pcutmp3 tool, properly/perfect cut mp3 Options

[greynol]

CUE sheets are for indexing CDs and CDs are 44.1kHz, not 48kHz.

[djphatic]

I fixed mp3 using this tool, but I see the same error again:

C:\>java -jar pcutmp3.jar --cue "ASOT.cue" "ASOTfix.mp3"

I have the same error. I have ran the mp3 through mp3brfix and no errors are found

Any suggestions?

[djphatic]

Managed to get things working.

Is there anyway to have a batch file which puts the cut files into a new folder which is has the Album Name?

My current batch looks like this (which I copied from this thread)

CODE

@echo off
title pcutmp3
cd /d "C:\pcutmp3\"
java -jar pcutmp3.jar --cue %1 --dir "%~dp1\
pause
exit

[Jojo]

I'm on Win 7 64 bit, and get the following error

C:\>java -jar pcutmp3.jar
'java' is not recognized as an internal or external command,
operable program or batch file.

using

CODE

pcutmp3.jar --cue 1.cue

cuts the files, but I don't get any output info.

I also tried two versions hosted on the website and they don't work at all, I get the same error as the poster above.

Any idea?

Hmmm, are you sure you have Java installed?

The error you get is that the Windows command prompt doesn't find any executable named 'java'.

Or "c:\Program Files (x86)\Java\jre6\bin" if you have 32-bit JRE installed.

Is there any update to jid3 which will write more than the usual artist, title, album tags?

It would be great to get the discnumber and year/date tags and whatever else is contained in the original mp3 to be written to the split tracks also.

[J0sHi]

I cant believe this program is dieing, Its the only tool on the web that i could find that cuts LAME encoded mp3s accuratly and gaplessly.
Its a hidden gem really, people would pay for this. I would it if it had a gui and the bugs were worked out.

Simply because its one of a kind. I cant believe its left half complete.

madness.

Considering by the looks of it, its been around years.
I only found this last month.

It's not dying. It works fine. The source code is available if anyone wants to continue it or alter it. The reality is that it works so well that no changes have been needed.

Something is wrong with new beta version (notice totally wrong filesize and cuts in Beta version):

Can some developer comment this?

Did you ever figure this one out?

I seem to be having a similar issue though this is with 0.97.1 and 0.98 BETA. The cuesheet loads and plays fine in foobar but when I split all the track lengths are completely different and wrong.

[djphatic]

It appears the issue is related to 48hz encoded livesets I have been trying to split, which the progam does not support correctly.

[Ryo94]

HI, I'm using the pcutmp3 095b that is embedded in gui 0.3. Is there any version of the gui that comes with pcutmp3 0.98? thanks in advance.

[neovibe]

Win+Break -> Advanced system settings -> Environment Variables -> edit PATH variable: add

CODE

c:\Program Files\Java\jre6\bin

to it

Or "c:\Program Files (x86)\Java\jre6\bin" if you have 32-bit JRE installed.

thanks for this one!

[AdamBast]

ohai

1st: thanks for this tool

2nd:
no matter what i cut, the mp3 tags don't show up correctly in jetaudio.
other plyayers tested (just to view the tags):
tcpmp -> same problem
wmp 11 -> same



left is (white background) what totalcommander shows, the normal file names
right is (gray background) what the players shows

i think it's maybe some unicode problem, specifically jid3.jar-related, but i'm not sure

thanks in advance for any help

---------------------------

+question: does pcutmp3 append gaps by default?
if not, how can i make it so?

Hello.
I recently had to use pcutmp3. This is a wonderful program, seems to be the only one on the web to achieve true gapeless cuting. Unfortunately, the mp3 was 48Khz and I bumped into the same bug some of you entountered.

I made a quick fix to pcutmp3, thanks for putting in on google code.

Anyway, here is my patch: (I also corrected the leading 0 in track number)

I did NOT change the version number, only the main maintener should do it, and release another compiled jar.

