The default frame rate used to calculate frame values.

Frame values are useful when trying to synchronize sound with animation. Most animation players specify a playback frame rate at which video frames are shown to the user. If you are using an animation that has a frame rate of 15.0 frames per second, you would set the frame rate to 15.0. When status values are displayed, they will be shown in values of frames. This allows you to find the frame to which a given point in the sound file corresponds.

The number of beats in each measure for displaying in measures and beats. For example, 2/4 time would have two beats per measure.

This setting will also be used in the Edit Tempo window.

The number of beats per minute, i.e. the tempo of a song for displaying lengths.

This setting will also be used in the Edit Tempo window.

The amount of audio data surrounding the cursor used to calculate the RMS level in the Levels toolbar.

The amount of sound data surrounding the cursor used when searching for a peak level to display in the Levels toolbar.

Choose a setting from the drop-down list or type a value in the box to calibrate the Peak Meters to their associated levels on the peak meters.

VU meters display sound in dB VU, where 0 VU is a reference level, and there is headroom above 0 VU. The peak level indicators in Sound Forge Pro show peaks in dB FS (decibels relative to maximum level, full scale, FS).

With digital audio, there is no headroom above 0 dB FS. Choosing a setting from this drop-down list subtracts a nominal dB value from the VU meters so that a signal displayed on the VU meters remains slightly below 0 dB on the peak meters.

Type a value in the box to set the amount of data surrounding the cursor that will be used to calculate levels in the VU meters.

This setting has no effect on the PPM scales, which use fixed integration times:

• UK PPM: 10 ms

• EBU PPM: 10 ms

• DIN PPM: 5 ms

• Nordic PPM: 5 ms

For the Loudness Norm you can choose either EBU R128 or ATSC A 85 in their respective current versions. The standard specifies the target value in LUFS for program loudness and define the tolerance range in LU used in the loudness display.

Select this check box if you want to treat audio with six channels as surround audio when metering loudness (a gain of ~1.5 dB is applied to the left and right surround channels). When the check box is cleared, all channels contribute equally to the loudness measurement.

Activate this check box if Loudness Log files are to be opened automatically in the default text editor when Extras> Generate Loudness Log is selected.
