Claim 11:
12. A system comprising:
data processing hardware; and
memory hardware in communication with the data processing hardware, the memory hardware storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations comprising:
establishing digital communication between a first user device and a second user device using a first codec;
selecting, based on an input signal representing an estimated unfiltered available bandwidth for the digital communication satisfying a first filter selection threshold, a first filter of two or more filters;
filtering the input signal using the first filter;
determining that the filtered input signal satisfies a first channel bandwidth threshold; and
in response to determining that the filtered input signal satisfies the first channel bandwidth threshold, selecting a second codec different from the first codec for further digital communication between the first user device and the second user device.
