1 .TH GAUSS 1 "1 September 1993" | |
2 | |
3 .SH NAME | |
4 gauss \- generate a Gaussian window. | |
5 | |
6 .SH SYNTAX | |
7 gauss [option] | |
8 | |
9 .SH DESCRIPTION | |
10 Generate a Gaussian window on the stdout in binary shorts or floats for a | |
11 given variance over a given range of standard deviations. | |
12 | |
13 .SH OPTIONS | |
14 | |
15 1. variance, range | |
16 | |
17 The variance of the Gaussian window and its ordinal range in standard | |
18 deviations either side of the mode. | |
19 The size of the window in samples is given by: | |
20 | |
21 .nf | |
22 [ 2 * range * sqrt( variance ) ] samples + 1 sample | |
23 .fi | |
24 | |
25 The variance can be given with time units (ms or s) or samples (no | |
26 units). Time units are converted to samples using the given `samplerate' | |
27 option. | |
28 | |
29 2. normalize | |
30 | |
31 If "normalize=off" then the window has unit amplitude at the mode. | |
32 If "normalize=on" then the window is scaled for unit area. | |
33 | |
34 3. scale | |
35 | |
36 A scale factor for the output. | |
37 | |
38 4. type | |
39 | |
40 Output datatype ("type=short" or "type=float"). | |
41 | |
