A command that creates a BarkFilter object from every selected Sound object by band filtering in the frequency domain with a bank of filters.
The filter functions used are:
| 10 log H(z) = 7 - 7.5 * (zc - z - 0.215) - 17.5 * √ (0.196 + (zc - z - 0.215)2) |
where zc is the central (resonance) frequency of the filter in Bark. The bandwidths of these filters are constant and equal 1 Bark.
