Compression, loudness-normalization, and noise-reduction can be daunting in nearly any audio-editing app. But Auphonic makes it as easy as it could be, with even some extra control if you need more versatility!

Auphonic is available in two editions: a web version with monthly free and paid-subscription allotments of audio-processing hours, and a one-time-purchase Desktop Leveler app for Windows and macOS. The web version gets the latest technologies first, and is actually slightly superior, but the Desktop Leveler is faster and you only pay once for unlimited use.
