Nth Octave Frequency Bands
This program calculates the 1/N-octave-band center and edge frequencies from min_f to max_f (Hz). The exact and nominal frequencies are output in arrays. The nominal frequencies are also output in a cell of string of characters for plotting purposes.
This program satisfies the frequency band requires established in ANSI S1.6 and ANSI S1.11.

---|---|---|---|
1.3.0.1 | Added the reference frequency, fr as an input variable and optimized the removal of fractional-octave-bands outside the range of min_f to max_f. |
||
1.3.0.0 | Revised the number of significant digits calculation for rounding. Limited the number of bands per octave from 1 to 10E12. A warning is issued if the number of bands is greater than 10E6. |
||
1.2.0.0 | Modified the even octave bands to have 1000 Hz as an edge frequency. Changed the number of significant digits calculation for rounding. Limited the number of bands per octave from 1 to 43. |
||
1.1.0.0 | Updated program to satisfy ANSI S1.6 for full octave bands and third octave bands. |
||
1.0.0.0 | Fixed a bug in rounding the frequencies. Previoius version did not allow frequencies less than 1 Hz. |
