Arthur,
We have problems playing loops and using the graph with VBR mp3.
For example if we see the graph of an mp3 recorded in VBR and then convert to CBR then graph is different and so if we ask to loop precisely between 10.00 sec to 11:26 sec for example it wont be the same before and after the conversion if VBR change between 10.00 and 11.26.
So is it also possible that in case of VBR that the position between you and bass gets different, and loops play badly because graph don't match bass playback?
Thank You
