PROGRAM:
NAME
qmp3cut - extract and/or delete parts of a mp3 file
SYNOPSIS
qmp3cut [option]... file
DESCRIPTION
qmp3cut allows to extract and/or delete a fragment of a mp3 file. some parameters must be
supplied in order to define the start/size/end cut points and what to do then: either the
fragment must be copied to another file or erased from the file (or both)
GENERAL OPTIONS
-d, --delete
deletes the fragment from the file. if option --output is used, deletion action is
always done after fragment extraction.
-h, --help
show a brief help and exit.
-o <outfile>, --output=<outfile>
outfile is the file where the frames contained in the specified fragment will be
copied.
-v, --verbose
verbose.
-V, --version
show version and exit.
CUT OPTIONS
cut options are used to specify at which frame the fragment begins (options -b or -B),
ends (options -e and -E), or which size it has (option -s). at least, one cut option must
be specified. neither the options -b and -B, and the options -e and -E can be used
together; also, a begin, end and size option can be used at the same time.
by default, the fragment begins at the first frame and ends at the last frame; there's no
default value for size.
all the values are treated as a frame number unless a format specifier is used. see the
FORMATS section below for information. values must be positive integer.
-b <begin>[<format>], --set-begin-from-eof=<begin>[<format>]
begin specifies the first frame of the file that belongs to the cut counting from
the end of the file.
-B <begin>[<format>], --set-begin=<begin>[<format>]
begin specifies the first frame of the file that belongs to the cut counting from
the beginning of the file.
-e <end>[<format>], --set-end-from-eof=<end>[<format>]
end specifies the last frame of the file that belongs to the cut counting from the
end of the file.
-E <end>[<format>], --set-end=<end>[<format>]
end specifies the last frame of the file that belongs to the cut counting from the
beginning of the file.
-s <size>[<format>], --set-size=<size>[<format>]
size specifies the number of frames contained in the cut.
-S <begin>-<end>, --slice <begin>-<end>
slice specifies the starting and ending points of the cut as a timeslice, which is
to say, two time specifications ([[h:]m:]s[.ms]) joined by a hyphen.
FORMATS
cut options can have also an optional modifier. if this modifier is not used, then the
value provided with the corresponding cut option will be interpreted as a number of
frames. since most of the times will be difficult to specify a cut in terms of frames, the
following modifiers are provided:
j value is interpreted as milliseconds.
m value is interpreted as minutes.
s value is interpreted as seconds.
b value is interpreted as bytes.
k value is interpreted as kbytes (1024 bytes).
M value is interpreted as megabytes (1024 kbytes).
in either case, the values specified will be rounded to get an integer number of frames.
EXAMPLES
here are some examples:
to get the last ten seconds of a file:
qmp3cut -b 10s -o outfile.mp3 infile.mp3
two ways of getting the first minute of a file:
qmp3cut -E 1m -o outfile.mp3 infile.mp3
qmp3cut -s 1m -o outfile.mp3 infile.mp3
three ways of getting the second quarter of a file:
qmp3cut -S 15:0-30:0 -o outfile.mp3 infile.mp3
qmp3cut -B 15m -E 30m -o outfile.mp3 infile.mp3
qmp3cut -s 15m -E 30m -o outfile.mp3 infile.mp3
qmp3cut -B 15m -s 15m -o outfile.mp3 infile.mp3
NOTES
if neither the options --output nor --delete are specified, the program will do nothing.
