Playback gain (post mpx decoding / analysis) is *not* adjustable ; per-file in MpxTool. ; Gain is linear, and calculated as follows: 4096 is no gain/no attenuation (unity gain, 0dB). ; Example, file overshoots to 108% ; 100 / 108 = 0.9259 ; 0.9259 = 3793 ; Thus, gain_x=3793 will make the file peak at 100%, without having to alter the recording. ; By the way, the 8100 recording is WAY too hot (114% peak!) ; but let's allow it 10% extra, and only count 104%. let's call it the grandfather clause! ; Many 8100's were used with composite clippers which would eliminate the overshoot ; with minimal distortion penalty, as the overshoots are very brief. gain_a=4015 gain_b=4015 gain_c=3938 gain_d=4055 gain_e=4096 gain_f=3864 samplerate=192000
