The low level; it's in the USB PG drive 's saved wav itself. Increasing it also increases the noise floor. Why i started this post LoL. IMO the minimum level with a 16dbit wav is -12dB, what i learned 'officially' in the old days of audio for video (especially TV) mixing; the norm back then when digital audio first came around, with Sony PCM masters & later DAT recorders, all 16bit. I still have an expensive gastubed fast (analog) peak level meter somewhere because of that. A norm abandoned tthese days because every wants to be loudest, especially with commercials. F.
