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.

WavPack -b4x4hc
Opus --cvbr --bitrate 256 --framesize 5
