I recall this being brought up before but I cannot find the thread using the search.
I have an album with 15 tracks, 14 are 80kb 22kHz MP3s and one is a 128kb 44kHz MP3. I choose the tracks and select Replaygain->Scan selection as album
It scans fine until the track at 44kHz, at the end of scanning that track it says "An error occured while processing files".
I know this is an odd situation (albums should be all encoded at the same rate) but surely it shouldn't stop the application of replaygain?
Oh and if I scan only per track, it doesn't complain so it's something in the calculation of the album replaygain parameters that is not coping.
