A: Spectroid uses dBFS (Full Scale) where 0 dB is the maximum power that the microphone can measure, so the decibel values are negative because the measured power is less than the maximum power. Most models will learn to ignore the noise over time, which makes them robust even against other (more realistic) noise sources.
