No, it can't. To see a list of files that can be handled, build the
afconvert example and run it with no arguments. You'll see something
like this:
Usage:
afconvert [option...] input_file [output_file]
Options: (may appear before or after arguments)
{ -f | --file } file_format:
'adts' = AAC ADTS (.aac, .adts)
data_formats: 'aac '
'ac-3' = AC3 (.ac3)
data_formats: 'ac-3'
'AIFC' = AIFC (.aif, .aiff, .aifc)
data_formats: BEI8 BEI16 BEI24 BEI32 BEF32
BEF64 'ulaw' 'alaw' 'MAC3' 'MAC6'
'ima4'
'QDMC' 'QDM2' 'Qclp' 'agsm'
'AIFF' = AIFF (.aif, .aiff)
data_formats: BEI8 BEI16 BEI24 BEI32
'caff' = Apple CAF File (.caf)
data_formats: '.mp3' 'MAC3' 'MAC6' 'QDM2' 'QDMC'
'Qclp' 'Qclq' 'aac ' 'agsm' 'alac'
'alaw'
'drms' 'dvca' 'dvi ' 'ima4' 'lpc '
BEI8
BEI16 BEI24 BEI32 BEF32 BEF64 LEI16
LEI24 LEI32 LEF32 LEF64 'ms\x00
\x02' 'ms\x00\x11'
'ms\x001' 'ms\x00U' 'samr' 'ulaw'
'vdva'
'MPG3' = MPEG Layer 3 (.mp3, .mpeg)
data_formats: '.mp3'
'mp4f' = MPEG4 Audio (.mp4)
data_formats: 'aac '
'm4af' = MPEG4 Audio (.m4a)
data_formats: 'aac ' 'alac'
'NeXT' = NeXT/Sun (.snd, .au)
data_formats: BEI8 BEI16 BEI24 BEI32 BEF32
BEF64 'ulaw'
'Sd2f' = Sound Designer II (.sd2)
data_formats: BEI8 BEI16 BEI24 BEI32
'WAVE' = WAVE (.wav)
data_formats: LEUI8 LEI16 LEI24 LEI32 LEF32
LEF64 'ulaw' 'alaw'
... etc ...
As for solving your problem, I think you'll need to use VLC if it
supports format conversion or some other 3rd party tool. It sounds
like you have the QuickTime MPEG-2 support product installed but I'm
not sure if that includes support for format conversion of the
MPEG-2, as you noted. Is your MPEG-2 component up-to-date?

I am having problems playing mp2 audio files generated from a HD

This mp2 file can be played in VLC, quicktime (but unable to export
using quicktime functions/app for some reason). I need to be able
to change it into a wav file or something more usable as I need to
edit/join it. Can the core audio SDK handle mp2?
Thanks
