Audio Editor Only: Global Analysis

In the Audio Editor, you can perform an advanced analysis of your audio to identify areas with specific properties. This helps you to find problem areas such as glitches or clipped samples. You can also check general information, such as the pitch of a sound.

If you analyze a section of an audio file, WaveLab Pro scans the section or the audio file and extracts information, which is displayed in the dialog. WaveLab Pro also marks sections of the file that meet specific characteristics; for example, sections that are very loud or almost silent. You can then navigate between these points, set markers, or zoom in on markers. Most of the tabs allow you to determine exactly how to perform the analysis. Each tab focuses on a particular area for the analysis.

The Global Analysis dialog consists of the following tabs, which represent different types of analysis:

  • The Peaks tab allows you to identify individual samples with very high values.

  • The Loudness tab allows you to identify sections with a high intensity.

  • The Pitch tab allows you to determine the exact pitch of a sound or section.

  • The Extra tab provides information about DC offsets and the significant bit depth.

  • The Errors tab allows you to find glitches and sections where the audio is clipped.

Most of the analysis types display “hot points”; that is, positions in the file that indicate peaks, glitches, etc.
