Multiple MP3's to one .MP2

[MattO]

I can't get to my system at the moment to try it, so I thought I'd ask here:
Does anyone know whether Besweet can convert multiple MP3 files, (in .LST form maybe), into One .MP2 file?

thanks for any info, and any commandline examples.

Haven't tried it, but should be no problem. Make a .lst file of the mp3's ( easy way to do this - open a command window in the directory with the mp3's and type 'dir /b *.mp3 > besweet.lst' ) and use a commandline something like

BeSweet -core ( -input "path\besweet.lst" -output "audio.mp2" ) -2lame ( your options here )

[MattO]

Thanks KpeX, that does work but ...

When playing back the .MP2 file there is a strange squeaky noise in the background.
Does anyone know what could cause this?
Has anyone experienced this?

By the way the .MP3's I am using were created with EAC 0.9b4 using Lame.exe (19 july 2002) with the default commandline:
%l--alt-preset 128%l%h--alt-preset standard%h %s %d

With EAC's bitrate set at 192 (not sure if this affects anything).

Can Besweet handle vbr MP3 input?

thanks

Hmm interesting......so the squeaking isn't present in the mp3's? Try posting a logfile if possible. If you encoded from EAC....why not just encode that to .mp2? rip the wav's with EAC and encode that with BeSweet.

[MattO]

No, the squeaking is not in the original .MP3 files.

I can't produce a logfile at the moment, I am not at my home system.

I am using the latest beta version of Besweet (b19).

I didn't want to use EAC to create the .MP2 files as my whole intention was to put multiple songs into one file. Plus, I have loads of .MP3 files which I want to use.

My ultimate aim is to have multiple .MP2 files, each a seperate album, burnt to a DVDR with DVDMaestro (the video can be a still picture), selectable via a custom menu, thus enabling me to put approximately 750 songs on 1 disk. Theoretically it should work, and I want to try it ;)

Do you know if Besweet can handle VBR .MP3 files?

Also, if I'm not mistakened the pitch of the resulting .MP2 file has changed, audio has speeded up slightly.

Can anyone, possibly, try what I am doing and post their findings? please ;)

My commandline, from memory (as I am not at my home system) is:

besweet -core( -input "mp3.lst" -output "album.mp2") -shibatch( --rate 48000) -toolame( -b 128 -m s -e )

Is the rate conversion causing the problem? But this is necessary because of the DVD destination.

I have noticed this problem from time to time when transcoding from mp3 to mp2. I solved it by transcoding first to a uncompressed wave, the a mp2. Maybe others have a better solution.

[KpeX]

MattO, I've done some testing and I believe this is a .lst file handling problem. When transcoding from VBR mp3 to mp2 with a .lst file, the tempo definitely increases no matter what options I change. Not only that, but the tempo speeds up even when the lst file contains .wav files, and even if shibatch is not used! I'm not sure there's a good solution to this with BeSweet at the moment, but I don't think it's anything you're doing wrong. I may be wrong but I don't think BeSweet handles .lst > mp2 very well at the moment. Here's some logfiles:

First, transcoding a list of .wav files to mp2:

As you can see, it's displaying a strange actual average bitrate, and showing more .dll's in use than should be. Neither of these behaviors occur without a .lst file, also the tempo is fine when transcoding a single file as well.

Thanks for your testing :)

Hopefully DSPguru will read this and confirm, or correct us, as to whether this is a bug or not.
