GRC, if you are frustrated with Audacity, there are several other software programs that will get the job done much easier. Sony Soundforge (about $250 I think), Wavelab (about $600), or Adobe Audition (about $350). If you google there are $20 or $30 tools for converting formats, including .aif > .wav, but those programs have less features than the ones above. Here is a 21 day free trial of Cool Edit Pro (now called Adobe Audition):

CEP is also handy for determining if a source is lossy or not, and I think you can use this feature even after the free trial has expired. Ask Five which program is the best value.
