OneKnob Louder Black Friday pricing takes 38% off this Waves one-knob loudness plugin, which brings it to $29.99 until Nov 26, 2026.
It raises the level of a track, bus or full mix with peak limiting, low-level compression and automatic makeup gain. One control does the work, so you get a louder result in seconds.
The maker's pitch: your mix sounds fine, but it doesn't pop next to commercial recordings in a playlist.
Waves says the plugin lifts the level without flattening the dynamics. The compression works on low-level material, the limiter catches peaks, and makeup gain is applied for you.
That means you don't gain stage the compressor by hand after setting it. Turn the knob and the output comes up with it.
It isn't only a mix-bus tool. The maker lists several jobs for it:
The maker also says it minimizes unwanted level variations on individual tracks.
Waves describes the sound as open, with natural dynamics and no harshness. The idea is that you push the level up without the squashed, brittle result heavy limiting can give.
It's aimed at musicians and songwriters who want to dial in a powerful sound fast. The maker says it distills engineering skills into a single knob.
