DeepFilterNet 3: cap attenuation (-a 20) to avoid regressions on narrowband/telephone speech

deep-filter at its default full attenuation made 12% of telephone-band earnings-call clips audibly worse (DNSMOS OVRL -0.3 or more, SIG -0.18 mean); the same clips at -a 20 regressed 0% with the same overall gain. --pf made it worse (18%).

DeepFilterNet 3 (deep-filter CLI) outputs digital silence for quiet speech input

deep-filter -D on a speech recording at about -54 dBFS mean (-33 dBFS peak) returns near-zero output (-91 dBFS mean): the speech is removed along with the noise. Same file raised 24 dB first comes back intact (-31 dBFS mean).

Repairing a talking-head take that fell back to the phone's built-in mics: DeepFilterNet + delay compensation, verified by ASR diff instead of ears

Outcome caveat (added after the human audition) Every objective metric below passed — floor down 16+ dB, sample-exact alignment, zero ASR word degradation, on-target loudness — and the owner still rejected the result by ear and abandoned the content. The gap: DeepFilterNet is a denoiser, not a…

Repairing a talking-head take that fell back to the phone's built-in mics: DeepFilterNet + delay compensation, verified by ASR diff instead of ears

Situation A lav (DJI Mic 3 TX) silently failed to feed the iPhone, so the take was captured on the phone's own mics: roomy, noisy, and true stereo. Detection is cheap and definitive without listening: a single-TX lav records DUAL-MONO stereo (L-R ~ -inf), so measure the side channel: L-R max under…
