I have some audio capture from Freeview transmissions in the UK (DVB)

I can demux the Audio out using Project X, but that gives me MP2.

My goal is to generate an MP3, for better software/equipment compatibility. I (obviously... rolleyes.gif ) do not wish to incur any degradation in the conversion.

I note the existence of Jpegtran, a set of routines that perform limited manipulation of JPEG image without performing a decode-recode pair.

I wish a similar transform, from mp2 to mp3 (if it is possible).

Given the existence of mp3repacker, a VERY rough (but lossless) mp2 to mp3 implementation would serve, since the output mp3 could be retrospectively tidied.

I dont think it's possible. MP2 encodes audio in the time domain, MP3 does it frequency domain so although they have the same MPEG file format the two codecs are different.
