Podcast productions are often affected by uneven voice levels. This makes them unpleasant to listen to, especially in noisy environments, where the ambient noise can mask the low volume parts and make them difficult to understand.
Castamatic has a program dependent automatic leveler that automatically increases audio level consistency between different parts/voices of each show, without altering original audio character.
You can find the leveler switch by tapping on the Audio Fx icon in the bottom-right corner of the player panel.
Three level meters are also displayed in the Audio Fx panel, showing the original audio level, the amount of leveling applied at every moment, and the resulting output audio level.
