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
