Why increase your AAC volume?

AAC (Advanced Audio Coding) files are widely used across Apple devices and streaming platforms, so there's a good chance you've got a few sitting on your phone or computer right now. If any of them sound too quiet, you'll know the frustration of constantly reaching for the volume slider, only to find it's already at maximum. This is a common issue with AAC files downloaded from different sources, where recording levels can vary widely depending on the original equipment and environment.

Zamzar's volume increase tool lets you make your AAC files louder without needing to install audio editing software. You upload your AAC file, pick your preferred volume boost (125%, 150%, 200%, or 300%), and download the louder version. It's particularly useful if you're putting together a playlist where some tracks are noticeably quieter than others, or if you've received a voice recording from a colleague that's difficult to hear clearly. Podcasters who record interviews remotely often run into this too, where one participant's audio comes through much softer than the other. And if you've got old AAC recordings from a phone or dictaphone, boosting the volume can make them far easier to listen back to.
