A simple equalizer app that applies to all any app audio source and any output, be it speaker or bluetooth. Has no balance feature.
Phenomenal; simple. Mandatory/loved because bluetooth headphones are often manufacturer bass-boosted with no ability to disable it.
For reading, writing, and manipulating image, audio, video, and PDF metadata.
A simple volume icon for your taskbar's tray.

An audio player.
Straightforward, with few dependencies and a lot of audio format support.
