Brusfri is an effective audio noise reducer designed with a simple and user-friendly interface. It excels at cleaning up noisy audio recordings while ensuring sound quality retention. Unlike many other noise reducers on the market, Brusfri avoids using audio phasing, which often leads to unwanted side effects. Instead, it utilizes multiple fine-tuned gates to effectively silence unwanted noise.

You can also use Brusfri as an AUv3 plug-in in compatible hosts, such as GarageBand. This flexibility allows for creative audio editing possibilities.

Brusfri is great for various sound conditions. It handles guitar amp noise, vintage gear noise, pre-amp boosts, iPhone and iPad mic hiss, room reverb removal, fan noise suppression, background ambiance control, and even mains hum and electric hum filtering with ease.

Using Brusfri is straightforward. To start, press the “Learn” button while playing a few seconds of isolated noise. This will create a profile for noise that Brusfri can use for reduction. This simple process might be all you need to do to clean up your audio.

You can use Brusfri in two ways: standalone or as an AUv3 plug-in. In standalone usage, import your audio by extracting it from a video, using iTunes audio import, or through the “Open In…” option from any app that can export audio. Once imported, press and hold the Learn button (which looks like an ear) while the unwanted noise plays. It is important that the ear only receives isolated noise. When you release the Learn button, Brusfri will start reducing the noise.

If you choose to use Brusfri as an AUv3 plug-in, simply open it in any compatible host. Find a segment in your recording that contains only noise and play it. Then, tap and hold the “LEARN” button for just a moment. On releasing the button, Brusfri will begin its noise reduction process.

Brusfri offers several noise reduction parameters you can adjust to get the desired effect. The Attack Time settings, Threshold adjustment, and Release Time control help you decide how quickly and effectively the noise reduction is applied. The Threshold setting basically determines how much noise will be removed, with lower values allowing for greater noise reduction.

The Lookahead feature enhances the smoothing of transient processing. The Edge control allows you to manage how aggressively the reduction is applied, resulting in a smoother end result when using lower values. Other features include HPF, which reduces low frequencies, high-frequency compensation that boosts higher frequencies, and the ability to mix between the dry and noise-reduced signal for a balanced output.

Keep in mind that Brusfri is a CPU intensive application. For optimal performance, it is recommended to use devices like the iPhone 6 or iPad AIR 2 or better. When used as an AUv3 plug-in, it is a good idea to consider freezing tracks or bouncing tracks to reduce CPU usage.

Overall, Brusfri is an excellent choice for anyone looking to effectively reduce audio noise in a variety of recording situations, without compromising sound quality. Whether you're dealing with noisy recordings from vintage equipment, a guitar amp, or background noises, Brusfri provides the tools you need to achieve clear, professional audio.
