Adjust Match Volume settings
❖
In the Match Volume panel, click Settings to adjust the following options:
Match To
Determines how amplitude is mathematically compared:
•
Total RMS
Matches an overall loudness you specify.
•
File
Matches the overall loudness of a selected file. Choose this option if one file reflects the target volume you
want to achieve.
•
Loudness
Matches an average loudness you specify.
•
Perceived Loudness
Matches the perceived loudness level, accounting for middle frequencies that the ear is
most sensitive to. This option works well unless frequency emphasis varies greatly in a file (for example, midrange
frequencies are pronounced in a short passage, but bass frequencies are elsewhere).
•
Peak Volume
Matches a maximum amplitude you specify, normalizing the files. 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.
Use Limiting
Applies hard limiting to keep peaks from being clipped. (When you amplify audio, some samples may
extend beyond the clipping point.)
•
Lookahead Time
Specifies the number of milliseconds to attenuate audio before reaching the loudest peak.
Note:
If this value is too small, audible distortion might occur. Make sure that the value is at least 5 milliseconds.
•
Release Time
Specifies the number of milliseconds for attenuation to rebound 12 dB (roughly the amount
needed to resume normal volume after an extremely loud peak is encountered).
Note:
A setting of 200 milliseconds works well to preserve low bass frequencies. If the setting is too high, audio may
stay below normal levels for a while.

Batch process files
Batch process groups of files to quickly apply favorite processing, resample, or save to a new format. Quickly automate
common tasks like exporting to mp3 format or applying identical effects to related files.
1
In the Waveform Editor, choose Window
> Batch Process.
2
Drag files from the Files panel to the Batch Process panel. Or click the Add Files button
in the panel to browse
to files on your system.
Note:
By default, batch processing is limited to three files at a time for optimal performance. To process more files,
change the value for Maximum Number Of Concurrent File Processes in the Data preferences.
3
Click Batch Process, and set the following options:
Apply Favorite
Applies a combination of effects, fades, and amplitude adjustments. (See “
Favorites
” on page 55.)
Filename Prefix and Postfix
Help you identify batched files.
Location
Specifies the destination folder for processed files.
•
Same As Source File Location
Saves modified files in the same folder as the file’s source file.
