Well i changed a few lines to make it convert linearPCM to compressed,
i think i have sorted it out by setting
kAppleLosslessFormatFlag_16BitSourceData
on the dest format before passing the asbs to
AudioFormatGetProperty(kAudioFormatProperty_FormatInfo...

the offline example will only generate linear pcm, so I don't know
what you are changing here, but you aren't getting what you think
you are

I tried the AQOfflineRenderTest for converting from 16 bit PCM 2
channels 44100 to AppleLossless,
the original file size is 1.1MB but the Lossless is is 1.5MB ?
i only changed the dstFormat.mFormatID = kAudioFormatAppleLossless,
is also tried the kAppleLosslessFormatFlag_16BitSourceData on the
captureFormat
but it didn't help.
is there any settings ex. quality for the lossless format ?
PS I started out real happy by converting to kAudioFormatMPEG4AAC
on the simulator but it did not work on the device.
is there a reason for not having offline non realtime mpeg-4 aac
encoding ?
