I wrote a little drag & drop applescript to convert to AIFF 16bit--copy this into Script Editor and save as Application, then drop files onto it. It uses Quicktime Player (you don't have to have the Pro version). It will convert any QT-compatible format (including 32-bit AIFFs) to 16-bit AIFF. The converted copies will be on the Desktop.this is actually quite useful... is there a way to do it to 24-bit? http://bhobrainey.net
