An Mp3 file consists of thousands of frames. Each frame is about 30 milisecons long. musiCutter allows you to split one mp3 file into more mp3s exactly between frames.
Due to the format of mp3, small parts of frame data may be stored in the previous frame (bit reservoir).
If mp3 parts are chained before they are decoded, you'll get "TRUE" gapless output, but AFAIK there is no player using this method.
Today gapless players are decoding mp3 and then concatenating - you'll get "NEAR" gapless output, because data in the bit reservoir will be lost (gaps should be inaudible). If you need original mp3, you concatenate these parts and you'll get original mp3.
1. Select page "Cut points"
2. Select mp3 or ogg file to split in upper part of window
3. Optionally adjust the output directory
4. Fill "Start" and "FileName" in the grid either manually using "Add" button or import the values form CUE sheet or XMCD file or plain text using button "Import from file..."
5. Hit "Cut now!" button
Notes: - If the FileName of the cut point is empty, the fragment is skipped & not written to disk.
- If you are going to cut an .ogg file and click "Cut now!" while holding shift, the batch file will be created instread of executing the vcut.exe. Then you have to run the batch file manually. Use this to track down the possible errors.
1. Select page "Files to join"
2. Select files in upper part of window
3. Use buttons Add/Delete to manage files in list
4. You can reorder the files in list using mouse (drag&drop)
5. Adjust "Output filename" if neccessary
6. Hit "Join now!" button
MP3 files are joined carefully, VBR headers are skipped and ID3 tags are removed and all invalid frames are not copyied. If frame is incomplete (common case - the last frame of most mp3 files is usually shorter than it should be), it is padded with zeros to have correct length.
Ogg files are joined simply as with "copy /b file1.ogg+file2.ogg result.ogg". The result is .ogg file containing "chained bitstreams" which is 100% valid, but unfortunately vcut.exe can't handle it further.
Ogg files are cut by vcut.exe, at present there is limitation - vcut.exe can't handle "chained ogg bitstreams" - it will show an error when you try to cut such a .ogg file.
Original files will not be deleted, so don't hesistate to experiment.

This is by far one of the most useful music joining programs I have used. Most that I have seen are command line and/or needlessly complicated. This one has a simple UI, is easy, is intuitive, and best of all it is FAST. I highly recommend using this for things like audiobooks or if you want a full album mp3. Keep in mind that since it is so simple, it won't give options such as what bitrate to have for the output, so you just have to make sure your input files are at the rate that you want before you start.
You can rip a whole CD as one wav, and then encode it as one mp3 and split it. Using gapless mp3player you'll get virtually gapless output.
