Max Level Attenuation

Macro: UseMaxLevel

When Use Level is active, this control specifies how far it can go. Normally, the effective Level adjustment is no bigger than needed to reach the next attenuator step, typically a few dB at most. This allows the highest output quality (minimum quantization noise and distortion). But when you try to reduce the sound lower than the combined range of the Wave and Master attenuators, the Level control may be called upon to provide more adjustment. The default here is to allow up to 96 dB to be provided by Level, which is essentially the entire range of a 16-bit sound card. When the overall combination of Wave, Master, and Level is exceeded, the output is put into the 'Mute' condition. If you restrict the maximum Level contribution, the Mute condition will be applied sooner.

Macro Notes:

UseLevelMax=60 sets the Max Level contribution to the equivalent of 60 dB.

UseLevelMax=>1 increases the Max Level value by 1 dB, and UseLevelMax=>-1 decreases it by 1 dB.

Note that this command is enabled only when both Use dB and Use Level are active. Otherwise, the macro may abort with an error message. To be safe, give UseCal=dB followed by UseLevel=1 before UseLevelMax.
