Syncing MKV audio (Problem: FPS.)

[PonyoBellanote]

Hello, people! I have a problem, and I'd like some help. I have downloaded the Doctor Who 2005 S1E01 in HD and I want to add the spanish audio, but there's a problem - FPS. How can I sync the audio perfectly?

Here I give you the Media Info of them both archives:

Assuming the frame count of the two sources is the same (which is a big assumption), stretch the Spanish audio to be the same length as the video to which you want to add it. You may be able to use a PAL to NTSC setting in an audio program, or maybe not.

Are you sure you're not discussing illegally downloaded warez? Which can't be done here.

[PonyoBellanote]

The same? There's a big diference, like 23 and 29.. and I don't know what you mean with that, how I do that?

I use MKVMergue to add the audios.

No, no, I ripped the audio from my Doctor Who DVDs, and the blu-ray video is from my friend

I have downloaded the Doctor Who 2005 S1E01 in HD

Make up your mind.

There's a big diference, like 23 and 29.

The DVDs use a PAL source and are at PAL speed. There's only a 2 minute difference between the two. If it were really 23.976fps .vs 29.97fps, the difference would be much greater.

I don't know what you mean with that, how I do that?

If you don't know how to stretch audio and then remux it with a different video, you shouldn't be attempting a project this difficult. Walk before you run.

[PonyoBellanote]

Never too late to learn, can I at least know what software to use? I know to remux, aka add the audio with mkvtoolnix. I only don't know how to stretch the audio to fit.. mostly I just want to sync it.

[manono]

For stretching audio I usually use BeSweet with a GUI or Audacity. Any WAV Editor can stretch audio, though.

Now I need to know what to do, how to scretch.. and sync.. But well
