In lossy compression formats, like mp3, aac, aac+, ogg, etc., everyone always tries a new format and listens extremely closely for audible quality problems. The problem here is how you listen to music normally and how you analyze music in detail.Everyone listens to music for enjoyment, not paying much attention to quality. But when it comes to thinking about an encoding format, everyone immediately becomes an audiophile and won’t let go of their high bit rate files.
