how to split audio to separate channel ???

I have the following audio stream test_stereo.mp2 and I want to split to test_mono_left_channel.mp2 test_mono_right_channel.mp2 Is there any software which can do that ???

1. convert it to stereo .wav file in winamp (options/output/diskwrite) 2. load in a wave editor such as WaveLab, save the left and right channel as mono wave file separately (save special/save left...) 3. encode the mono .wav file as mono mp2.

Do I have to reconvert ??? 

Is there any way to split the channel without reconvert, I thinking about if is possible to demultiplex the left and right channel without reconverting to wave ??? I want to run it in midnight. Is there any software can do the job in batch mode ??? It this possible or have anyone do it in BeSweet ???

i don't know of any tool who offers this. although, if your source mp2 is encoded as 'dual channel' this might be possible to 'demux' the mp2 into two mono mp2s. (loselessy! without decoding+encoding). as for waves, BeSplit can be used to demux N mono waves out of a N-channles wave file. (that's also includes N=2 ;)).

you'd think if its not joint stereo this should be possible.. :\

joint stereo - impossible.

@RadicalEd It it not necessary to repeat well-know facts and you've posted it yourself. Important is how to split the mp2 dual channel to 2 mono channel directly. Post you anwer here if you know what DSPguru has no answer of my inquiry jet, but claimed it.

DSPguru is the one who repeated the fact ;P

amv.org pretty much = short useless messages, yes, I've been severely tainted by spam ever since I migrated over there 4 months ago. Anyway Phade cleaned the place out last week and it's boring now since the off topic forum is auto-pruned every 3 days :/ they killed spam. [end long useless message] ;) ok, thats enough :D
