AGC2 won't amplify the background noise above -50 dBFS, which also caps the gain for a voice barely above that noise: a distant talker ended up 5 dB quieter than a near one with noise suppression on, 12 dB with it off. A "Boost quiet speech" setting (0-20 dB, default 0) raises the cap, live, on desktop and Android. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
