The CPU column was guessed (DeepFilterNet "25-50%", DTLN "10-20%") with no
unit, so it read like Task Manager's whole-CPU figure and looked wildly off.
Measured with each model running exactly as Lotus Call runs it (real-time
speech, browser process CPU time from /proc minus a no-model baseline,
Ryzen 7 PRO 4750GE): DeepFilterNet ~30%, DTLN ~9%, RNNoise ~3%, Speex ~2%
of one core. Label it "one core" and explain the Task Manager relation.
DTLN's download was listed as ~4 MB but fetches ~20 MB (17 MB worklet with
the runtime inlined, plus 4 MB of models); DFN's ~18 MB is right (17.6 MB).
