I have also just experienced the "chipmunk" effect on several of my mp3 files, and I am certain they were fine in the past. Since this now makes 3 of us it possibly could be something in a recent build, I just tried updating and rebooting, to no avail. I have found this on on least 4 different files, don't know how many others might be affected. So far these files don't seem to be related in any way (time frame downloaded, same artist, etc) and are totally random. These files are not ripped and were fine when I downloaded them and up until today. I did recently do replay gain analysis on my whole library and did have several files that errored out. I subsequently re-encoded them in tools (changed a slight property and let it decode and re-encode) and them analyzed them with no problem. I don't know if any of these are the chipmunked files, but it is the only thing a can think of that has recently changed on my system or in my library. I have other computers networked and have tried these songs with media player and get the same effect, so it seems to be the file and not the player. Any help or suggestions would be welcomed since I have no idea how extensive this problem may be in my library.
