Choose a setting from the drop-down list to choose the format that will be used to display the Cursor position, Minimum sample position, and Maximum sample position values.

Choose a setting from the drop-down list to choose the format that will be used to display the Sample value at cursor, Minimum sample value, Maximum sample value, RMS level, and Average value values.

The cursor position from the beginning of the audio file.

Value of the sample at the cursor position.

The maximum and minimum sample values and the locations where they occur.

With the help of these values you can determine whether there are overloads in the audio file. It can also be used to determine the noise level of a signal for use with the Noise Gate effect. For example, to find the noise amplitude, run the Statistics function on a region of noisy silence.

The Root Mean Square of the sample values relative to the RMS value of a maximum-amplitude square wave (the loudest possible recording).

When used on short intervals, this value relates to the volume level of the sound file. However, if used on a large selection with large volume variation, this value becomes less meaningful. For another way to measure loudness, use the Scan Levels button in the Normalize dialog.

The sum of all sample values in the selected region divided by the number of samples.

An average value that does not equal zero (-inf dB) can indicate a DC offset.

The number of times per second that the waveform changes from a negative value to a positive value.

This value can be used as a rough estimate of the frequency of the audio data for very simple waveforms.

The maximum true peak sample value and the location where it occurs. This value displays the peak level in dB FS.

Please note that true peaks are calculated using a higher sample rate than the Maximum sample position and Maximum sample value items for increased accuracy.

The maximum filtered true peak sample value and the location where it occurs. This value displays the peak level in dB FS. Peak levels may be miscalculated if audio signals are asymmetrical or if a DC offset is present. Filtered true peaks are calculated as the maximum of the filtered and unfiltered signals.

The Loudness Meters show data about an audio file's momentary loudness, short-term loudness, integrated (overall) loudness, and loudness range. You can use these values when mastering for broadcast to ensure compliance with loudness standards (such as the CALM Act).

The following values are calculated:

• The Integrated value represents the integrated loudness — in loudness units full scale (LUFS) — across all audio channels over the duration of the program.

• The LRA meter represents the loudness range — in loudness units — of the momentary and short-term levels. The Loudness Range measurement provides a standardized method of determining the dynamic range of the signal.

• The Maximum Short-Term value represents the maximum short-term loudness — in loudness units full scale (LUFS) — across all audio channels based on 3-second integration windows.

• The Maximum Momentary value represents the maximum momentary loudness — in loudness units full scale — across all audio channels based on 400-millisecond integration windows.

TIP Select the Enable surround processing for files with 6 channels check box on the Status tab of the Preferences dialog if you want to treat audio with six channels as surround audio when measuring 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.
