Match volume across multiple files

If you plan to present a group of audio files on CD, the web, or elsewhere, use the Match Volume task to make them sound consistent.

1. Choose Tasks > Volume Correction.

2. In the Tasks panel, click the Match Volume tab.

3. Either drag files to the Files To Match list, or click the Add Files icon  below the list and navigate to files.

4. (Optional) To display average, perceived, and peak volume for each file, click the Compute icon . These statistics help you specify target values in the next step.

5. Select one of the following options:

   Match To Volume

   Matches to an average value you specify. Choose this option if no file in the group reflects the desired volume.

   Match To File

   Matches to the average volume of a specific file. Choose this option if one file reflects the target volume you want to achieve.

   The Account For Perceived Loudness option focuses analysis on midrange frequencies that the ear is most sensitive to. Keep this option selected unless frequency emphasis varies greatly in a file (for example, midrange frequencies are pronounced in a short passage, but bass frequencies are elsewhere).

   Match To Peak Volume

   Matches to a peak value you specify. Because this option retains dynamic range, it’s a good choice for files you plan to process further, or for highly dynamic audio like classical music.

6. Click Match Volume.

7. Review the reported volume change in each file, and click Close.
