Hi!

That can mean a couple of different things. Which "octave filter" are you referring to? Is it related to one of our chips? Or to some of our software?

The term octave has parallels in music. Each note in the next octave has double the frequency of the corresponding note.

When using Octave band filters the frequency band of each subsequent filter doubles towards the higher frequencies (or halves towards the lower frequencies).

Filters designed with the help of the Octave program could also be called that. :D
