## What is DubFocus?

DubFocus helps you stay focused in noisy environments by making distracting speech harder to follow and masking it with a steady, immersive soundscapes.

Researches on the irrelevant speech effect shows that background voices can disrupt memory, reading, and other verbal-focus tasks because speech is automatically processed by the brain, even when you are trying not to listen. Studies also suggest that intelligible speech is especially distracting in offices and study environments, while acoustic masking can reduce speech intelligibility and improve the conditions for cognitive work. Noise-cancelling headphones can make an environment feel quieter, but ANC alone does not always remove the cognitive disruption caused by residual speech. DubFocus goes further by using real-time acoustic masking: it listens to incoming sound and layers compatible masking textures over the speech patterns and frequencies that make voices easy to follow. The result is not just “less noise,” but a more predictable auditory environment where distracting voices become harder for the brain to decode, helping you stay focused while reading, writing, coding, studying, or doing deep work.

DubFocus generates sound in real time from your microphone input and your device CPU. It blends input with customizable sound layers, binaural elements, and DSP effects. The result is a predictable auditory environment that helps you stay in focus, filter distractions, and remain in flow longer.

Features:
• Immersive low-distraction soundscapes for deep focus
• Fully customizable real-time sound engine
• Acoustic masking to reduce speech intelligibility
• Binaural layers for the brain activation
• Designed for reading, writing, coding, study, mediations

For the best experience, use headphones.
