Volume leveling

Levels

“Off”

The recording sounds as it is. Selected by default.

“Light”

Adds no more than 6 dB.

“Medium”

No more than 12 dB.

“Strong”

No more than 18 dB.

How it works

• The loudness of each file is measured once, in the background, across the whole file. Until a file is measured, it plays without a boost.
• A quiet file is raised as a whole by one amount — to the normal level of speech, but no higher than the level’s limit.
• The sound does not clip: a file is raised no higher than its loudest moment allows. A recording with sharp peaks may not be raised at all.
• A file that already sounds loud is left as it is.

Worth knowing

• The recording’s noise rises along with the voice: hiss, hum, music under the voice.
• Volume is not evened out within a file: a quiet phrase next to a loud one stays quieter.
• Turned processing on, or off completely, while a book is playing? The change takes effect at the next pause. A different level is applied by the player at once.
• Without Pro the row is locked; a level chosen earlier is kept but does not apply.

Tip

Keep a noisy recording on “Light”: on “Strong” the noise grows by as much as the voice. Processing uses more battery.
