Is there a good (freeware) and simple to use MP3 splitter available which
will (for instance) split one massive album MP3 into separate tracks
automatically? If not, I can do it manually but don't really want to
convert to wave first if possible.
TIA
MP3 Book Resizer 1.0
Freeware by Xenolith
In the following paragraphs, mp3 will stand for any MPEG-1 or 2, Layer
1, 2, or 3 file, which covers the file extensions mp1, mp2, and mp3.
Audiobooks are typically made up of large mp3s. I wrote this program to
convert these large files into many smaller ones to make it easier to
listen to them on a portable device. I call this "resizing." I've seen
programs that split one mp3 into many or combine many into one, but I
haven't found one that lets you take any number of mp3s and resize them
into any other number of mp3s, at least without defining a bunch of cue
points. If there is such a program, hopefully this one is more
straightforward.
Resizing can be done based on time, byte size, or number of files. For
example, if you have six 10-minute mp3s, you can resize them into 20
3-minute mp3s or 10 6-minute mp3s, etc. You could also combine smaller
mp3s into a larger file; the input and output file sizes can be anything
reasonable.
The program splits mp3s on frame boundaries and ignores everything in
the input files but valid frames. All values in the time, size, and
number boxes are close estimates of the actual times, sizes, or number
of files making up the output files. It's impossible to be exact
without cutting into a frame. When resizing non-mp3 files, the output
file sizes will exactly be the number in the size field.
The output name pattern box works like this: If you want your output
(resized) files to be named The Book 001.mp3, The Book 002.mp3, etc,
then put The Book *.mp3 in the box.
This program does not write any ID3 tags to the output files because I
consider those files temporary. They should be deleted when you are
done listening, and the original files should be saved. Splitting might
occur in the middle of a word/sentence. That doesn't bother me, but I'd
hate for such files to be posted to a newsgroup.
Features
-supports MPEG 1, 2, and 2.5, Layers 1, 2, and 3
-remembers your last split settings, position/size on the screen, and
column widths
-easy drag and drop/rearranging/sorting/removing of files. You can drop
folders, too
-to sort by a column, click on the column header
-to maximize the width of a column, double-click on the divider to the
right of the column header
-splits on frame boundaries and only copies valid frames into the output
files
-any other file type can be resized; for example several text files
could be concatenated into one file
-displays the number of sync errors in each mp3 and where they are in
the file in hh:mm:ss
-shows each mp3's type and frequency because only files of the same type
and frequency can be resized. Bitrate doesn't matter. Bitrate and time
are shown for no particular reason.
-operates without reencoding
Special behavior
-if an mp3 is too damaged it cannot be added to the list
-if a file is added to the list that is not an mp1, mp2, or mp3, then
splitting by time will be disabled, so all mpeg audio files must have
one of those 3 extensions
-a file can only be split into up to 999 parts, otherwise "Start" is
disabled
-adding a file to the list puts that file's path in the output path box
because the program assumes you want the output files to be in the same
or nearby directory as the input files
-files of zero length are ignored
-the maximum time of an output file is 99:59:59
-the maximum size of an output file is 2,147,483,647 bytes
-the number of sync errors a.k.a. missing frame headers may be different
than other programs report. Only one error per second of audio is
reported.
-creates an initialization file called MP3BookResizer.ini in the same
folder as the program. If this file is deleted, then "factory settings"
are restored.
-many mp3 players and CD burning programs don't report the correct
playing time for VBR mp3s. This program does, and if you set the Number
field to 1, then you can see the correct total time for the VBR mp3s in
question; useful for determining what you can fit on an audio CD
