Pro Audio Tips
How to Get the Absolute Best Studio Quality
Keep Intensity at 85%–90%
100% noise removal creates an ultra-dry acoustic environment. Setting the intensity slider to 85%–90% leaves a tiny touch of natural room atmosphere while completely eliminating unwanted background buzz.
Fixing Hollow Bedroom or Office Echo
If your voice sounds like it was recorded in an empty room, make sure Remove Room Echo (De-Verb) is checked. It suppresses late reflections so your voice sounds up-close and personal.
Adding Shure SM7B Proximity Warmth
Phone and laptop microphones lack low-end chest tone. Enabling Studio Mic Warmth simulates speaking 2 inches away from a $400 radio broadcast dynamic microphone.

Technology
In-Browser Neural Speech Isolation
Unlike basic noise gates that abruptly cut off your voice, this tool runs a real Recurrent Neural Network (RNNoise WebAssembly) directly in your browser. Trained on thousands of hours of clean speech and real-world noise, it identifies human vocal cord vibrations and separates them from background noise.
Combined with our Ephraim-Malah Decision-Directed Wiener Filter and Consonant Shield, high-frequency consonants ("s", "t", "f", "k") are guarded so your voice never sounds muffled or underwater.
Running 100% inside your browser via WebAssembly, your audio never touches an external server. It is completely private, unmetered, and instantaneous.
