24.000fps (not 23.976!) audio to 25fps

[Lastman369]

Hi guys, I've got the following problem:

I'd like to speed up the the DTS audio stream of a 24.000fps video file so that I can mux it with a 25fps version of the same movie. Eacto3 can only be used for conversion between 25 and 23.976 fps, so what other tool(s) should I try to solve this problem?

Thanks in advance..

Try AviSynth + NicAudio plugin.

BeSweet can do it.

You're right, but I just can't figure out how to use Besweet. Also, it's a DTS file, not AC3 (sorry I wrote ac3 yesterday) - it might make it more difficult. (I'd like to have an AC3 output file, though)
Could you please explain to me how I can do it? I mean, if you make a (few) screenshot(s) with numbers showing the order of steps, it would help a lot, plus I'd like to know what plugins I need for this conversion. (I guess azidts is what I need, so I've downloaded it from here )

I tested with AC3 before I wrote my reply, just to make sure it would work with audio from a 24fps source. DTS is something else entirely. I know it can be done, because I've messed with DTS before, converting it to AC3, but that was years ago and at that time you needed the DTS filters from WinDVD Platinum. If there are other and easier ways now, I don't know about them and can't help. Sorry.

Uhm... no probs.
.. and what if I make 6 wav files from the 5.1 DTS, or convert it to a 640kpbs 5.1 AC3 (using Eac3to)?
After that, I think I could use Besweet to speed up the audio from 24fps to 25fps. So my question remains the same: how should I set the "24fps to 25fps"? Should I use Besweet GUI or BeLight? Any ideas?

If you really want/need a GUI-based solution, give a try to BeHappy.
I myself prefer the "pure" Avisynth way:

LoadPlugin("Path-To\UNicAudio.dll")
LoadPlugin("Path-To\SoundOut.dll")
UNicAudioSource("Path-To\filename.dts")
ConvertAudioTo16bit()
AssumeSampleRate(50000)
ResampleAudio(48000)
SoundOut() # This command will bring you a convenient pop-up window
# when you open the script in VirtualDub.

I'd say Eac3to is the tool to use for DTS to AC3 these days and it does support 24.000fps to 25.000fps. If you run Eac3to from the command line you will see that the -speedup option supports both 23.976 and 24.000 rates. I usually run it from the command line so if you have any problems using the GUI I'd recommend the command line.

Thank you guys, finally I've managed to solve the problem with the following Eac3to command line:

"H:\Program Files\eac3to 3.17\eac3to.exe" "PATH\input.dts" "PATH\output.ac3" -24.000 -changeTo25.000 -384
