Whether ReplayGain changes the output: false when the source mode is none or auto, or the processing mode is none.
Preamp applied to tracks without ReplayGain, in dB.
Preamp applied to tracks that carry ReplayGain, in dB.
What is applied: gain the gain only, peak peak limiting only, gain_and_peak both, none nothing.
Where the gain applied during playback comes from: none applies no gain, track and album use the respective stored value, auto follows the playback order (track gain in shuffle, album gain otherwise).
Always true here; a failed call resolves with ApiFailure instead.
