WAVSPLIT 1.1.0
splits wavfiles into tracks
licensed under GPL

................................
Based on wavplay by Warren W. Gay and
gsplit by the Free Software Foundation
Written by Tobias Weihmann (tobias@fomalhaut.de)
Updated to V1.1.0 by Alan Fitch (apfitch@ieee.org)
INTRODUCTION / OVERVIEW
This small program splits large wav files at given time positions.
This is very handy if you want to transfer your gramophone records
to CDs. To find out split positions you can use any Wav player or
editor with a time display. You'll get the splitting done much faster
and reliably than with complex algorithms, which split your a capella
songs in pieces and won't process live albums.
INSTALLATION
After unpacking the tarball issue the command
make && make install
to start the compilation process and copy the program to /usr/local/bin.
(If you don't have a root account, simply issue "make" and copy the tool
manually to the desired location)
There are some man pages - you can copy these to a sensible place, e.g.
/usr/share/man/man1 on a RedHat system.
Note for all 64-bit systems: when your `long'-type vars are 64 bit, .wav
headers are not read/written correctly (=bug). If you replace every `long'
with an `int' (or other 32-bit type), everything should be fine.
To run WavSplit, issue the command
wavsplit WAV-FILE mm:ss [mm:ss] [mm:ss]...
For example,
wavsplit firstrecord.wav 5:23 8:10
will create a folder, containing three files. '01.wav' containing
the track from 0:00 to 5:23, '02.wav' containing the track between
5:23 and 8:10 and the '03.wav' containg the rest of the data. The
original file is not touched.
You can also specify splits in just seconds, e.g.
wavsplit firstrecord.wav 323 490
This is handy if your wave editor reports times in seconds. The seconds
values may be specified with a decimal place, e.g.
wavsplit firstrecord.wav 323.5 490.15
See the help for also specifying times using hours, and frames. To get
help type
wavsplit
or
wavsplit -h
or
wavsplit --help
To find out the split positions use a wav player with a time display,
like Xmms, or an editor such as Audacity. Each time you find a new track,
add the split position to the WavSplit on the commandline.
Of course, you can also save time locating the exact split positions
by using the length information printed on the record cover.
IMPORTANT
Tested with standard 44100Hz 16 Bit Stereo WAVs, but should work for
other WAVs, too. Tested on Suse Linux 6.3 for Intel, and on RedHat
7.3 and 9 for Intel. Please tell me if WavSplit works or does not work on
other systems.
Your arguments are not checked at the moment. Thus, your split positions
have to be in correct order for the program to be successfull, e.g. 5:23
has to be placed before 8:10.
QUESTIONS
Q: There are programs (like GramoFile) which autodetect the tracks. Isn't
this better?
A: None of them can split live albums. Also, even though they use complex
algorithms, it often happens they are wrong, especially if there are pau-
ses within the tracks (most often in songs without background instruments)
GramoFile, while being a very powerful program, was very slow compared to
simple WavSplit on my good old P200.
Q: There are GUI programs for that.
A: Even though there are some wave editors, which don't coredump when
trying to open a 100 MB file, loading, displaying and saving files of
this size takes some time. Broadcast is relatively fast, but extracting
songs is a pain. First I wanted to writer a GUI splitter but I soon
noticed how important it is to have a fluent zoomable and scollable
display or the user will get lost in the chaotic waveforms. I did not
want to spend my time writting a professional music editor, but listening
to my gramophone records from CD. WavSplit is a quick and dirty hack, but
it works - fast.
Q: Why don't you use the CD TOC (Table of Contents)?
A: You won't have immediate verification and you can't create MP3s without
rereading the audio data from the CD.

See the eMail address and URL above. On my homepage you will also find
an interview with the lead programmer of the legendary C64 game Summer
Games and a German Tutorial on building an MP3 player into your car.
Bug reports, fixes and additions welcome. However, WavSplit is a one
time hack, not an ongoing project of mine.
