.TH EDWAVE 1 "1 September 1993"

.SH NAME
edwave \-  Edit a given range of a wave.

.SH SYNTAX
edwave [options] [filename]

.SH DESCRIPTION
Editing operations extract or delete a given time range of a given wave,
and the results are written on the stdout.

.SH OPTIONS

1. range.

The range option specifies the stretch of the wave for the editing operation
by:

.nf
	    range=a[-b]
.fi

The upper limit `b' is optional, and when it is missing then the range
is a single sample of the given type, otherwise `a' and `b' are inclusive range limits.
The strings "min" and "max" are recognised as extreme limits
("min" = start of file, "max" = end of file),
otherwise the values of `a' and `b' are sample numbers: 0,1,2,...
Values given with time units (ms or s) are converted to samples using
the given samplerate option.

2. operation.

The `operation' option sets the edit operation to either:

.nf
	    operation=extract
or
	    operation=delete
.fi

The extract operation outputs the part of the input which is inclusively
within the given range.
The delete operation outputs the part of the input which is NOT inclusively
within the given range.

3. type.

The datatype of input and output. Known types are in the list:
char, short, int, float, double, ascii. The ascii type is interpreted as one
sample per line.

4. size.

Print the size of the wave on the stdout in given units.
Units are seconds ("size=s"), milliseconds ("size=ms"), or samples ("size=on").
Sizes in time units are calculated using the given `samplerate' option.
