I/O Options

The I/O tab lets you control Ozone's input/output meters and gain when bypassed.

See the Auto-Normalize Function page for info about auto-normalizing.

See the Gain When Bypassed Function page for info about the gain when bypassed feature.

Input/Output Meter Options

Enable meter Turns on or off the level meters

Show peak hold Turns on or off the peak hold display for the level meters

RMS or PPM PPM (Peak Program Material) is a fast peak meter that will allow you follow the peak values. If you are tracking the absolute peaks for possible clipping the PPM meter is appropriate.
RMS (Root Mean Square) is a software-based implementation of an analog style level meter. The RMS meter displays the average level calculated over a short window of time. The result is a meter that is appropriate if you are intersted in tracking the overall loudness. The RMS meter readout will typically be lower than an equivalent PPM meter, since it is averaging peaks into the overall loudness.

Peak hold time
If peak hold is on, clicking this button allows you to cycle through different peak hold times. The choices are 250 msec, 500 msec, 1000 msec, 5000 msec and infinite.

If set to infinite, the peak value will be held until you double click on the meter.

Integration time This setting only applies if the level meter is set to RMS. It lets you specify the integration time for the RMS calculation. In most RMS meters, the integration time is set to around 300 msec.

Readout
Allows you to control what is displayed by the numeric display on top of the meters: peak or actual (real time). If set to peak, the display will reflect the meter's peak value. If set to real time, the display will reflect the meter's actual value.
