And as for the reverse (24 fps to original 25 fps)?

You mean a 25fps TV source released on Blu-Ray at 23.976 like some BBC stuff, or what?

AssumeFPS("pal_video",sync_audio=true).SSRC(48000)

-or-

AssumeFPS(25,1,sync_audio=true).ResampleAudio(48000)

[-or- etc.]

If the audio was pitch-corrected when it was converted from the original 25fps to "24"fps, you will need to correct it again as part of your conversion back. Unfortunately every pitch correction step introduces unavoidable and unrecoverable artifacts.
