Re: Which has a better MP3 encoder, Foobar2000 or Windows Media Player 12? Reply #25 – 2019-01-03 00:19:14 Undigging the topic, just want to add .02Quote from: Someone2345 on 2017-11-27 04:37:50I guess what was confusing me was how the WMP mp3s actually retained that >20.5kHz data, when that typically is not be expected, when both the WMP mp3 and Foobar2000 mp3 have about the same file size.I think that's not retaining the data, but... clipping. Those frequency "peaks" go up to the Nyquist frequently, which is really unusual in correctly mastered audio. They just look like clipping.Every lossy encoding, including MP3, more or less slightly changes peak level. If in the original audio peaks were close to the full scale, there's high risk that MP3 encoding will clip them! Probably that happened with WMP's encoding.
