An octave band is a frequency band that spans one octave. In this context an octave can be a factor of 2 or a factor of 10 0.3. To remove the ambiguity, an alternative name suggested for a factor of 100.3 is "dectave", a portmanteau of "decimal" and "octave". An octave of 1200 cents in musical pitch corresponds to a frequency ratio of   ⁠2/ 1 ⁠ ≈ 10 0.301.
