We've all been there. It's late, you're trying to watch the latest blockbuster, and you can't understand what the actors are saying.
The action scenes are deafening. The explosions shake the room. You dive for the remote to turn the volume down.
A second later, the actors are whispering. You have to grab the remote again and crank the volume back up, just to hear the plot.
This is the "volume rollercoaster," and it's one of the most frustrating things about watching modern movies at home.
Why Does This Happen?
Movies are mixed for theaters with powerful surround sound systems. They have a massive "dynamic range," which is the difference between the loudest possible sound (an explosion) and the quietest possible sound (a whisper).
In a theater, this is immersive. In your living room or on your MacBook, it's just annoying.
The "Old" Ways to Fix It (and Why They Fail)
For years, we've tried to find workarounds:
The Subtitle Surrender: This is the most common fix. You just give up, turn on the subtitles, and read the movie. This works, but it pulls you out of the experience. You're too busy reading to watch the beautiful cinematography.
The Volume Remote Jockey: You spend the entire movie with your hand on the volume, constantly adjusting. It's exhausting, and you're never truly immersed in the story.
The "Graphic Equalizer" Mess: You might have tried digging into a player like VLC to find the graphic equalizer. You're then faced with 10+ confusing sliders, and you're left to guess which frequencies control "voice." You can often make the sound worse—tinny, flat, and still muffled.
There has to be a better way.
The Simple, Modern Solution: Vidi's "Voice Boost"
We built Vidi with this exact frustration in mind. We wanted a simple, one-click solution that just works.
It's called Voice Boost.
Voice Boost is not just a volume knob. It's an intelligent audio filter. When you turn it on, Vidi instantly:
Identifies the specific audio frequencies of human speech.
Boosts those frequencies to make them clear and crisp.
Gently compresses the loudest sounds (like explosions and gunfire).
The result is clear, present, and perfectly audible dialogue, even at low volumes. You can set the volume once and enjoy the movie. No more rollercoaster.
Vidi's Voice Boost has three levels (Low, Medium, and High) so you can dial in the perfect amount of clarity for any movie or TV show.
It's Part of a Full Audio Suite
We didn't just stop at dialogue. Voice Boost is one part of Vidi's Immersive Audio Suite, a set of tools designed to give you the best sound experience on a Mac.
It also includes:
Cinema Effect: Get that punchy, theater-like bass and presence.
