Converting TS to MP3 (for ABC DiG radio)

[Ext User(Mike)]

I've been recording ABC's DiG radio in DVB TS format.
It seems to be 256kb/s stereo MP3. correct?
Are there any tools to convert it to .mp3 file format
without recoding? Preferably on Linux.

Its 256kbps MPEG-2 audio with a 48kHz sampling rate so I think you'll most
likely need to re-encode it if you want it in MP3.

what tuner are you using?

I'd use a program like cuttermaran or projectX to demux to a .mpa file,
then use BeSweet to convert to mp3 (with option to sample at 44kHz)

NOVA-T, but how does that make any difference? I don't use the
bundled software, which was awful.

Any card will do. Just tune to ABC and extract the right PID.

Which MPEG-2 audio? Do they use mpeg-2 AAC? If so, I guess it will
need recoding.

My decoder (mplayer) just says:
48000 Hz, 2 ch, 16 bit (0x10), ratio: 32000->192000 (256.0 kbit)
Selected audio codec: [mad] afm:libmad (libMAD MPEG layer 1-2-3)

Thanks, but I can already use mplayer to decode, and 'lame' et al,
but I was hoping it was possible to just change the file format
without transcoding.

It is. The audio (on standard Aussie digital TV at least) is in the MPEG
1 Layer 2 format, mp3s are in the MPEG 1 Layer 3 format. With the way
these formats have been designed, any player that can play MPEG 1 Layer
3 can play MPEG 1 Layer 2.

Use a program to extract just the mp2 audio portion of the TS stream (on
the Mac I use MPEG Streamclip, I think ProjectX can do this on the PC).
This file is playable in any mp3 player, if you have any trouble, try
and rename the file produced to end in .mp3.

Great! Thanks Fred. ProjectX is java, so it should run fine on Linux too.
I just need to install the Java SDK, read the docs and try it out.
