Improve Audio quality for Mac or IOS (水城百事)

Many people have collected numerous classic MVs but failed to enjoy the music on Apple products with better audio quality, especially the MVs made in a few decades ago and equipped with mp3 format. To cope with this difficulty, you are suggested to convert MP3 to AAC (Advanced Audio Coding), which is treated as a substitute for MP3 to provide better sound quality with the same bit rate. It is a standardized format now used with MPEG4 video. It’s heavily developed because of its compatibility with DRM, for example, FairPlay, Apple’s the most widespread DRM system). At the same bitrate, AAC will generally have better sound quality. And when at higher bitrate, AAC is much smaller in size than MP3. For Apple’s fans, AAC, the increasingly popular format is more than the best audio format choice. In most cases, we need to transfer mp3 to aac for better audio quality.
