I've looked around and not found details on the expected frequency range the Speex codec can be expected to carry. Is there any documentation available or a table of some sort that has been compiled which would give an indication of the frequency range based on the various compression options in speex?

The "frequency range" (which we call bandwidth) is whatever the bandwidth of what you encode, of course bounded by the Nyquist rate (sampling freq/2).

Then if I may trouble you all with a followup thought: Is there however a low-end of the spectrum that I should expect Speex (with and/or without noise cancelling) to cut-off due to compression loss or other algorithm related reasons? Could Speex (at any given setting) properly carry a 25-67Hz tone for instance? Sincerely, Baldvin
