octspace

Create logarithmic spacing with 1/N-th octave bands over a specified frequency range.

This function creates log spacing for 1/n Octave frequency bands for the range of frequencies
containing [fmin, fmax]. By default, the reference center-band frequency is set at 1 kHz and
calculations are preformed using a Base 2 method, but can be changed using the variable input.

The reference center-band frequency can be specified as any numerical value.
Available calculation methods are Base 2 and Base 10.
