DESCRIPTION

Print centre-frequency and bandwidth information for a given
gammatone filterbank on the stdout.

Parameters specifying a filterbank may be given as arguments
(channels, mincf, maxcf, dencf, bwmin, quality), or may be read from
an AIM output header if the option ‘input=on’.

Centre-frequency and bandwidth information is printed for a selected range of
filterbank channels, specified using the ‘freq’ option:

         freq=a[-b]

where ‘a’ and ‘b’ are channel numbers: 0,2,3,... (the lowest centre-frequency
channel has the lowest channel number, 0).
The upper limit ‘b’ is optional, and when it is missing then the range of
channels is a single channel, otherwise ‘a’ and ‘b’ are inclusive limits.
The strings "min" and "max" are recognised as extreme limits
("min" is the lowest frequency channel, "max" is the highest frequency channel).
Either range limit can take frequency units (Hz or kHz), in which case it
is converted to a channel number using the "closest" channel number
in the filterbank to the specified centre-frequency.

For example:

        freq=5 channel 5
        freq=1kHz channel number with centre-freq closest to 1kHz
        freq=max highest centre-freq channel
        freq=10-max channel 10 to the highest centre-freq channel
        freq=min-15 channel 0 to 15
