.
