Radio and TV uses full spectrum, so they set channels to 0, this will
define a center frequency only. The spectrum is then processed by the
applications and not by libsdr.
The sample rate must be a factor of 1e9, so that time stamps work
and signal has no gaps/glitchs.

Rename dbm0 (level) to speech (level)

Fixed performance issue with IIR filter
...
Passing samples with zero value (0.0) causes very slow processing of

To solve this, I add a very small number to each input sample.
