fbank [options] [file]

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

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

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

            freq=a[-b]

where ‘a’ and ‘b’ are channel numbers: 0,2,3,... (the lowest centre-frequencychannel has the lowest channel number, 0).The upper limit ‘b’ is optional, and when it is missing then the range ofchannels 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 itis converted to a channel number using the "closest" channel numberin 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
