Is fragment of your voice recording too quiet? Do your audio files have different volume levels? Smart Gain can both normalize the volume level of all audio files and amplify a quietly recorded track or its fragment.
You can be sure that the file will be played at the same volume everywhere, not only in iTunes. By normalizing your files without converting them, Smart Gain allows you to retain the original quality of all your audio files.
Smart Gain automatically selects the best volume level for each file, causing all files to be played back at the same volume level. Manual adjustment of amplification offers a way to amplify quietly recorded tracks, such as a voice recording, to an appropriate level. Changes made to the amplification level are immediately reflected in the file waveform, enabling you to achieve the best result effortlessly.
You have the option to change the volume level of an entire file or its fragment.
