Product Overview: Klevgrand Brusfri
Introduction
Klevgrand Brusfri, which translates to “Noise free” in Swedish, is a highly advanced audio noise reducer designed to clean up noisy audio recordings while preserving sound quality. Developed by Klevgränd Produkter, Brusfri offers a simple and straightforward interface that makes it accessible to a wide range of users, from musicians and voiceover artists to film and podcast producers.
Key Features
Noise Reduction Methodology
Unlike many other noise reduction tools that use audio phasing techniques, which can introduce audible side effects, Brusfri employs multiple fine-tuned gates to silence unwanted noise. This approach ensures that the desired sound remains untouched, avoiding common artifacts like squishy or phase-altered audio.
User Interface and Controls
Brusfri features an intuitive and unique user interface that simplifies the noise reduction process. Key controls include:
- Learn Button: Allows users to feed audio data to create a noise profile by simply pushing and holding the button. This is often the only step needed for effective noise reduction.
- Attack / Threshold / Release: These parameters control the internal expanders, enabling precise adjustment of the noise reduction settings.
- Tonality: This feature allows for tweaking the noise profile, especially in cases where heavy noise is present, to ensure the best possible results.
Technical Specifications
Brusfri is compatible with a variety of platforms and formats, including:
- AU, VST-2, VST-3, and AAX for Windows and macOS
- AUv3 for iOS devices
- Optimized for macOS 10.10 or later, including the M1 processor, and Windows 7 SP1 or later.
Functionality
Brusfri is versatile and can be applied to various types of audio recordings, such as:
- Voiceover tracks
- Instrument tracks
- Full mixes
It is particularly effective in eliminating broadband nuisances like fan noise, power hum, and ambient noise, making it a valuable tool for maintaining high audio quality in different production environments.
Summary
Klevgrand Brusfri is an advanced yet user-friendly noise reduction tool that stands out for its innovative use of fine-tuned gates and its ability to retain the original sound quality of the audio. Its simple interface, combined with its robust functionality, makes it an essential asset for anyone dealing with noisy audio recordings.
