Hz Box is a free algorithmic soundbox emulator plugin that adds character by changing the timbral quality of any sound. The plugin can help define a sound’s place in your mix by giving it the richness and depth it needs.

Hz Box can also bring flat sounds to life with a little brightness and just the right amount of sparkle. Since we’re taking the concept of what a real-world soundbox does to sound, Hz Box can make subtle character changes or create an entirely new tonal profile.

Hz Box is available in 64-bit AU, VST 2.4, and VST 3 formats for macOS and Windows.
