Wave Arts MR Hum

Wave Arts MR Hum - Audio Restoration Plug-in | Professional Hum and Buzz Elimination Tool

Wave Arts MR Hum is a comprehensive restoration solution designed for audio post-production and music creation, seamlessly integrating Hum Removal, Buzz Removal, Brickwall Filtering, and high-resolution spectrum analysis functions into a single plugin. For recording engineers, it is an ideal choice for addressing ground loop issues, power interference, and various low-frequency noise. With this audio restoration plugin, users can easily purify recording quality and restore the purest essence of sound.

The core advantage of this software lies in its highly flexible parameter settings and visual feedback. Unlike general noise reduction tools, MR Hum allows users to perform precise buzz elimination processing for specific fundamental frequencies and their harmonics. Whether it's standard 50Hz or 60Hz power noise, or frequency shifts caused by speed differences in analog tape transcription equipment, MR Hum provides a continuously adjustable frequency range (20Hz to 200Hz) to handle them. Combined with a powerful spectrum analyzer, users can intuitively see problematic frequencies, ensuring that original audio details are preserved while removing noise.

Furthermore, MR Hum is specially equipped with an independent Buzz processor, specifically designed to tackle complex interference signals that span the entire audible spectrum. Traditional methods might require hundreds of filters to solve such problems, whereas MR Hum employs high-performance algorithms to effectively resolve harsh noise caused by motors, dimmers, or other electronic interference sources. For professionals seeking ultimate sound quality, this is an indispensable noise reduction and removal tool that significantly enhances the professionalism of the final product.

Core Advantages and Application Scenarios

Precise Hum Elimination Technology
The Hum elimination section of MR Hum utilizes a set of Notch Filters, which are arranged at multiples of the fundamental frequency. Users can select the fundamental frequency (typically 60 Hz or 50 Hz) and set the number of harmonics to be eliminated (up to 10) as well as the width of the notch. This feature is particularly effective for eliminating low-frequency hum introduced by power lines without causing unnecessary coloration to other frequency bands.

High-Performance Buzz Processing Algorithm
Buzz is a periodic signal whose frequency harmonics span the entire audible spectrum, and processing it with traditional notch filters would be extremely resource-intensive. MR Hum features an independent Buzz processor that uses a more efficient algorithm to handle this type of full-spectrum interference. This is crucial for eliminating harsh noise caused by motor operation, light dimmers, or other complex electronic devices.

Adaptive Speed and Analog Recording Restoration
While standard power frequencies are 50 or 60 Hz, when processing analog tapes, if the playback equipment differs from the recording equipment, the hum frequency may change. MR Hum allows users to continuously adjust the fundamental frequency between 20 and 200 Hz, meaning that even old recordings with frequency shifts can be precisely fine-tuned to find the exact interference point for restoration.

Visual Spectrum Monitoring and Auditioning Function
The built-in high-resolution spectrum display allows users to clearly observe the frequency location of hum and the required number of harmonics at a glance. The display can be switched between pre-processing (input signal) or post-processing (output signal) for easy comparison of effects. Additionally, the Monitor function allows users to listen only to the eliminated signal, which is an extremely useful aid when setting parameters, ensuring that useful audio content is not accidentally removed.
