While trying to import an AIFF file, ProTools handed me this message:

Could not complete the Import Audio Command because
Assertion in “FFAudioProcessRequantize.cpp”, line 150

Fortunately, I happened to know in advance that this particular AIFF file was corrupt. (That’s what I get for rolling my own sound files.) The meaning of the message is thus fairly clear. Translation:

That file is corrupt and I refuse to deal with it.
Have a nice day.
