Elastic Audio Analysis

For more information, see the following topics:

File Timebase and Elastic Audio Analysis Icons

You can both calculate and clear Elastic Audio analysis for selected audio files in DigiBase browsers. Only AIFF and WAV files are supported for Elastic Audio analysis and processing. Any other file format (such as MP3) must be converted to AIFF or WAV for Elastic Audio analysis and processing.

Even though the MP3 file formats are not directly supported by Elastic Audio, you can import them into a WAV- or AIFF-based session and then use the converted files on Elastic Audio-enabled tracks. File formats that do not match the session are converted automatically on import.

For more information on Elastic Audio, see Elastic Audio.

To calculate Elastic Audio analysis:

1 In a DigiBase browser, select the files you want to analyze.

2 Do one of the following:

From the Browser menu, choose Calculate Elastic Analysis.

Right-click one of the selected files and choose Calculate Elastic Analysis from the pop-up menu.

Preview the file with the Audio Files Conform to Session Tempo option enabled.

Analyzed files are indicated by a check mark to the left of the file name.

Analyzed files in which a regular tempo was detected are updated as tick-based, display their duration in Bars|Beats, and display their native tempo in the Tempo column.

Analyzed files in which no tempo was detected remain sample-based. These files typically contain only a single transient (such as a snare hit) or they are longer files without a readily identifiable regular tempo (such as entire songs).

On Mac, if you do not see the Elastic Audio Analysis icon or the duration does not change to tick-based during the preview process, check the permissions for the folder in the Mac Finder. You must have write access of the directory for this feature to work.

To clear Elastic Audio analysis:

1 In a DigiBase browser, select the files with Elastic Audio analysis that you want to clear.

2 Do one of the following:

From the Browser menu, choose Clear Elastic Analysis.

– or – 

Right-click one of the selected files and choose Clear Elastic Analysis from the pop‑up menu.

Files cleared of Elastic Audio analysis data revert to sample timebase, display their duration in minutes and seconds, and do not report a tempo.
