I am not finding mp3direct software very easy to use for non-destructive mp3 editing. I am used to Adobe Audition aka Cool Edit in how easy it is to navigate and chop up files.

Is there any other software that can work with mp3 files to chop and adjust volume without reencoding them after saving?

win32:
MP3DirectCut
musiCutter
MP3Trim
*nix:
cutmp3
other/x-platform:
pcutmp3
mpgedit
PyMP3Cut (Python)

I'm sure there are more, but these seem to be the most popular ones.

Will those programs allow you to increase the volume without re-encoding? I know you can cut an mp3 up without a re-encode, but increasing the volume doesn't seem like something you can do without a re-encode.

MP3DirectCut and MP3Trim can. Not sure about the others.
AFAIK they do it by modifying the global gain field of each MP3 frame.

Wow these are so crude. mp3directcut at least has a visual representation of the audio but I just cannot get the hang of marking my selections.

MP3Gain will let you do that.

Don't forget mp3splt. Granted it's a commandline app, but I've found it to be excellent with splitting up long mp3 and ogg mixes. It can't adjust the volume though. It's supported on most operating systems too.

I use the MP3 editor from Data Becker

http://mp3_players.mp3shopping.com/index.p...5LPRE&Itemid=48

It's $20 and is widely available. It will do all that you ask, and it's insanely simple to use. The editing interface is graphic, similar to Cool Edit et al.

It's in fact impossible. You can't remove the eggs from a cake once it's been baked. wink.gif

Be careful with using mp3trim on gapless tracks which were encoded with lame - unless it was changed recently, you may loose the info which is used by decoders like the one in fb2k to playback files gaplessly. So, mass-trimming your entire music-collection is *not* a good idea.

Nero Wave Editor (Can edit mp3s) for Nero 6 has this facility
(Menu->Enhancement->Declicker)

But not sure about destroying mp3 thing. (Don't understand what u meant)
If u talk about re-enoding then yes it has to reencode after the editing is complete.

Then it's destructive.
If a wav file say is encoded to mp3, then data has been lost to produce that mp3, hence the term "lossy". If that mp3 is decoded to wav again for editing and then re-encoded BACK to mp3 after editing has been completed, the quality of the resulting mp3 file is worse than in it's previous mp3 form: wav -> mp3 -> wav -> mp3 = not good.

Yes but what format do you edit the files in? I've not heard, and indeed cannot find any evidence on their site, that GoldWave can edit mp3s without having to decode them to another format first and then when you've finished encode them back to mp3 (correct me if I'm wrong).

They also seem to have problems with VBR files: see here.

Does any of those splitters maintains the LAME tag on the files, keeping the relevant data in each file created ?

I have tried MP3DirectCut, without luck.

mp3splt does.
I split a LAME 3.97a10 '-V 4 --vbr-new' encoded file and took the first minute from it. This is what foobar shows via the properties info:
CODE
Original file:
lame_version = LAME3.97
lame_profile =
lame_profile_index = 0
enc_delay = 576
enc_padding = 1788
mp3_accurate_length = yes
bitrate = 133
codec = MP3
channels = 2
samplerate = 44100
extrainfo = VBR
mp3_stereo_mode = joint stereo
   --------------------
7984452 samples @ 44100Hz
(mod 588 = 0)

mp3splt file:
lame_version = LAME3.97
lame_profile =
lame_profile_index = 0
enc_delay = 576
enc_padding = 1788
mp3_accurate_length = yes
bitrate = 138
codec = MP3
channels = 2
samplerate = 44100
extrainfo = VBR
mp3_stereo_mode = joint stereo
   --------------------
2644932 samples @ 44100Hz
(rounded samples : 2644824)


The Title, Artist, Album & Comment fields do get changed though.

mp3splt doesn't touch enc_delay/padding appropriately, I guess.
(The outcome most likely won't be something you can play back gaplessly)
I know of no *good* mp3 splitter. (My definition of *good* is something that matches kode54's suggestions which can be found here)
