Steps To Reproduce:
1 Locate an AIFF file that libsndfile can't accept or imports incorrectly such as http://forum.audacityteam.org/download/file.php?id=16340. This file contains IMA4 (IMA ADPCM) compressed audio as recorded and default-saved on an iPad. Dragging the file into Audacity makes libsndfile import the file, which imports as noise because libsndfile can't understand IMA ADPCM in AIFF. Observe that this file opens correctly in QuickTime, iTunes or VLC. 2 Click OK in Preferences (to avoid bug 535) then File > Import > Audio... and select the "QuickTime files" filter. The file cannot be imported because it is greyed out in the file list (and the same goes for AIF, AIFC and MP4 files which are valid QuickTime extensions). 3 The user who has the subject file must now either install FFmpeg or add an Extended Import rule, whereas they should on Mac be able to import the file more simply by choosing the "Quicktime files" filter.
