| Version | Published | Release Notes | Action |
|---|---|---|---|
| 1.3.1 | Added the Edge Boolean , Eb allowing the reference frequency to either be selected as a center or edge frequency. |
||
| 1.3.0 | 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 | 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 | Updated program to satisfy ANSI S1.6 for full octave bands and third octave bands. |
||
| 1.0.0 | Fixed a bug in rounding the frequencies. Previoius version did not allow frequencies less than 1 Hz. |
