Essential Information About the "MR Hum" Software
- Removes hum and buzz using harmonic notch filters (up to 10) and a dedicated buzz algorithm.
- Precise adjustment of frequencies from 20 to 200 Hz, adjustable notch width, monitoring of the removed signal.
- Brickwall filters to effectively eliminate rumble (very low frequencies) and hiss (very high frequencies).
- High-resolution spectral analysis for pre- or post-processing, zero-latency workflow up to 192 kHz.
What MR Hum Is For
Designed for audio restoration, MR Hum cleans recordings affected by 50/60 Hz mains hum, motor buzz, or interference in just a few steps. Ideal for post-production, podcasts, interviews, dubbing, sound design, and archiving, it isolates the problematic component without degrading timbre or dynamics, ensuring clear dialogue and clean ambiances.
Main Features
Hum removal with notch filters
Select the fundamental frequency (50/60 Hz or any value from 20 to 200 Hz) and the number of harmonics to attenuate, up to 10. The notch widths are adjustable to precisely target the noise while preserving music and voice. Presets speed up the setup process.
Dedicated broadband buzz algorithm
Periodic buzzing, rich in harmonics across the spectrum, is processed by a specific processor far more efficient than hundreds of notch filters. It adapts to sources originating from mains or mechanical noise, with free selection of the fundamental frequency from 20 to 200 Hz.
Analysis, monitoring, and brickwall filters
The high-resolution spectrum analyzer clearly visualizes interference peaks before and after processing. The "Monitor" function allows listening only to the removed signal for precise adjustment. Brickwall high-pass/low-pass filters eliminate stubborn very low frequencies (kick drum, rumble) or very high frequencies (hiss).
