ExtAudioFile questions

Will the ExtAudioFile / AudioConverter API convert between stream formats with different numbers of channels? In other words, if I ExtAudioFileOpen() a file, and then set the kExtAudioFileProperty_ClientDataFormat property with an AudioStreamBasicDescription.mChannelsPerFrame value different than that in the kExtAudioFileProperty_FileDataFormat property's value, will then calling ExtAudioFileRead() successfully convert up to more channels or down to fewer channels in the output buffers, or does this not work?

Also, I remember a while back there being a series of emails from Brian Whitman about the AudioFile API crashing when encountering certain malformed (but common) AIFF files. Was this ever fixed? If so, in which version of Mac OS X?

thanks,
Sophia
