MP3DirectCut does this - http://mpesch3.de1.cc/mp3dc.htmlI tried using it, but not sure how it does what i am looking for.-Ampa (December 02, 2009, 11:13 PM)
I had used audacity (http://audacity.sourceforge.net/) in the past but I don't know if has the feature you seek....and it pretty much sucks :( - pretty sad that this is the opensores audio editor "flagship".
I am mentioning it because it is FOSS 8)-housetier (December 03, 2009, 06:33 PM)
P.S. In my testing I found that leaving a bit more silence than I expected near the splits seemed to work better -- at least in one case, I got the sense that there was some lost audio.Could easily be the case, since mp3directCut avoids re-encoding to MP3 - that does mean it can't work on millisecond intervals, but has to work at the MP3 frame size instead.-ewemoa (April 12, 2011, 08:38 PM)

Edit positions in the file can only be placed at the start of an MP3 frame (of which there are typically about 38 per second).
...
The documentation warns that navigating a song does not, in all cases, land on the start of an MP3 frame. The documentation does not guarantee correct results in all cases.

The reason I am posting about Code-it right now is, that I have realized that these weird low priced applications right now are offered at an even more ridiculous low price. Read what you get for $10, it is of another planet:Wave MP3 Editor PRO tools...

The following is a list of most all the specialized tools you get with PRO: some are "one trick ponies" and others have complex functions...

I miss the "Append all/selection to..." save option!
It's not longer necessarry since mp3DirectCut has virtual Cut, Copy & Paste. Open a second instance of the program where you copy the part you want to append. Then paste the selection the end of the other track. "Save all..." creates the combined file. You can also paste multiple selections. Before saving, the program does not copy real audio data but only references. So you must keep every file until you saved the result file.
I'm not a huge fan or anything, FWIW...-ewemoa (April 13, 2011, 06:20 AM)
... it can do the cutting without re-encoding the file. Not only is this a lot faster than re-encoding, but it also doesn't destroy quality, which re-encoding does. If there's other programs that can do this direct cutting, let me know - does Code-it do that, Curt?-f0dder (April 13, 2011, 12:44 PM)

... cut out pieces of a MP3 without having to decode that MP3 to a non-encoded PCM (wave)-file.
MP3Cutter cuts the MP3 at the frame level so it doesn't degrade the quality of your MP3.
This way of editing has one major downside:
special effects like: normalizing, fading and adding things like a flanger or an echo are not possible.
If you want these kind of "effects" you'll need to decode the MP3 stream into an un-encoded PCM format which can then be processed
I think I'd remember what to do with Audacity, but I imagine it would take a fair bit longer to finish because of the exporting to mp3...For comparison, I tried Audacity's procedure.-ewemoa (April 13, 2011, 06:20 AM)
To remove labels without affecting other labels: Single-click in the text of an individual label, then press the <Delete> or <Backspace> key (as appropriate) on your keyboard until the text is removed. Once the label is empty of text, press <Delete> or <Backspace> once more to delete the label. You can also remove one or more labels without affecting other labels by selecting any region extending over (or at least touching) the label edges(s), then choose Edit > Split Cut.
Curt, this is a big if, but: if you're currently de- and re-encoding MP3s "just" for the purpose of normalizing, may I suggest you look into Replay Gainw? The idea is to simple scan the MP3s, and add tags with information of track and album volume levels, so a supporting player can do the normalization instead of destroying audio by re-encoding :)-f0dder (April 14, 2011, 01:45 AM)
Lossless Gain Adjustment
The bad news: This software can only adjust the volume of your mp3 files in steps of 1.5 dB.
The good news: 1.5 dB is a small enough step for most practical purposes. Most humans can just barely hear a volume change of 1 dB.
Some other good news is that this volume adjustment is completely lossless. In other words, if you adjust an mp3 by -6 dB and then if you change your mind, you can adjust it again by +6 dB and it will be exactly the same as it was before you made the first adjustment.-Code-it MP3 Volume Normalizer

Audacity steals focus during "Export Multiple" (http://forum.audacityteam.org/viewtopic.php?f=14&t=16922)...guess how many times...this is repeatedly annoying especially because if you happen to be typing elsewhere not only are you interrupted, you may accidentally cancel one of the exports...I think I've come across a work-around -- use of virtual desktops. Switching away from the desktop that audacity is running on seems to be effective in not being bothered by audacity-focus-stealing. May be this method is more generally applicable -- though perhaps how well it works may depend on application-specific behavior and/or one's window manager / virtual desktop configuration(s).-ewemoa (April 14, 2011, 04:54 AM)
