Re-encode just the audio

[rinkel]

Hi,
I have a problem with the mp2 sampling rate, my capture card records it with 44,1khz, but for my DVD-player i need 48khz.
So i de-muxed the stream and used besweet to resample. The problem is that the pitch is to high and the audio is played too fast.

Does anyone knows a way of re-sampling the audio (mp2 -> mp2) ??

Thanks

you can decode with madplay,
upsample with ssrc, and
encode with tooLame.

Cool Edit will do any sort of conversions you need without screwing anything else up in the process.
