1 .TH EDWAVE 1 "1 September 1993" | |
2 | |
3 .SH NAME | |
4 edwave \- Edit a given range of a wave. | |
5 | |
6 .SH SYNTAX | |
7 edwave [options] [filename] | |
8 | |
9 .SH DESCRIPTION | |
10 Editing operations extract or delete a given time range of a given wave, | |
11 and the results are written on the stdout. | |
12 | |
13 .SH OPTIONS | |
14 | |
15 1. range. | |
16 | |
17 The range option specifies the stretch of the wave for the editing operation | |
18 by: | |
19 | |
20 .nf | |
21 range=a[-b] | |
22 .fi | |
23 | |
24 The upper limit `b' is optional, and when it is missing then the range | |
25 is a single sample of the given type, otherwise `a' and `b' are inclusive range limits. | |
26 The strings "min" and "max" are recognised as extreme limits | |
27 ("min" = start of file, "max" = end of file), | |
28 otherwise the values of `a' and `b' are sample numbers: 0,1,2,... | |
29 Values given with time units (ms or s) are converted to samples using | |
30 the given samplerate option. | |
31 | |
32 2. operation. | |
33 | |
34 The `operation' option sets the edit operation to either: | |
35 | |
36 .nf | |
37 operation=extract | |
38 or | |
39 operation=delete | |
40 .fi | |
41 | |
42 The extract operation outputs the part of the input which is inclusively | |
43 within the given range. | |
44 The delete operation outputs the part of the input which is NOT inclusively | |
45 within the given range. | |
46 | |
47 3. type. | |
48 | |
49 The datatype of input and output. Known types are in the list: | |
50 char, short, int, float, double, ascii. The ascii type is interpreted as one | |
51 sample per line. | |
52 | |
53 4. size. | |
54 | |
55 Print the size of the wave on the stdout in given units. | |
56 Units are seconds ("size=s"), milliseconds ("size=ms"), or samples ("size=on"). | |
57 Sizes in time units are calculated using the given `samplerate' option. | |
