I found a problem sample for gapless encoding. Whatever I do, there is an audible click between the tracks. I've analyzed its cause, and found that it comes from edge effects. The termination of the waveform far from zero causes ringing, that manifests itself as an audible click, even when the files are played gapless.

I saw the problem with MP3 and MusePack.

MP3 : Lame 3.90.3 --alt-preset standard ; Foobar2000 disc writer
MPC : Mppenc 1.14 --xlevel ; Mppdec

You can get the file here : http://www.hydrogenaudio.org/forums/index....35&t=18207&st=0

Look at the attached picture to see the problem in the waveform.
