5 gammatone filterbank. | |

10 .SH DESCRIPTION | |
11 Print centre-frequency and bandwidth information for a given | |
12 gammatone filterbank on the stdout. | |
13 | |
14 Parameters specifying a filterbank may be given as arguments | |
15 (channels, mincf, maxcf, dencf, bwmin, quality), or may be read from | |
16 an AIM output header if the option `input=on'. | |
17 | |
18 Centre-frequency and bandwidth information is printed for a selected range of | |
19 filterbank channels, specified using the `freq' option: | |
20 | |
21 .nf | |
22 freq=a[-b] | |
23 .fi | |
24 | |
25 where `a' and `b' are channel numbers: 0,2,3,... (the lowest centre-frequency | |
26 channel has the lowest channel number, 0). | |
27 The upper limit `b' is optional, and when it is missing then the range of | |
28 channels is a single channel, otherwise `a' and `b' are inclusive limits. | |
29 The strings "min" and "max" are recognised as extreme limits | |
30 ("min" is the lowest frequency channel, "max" is the highest frequency channel). | |
31 Either range limit can take frequency units (Hz or kHz), in which case it | |
32 is converted to a channel number using the "closest" channel number | |
33 in the filterbank to the specified centre-frequency. | |
34 | |
35 .nf | |
36 For example: | |
37 | |
38 freq=5 channel 5 | |
39 freq=1kHz channel number with centre-freq closest to 1kHz | |
40 freq=max highest centre-freq channel | |
41 freq=10-max channel 10 to the highest centre-freq channel | |
42 freq=min-15 channel 0 to 15 | |