I would be glad SebastianG or senab can review the patch and commit it to the code.
I only tested it with a 99 track 44.1 Khz mp3 and 99 track 48 Khz mp3. (Did not test other layers).

Hope it can be useful.

I ran into a 48khz file today and came here to ask about it. Looks like i'm not alone with this problem, and it looks like people are trying to resolve the problem (thanks megar!).

I have no knowledge on how to compile jar files though, so i'll second megar's request that the code be checked and hopefully accepted and released.
Thanks.

I uploaded a precompiled pcutmp3.jar here : https://niki.atomas.com/files/pcutmp3/
It includes the source code changes from the 0.98beta release.

Changelog:
- [fix] support for 48Khz mp3
- [fix] fix the leading 0 in %n scheme
- [fix] don't print exception if no file given
- [new feature] --split-in N : to cut a mp3 in N equal parts
- [new feature] --split-every N : to cut a mp3 every N seconds.
- [change] jid3.jar is now bundled

Please do not spread it, I am waiting for the answer from the original authors.

Please report if it works.........

Thanks, megar

The split points are all in the right places now, but there seems to be an issue with the original file's Gapless information.
My original had no delay at the beginning of the track, but it looks like a 576 sample delay (LAME's default) is added after a split.

So the file is split perfectly, but the length is changed. I'm going to experiment a bit and see what else i can find.

[megar]

I think that's the correct behaviour. pcutmp3 add a mp3 frame as the start of the 2nd mp3 with silence information. It is used to fill the bit reservoir. See http://www.hydrogenaudio.org/forums/index....st&p=315678
It is also explained in the first post of the topic.

If foobar can play the song without any gap, it is OK, the first frame pcutmp3 create is compensated by a high encoder_delay, but the shown total frames of the songs will be greater.

The first song should not be altered, though.

I may add a --rejoin option to rebuilt the largemp3 file, but that's another story.

I am in need of a tool that can split mp3 files using cue sheets on Mac so I came across pcutmp3.

Megar, I tried your version and it worked just fine. However, gapless playback is not 100% accurate. When I import the mp3 files I created with pcutmp3 into iTunes, some of them sound gapless and others have a slight hick-up. Tiny but it's there and noticeable for techno / house mixes.

Is there anything I can do to resolve this problem? I already tried enabling the gapless playback setting for each file in iTunes without success.

[megar]

Do the generated mp3s play completely gapless on Foobar ?

I don't have iThunes, but I found these two resources:
http://www.sturmnet.org/blog/2008/11/06/ma...ayback-nonsense
http://manishbansal.wordpress.com/2010/10/...lems-in-itunes/

The second one gives a cookbook to fix mp3 stream / vbr header. It seems iThunes doesn't read the lame tags but try to guess values other way (don't know which way).

You may try the cookbook, maybe it will be successful.

I only have Macs so foobar isn't an option...

Anyway if it's iTunes not following the standards it wouldn't surprise me. I tried several apps including your build of pcutmp3 but with each try, iTunes does not seem to be handling the gapless playback like it should. The results differ and pcutmp3 does seem to be doing the best job but still some tracks have a hick-up.

iTunes works great for me on Mac but I guess I should keep mix cd's a single file like I download them, too bad for Last.fm

[megar]

Well, I can try to help. If you send me two or three mp3 cutted bu pcutmp3, I can try to rebuild mp3 stream / fix vbr header, then send them back to you. So we will have a clue. In that case, it would means that pcutmp3 does not produce completely good mp3. But I think it's unlikely, because it re-write a (I think) correct mp3 vbr header. You can upload the files on a public upload site and send me the link (by Private Message).

Since I got no answer from the author, I decided to fork the project on my Bitbucket account.
It is here : https://bitbucket.org/gbouthenot/pcutmp3/
I do not claim being the original author. I would remove it if the authors ask me to. It's New BSD Licence, so it should be legal, though.

The webpage provides a download link for the compiled jar (Megar Build 3), So I will remove Build 2 from here.
