Roland, I think you're using SVN version, and in SVN we have new feature called WSOLA which is supposed to improve quality. It seems that the algorithm probably is too heavy for PDA's so it produces the Star Wars effect (on different occasion I might call this a feature ;-) ). Samer, I think you're using 0.8 release version, hence the crash. You can try with upgrading to the latest version and see if you still have the crash (you may, of course, get the Star Wars effect as what Roland describes :) ). Let me create a configuration to disable WSOLA for PDA's and get back to you soon. Cheers Benny > Regards >
