App to edit (cut) an mp3?


Hello people, does anyone know of an application that can cut the ragged ends of mp3 tracks? It's a job that's easy to do when I save the music to minidisc as it has a built in tool for dividing songs. But these days I tend to play the music direct from the computer with xmms, just using the minidisc player as a digital to analog converter. The way music goes together matters to me and some live songs have some ropey endings with talking and stuff that I'd like to chop off. I tried a program called Audacity and it was a challenge to get it to compile and use Alsa but I got there and it will play the music but none of the editing functions work, all the buttons are greyed out so it's no use. Can anyone recommend something that works?

Odd, Audacity seems to edit mp3's fine for me. Have you tried exporting the mp3 out to wav and then editing that through Audacity, and then re-encoding?

You need liblame.so for Audacity to work with mp3's. You may try installing lame and just creating the symlink Audacity asks for. Or you can use ReZound (which also needs some sort of mpeg decoder to get the wave form out of the file).

I have Lame installed and it works fine, I use it to convert .wav files to .mp3's it's Audacity that isn't working for me. It won't edit .wav files either, by the way. It'll play them but Xmms does that better.

Do the files have the 'w' attribute? (dumb question, I konw, but you maybe trying to edit a read-only file!). Will Audacity let you record sounds, then edit those?

I understand how permissions work. Audacity works if I drag the mouse over a section and choose Export as mp3 from the edit menu but it's very crude, hit and miss. There's no way to hear what the join between the tracks will sound like. In music, rhythm is very important. The ear is sensitive to tiny delays. I've be using minidiscs for ten years and with them you can edit to fractions of a second and hear the differences as you're working. I've just become used to it and it seems strange to me that computers haven't caught up yet. Minidisc's on it's way out anyway, being replaced by mp3 players.
So, anyway, to get back to the topic, is Audacity all there is? Well I guess I'll just have to live with it. Thankyou for your time.

I think Audacity can do what you want. The reason the buttons are greyed out is because you haven't selected the track yet. I'm working from memory here, but after you load the track, you will have to split it into stereo. Click whichever track you want to work on, and then the buttons will be active. In other words, they will remain greyed out until you have selected the specific sound file you want to edit. If you haven't already done so, walk through the Audacity tutorial, and it will illustrate how to perform basic editing functions. -- J.W.

As far as I know, Audacity requires you to convert mp3 to wav and back again, which means you loose some quality, and it is also rather slow for large files.

There is a free tool called mprDirectCut for Windows that works fine and doesn't convert mp3s to wav first. There is also a free program called mp3cut for Linux, but it doesn't seem to work as well. I use mp3DirectCut to edit radio programs recorded via DVB card in mp2 format. The Linux mp2cut program doesn't support that format though ;-(

With all the mp3s floating around the web, why aren't there any Linux programs for editing them without converting to wav first?

Hey I found the app to do the job (thanks to RolledOat in another thread) Rezound http://rezound.sourceforge.net/ is the one for me.

It does indeed rock. To me it is now `The Sound Gimp'. A most excellent application.

Word!

I think that if you're into repairing sound from say old tapes or vynil disks, the perfect complement to ReZound is undoubtfully gwc (Gnome Wave Cleaner), another excellent application.

I was looking for a similar program so I just tried Rezound. It no longer appears to handle mp3.

Is this the case or do I have a problem?

You need lame installed to use mp3, it seems:
Code:
- File Formats:
	- Native ReZound
	- WAVE				(libaudiofile)
	- AIFF/AIFF-C			(libaudiofile)
	- NeXT/Sun 			(libaudiofile)
	- Berkeley/IRCAM/CARL		(libaudiofile)
	- raw				(libaudiofile)
	- Ogg Vorbis			(libogg and libvorbis)
	- MPEG Layer-3,2,1		(lame)
	- FLAC (preliminary)		(libFLAC LIBFLAC++)
	- MIDI Sample Dump Standard	(/dev/midi)
Also, don't expect answers from the original posters as this thread is over 4 years old
