<dt>A:</dt><dd>The graphs titled "native SR" run encoder/decoder at the native input/output sampling-rate per operating point. This is 16 kHz for WB, 32 kHz for SWB etc. The graphs titled "48 kHz" use 48 kHz input/output sampling rate, independent of the supported bandwidth, which is set by using the "-max_band" commandline switch.</dd>

An upwards arrow means that the score got higher (i.e. worse), downwards arrow arrow means that the score got lower (i.e. better), and a rightwards arrow means that the score was kept constant (within a 1% margin).
