Transform Phone Recordings into Studio-Quality Conversations

Ever recorded a chat on your phone across a reverberant room? DeReverb AI’s AI-driven noise and reverberation filter makes your voice sound clear and focused—as if you’re holding a professional mic. Trained exclusively on speech, it’s perfect for podcasts, narrations, interviews, and more.

Why Room Acoustics Matter

A reverberant room has hard, reflective surfaces—like bare walls or floors—that cause sound waves to bounce around. This creates echoes and a muddy, indistinct audio quality that can obscure speech details and tire listeners.

Reduced Clarity: Reflected sound smears words together, making speech harder to understand.
Listener Fatigue: Constant echoes force listeners to concentrate more to follow conversations.
Background Noise: Ambient sounds and reverb combine, masking voices in recordings.

DeReverb AI’s AI-driven filter tackles both reverb and background noise, delivering clear, focused audio that sounds as if you recorded with a professional microphone in a treated studio.

About This Project

Born from a machine-learning prototype, DeReverb AI is my speech-focused noise and reverberation filter, trained exclusively on conversational data so it performs well on podcasts, voiceovers, and interviews. Though it’ll live inside my GFSoftware shareware lineup soon, this lightweight freeware release lets anyone instantly polish their recordings without installing a full editing suite.

Real-time noise & reverberation filtering
Batch processing (coming soon)
Offline-only: zero uploads—your audio never leaves your computer

Current Limitations:

Fixed sample rate: 44.1 kHz
Top processed frequency: ¼ of the Nyquist frequency
May introduce subtle distortion depending on input reverb/noise
