Brusfri vs lo

Brusfri* is a highly advanced audio noise reducer, packed into a simple and straight-forward interface. It is very well suited for cleaning up noisy audio recordings, while retaining sound quality. Unlike many other noise reducers on the market, Brusfri doesn't mess with audio phasing to suppress noise (a technique that often comes with audible side effects). Instead, multiple fine-tuned gates are used to silence unwanted noise. Brusfri can also be used as a AUv3 plug-in in compatible hosts, for example in GarageBand. *Brusfri means "Noise free" in Swedish. Here are some examples of sound conditions that Brusfri handles well: * Guitar amp * Noisy vintage gear * Boosted pre-amp * iPhone/iPad and external mic hiss * Room reverb removal * Fan noise * Background ambiance * Mains hum / Electric hum Usage In short, press “Learn” during a couple of seconds of isolated noise to create a "profile" for noise. This may be all you need to do. Brusfri can be used in two ways, either standalone or as a AUv3 plug-in. Standalone Import the audio, either by extracting audio from a video, by importing from iTunes, or by using the “Open In…” option in any other app that can export audio. Press and hold the Learn button (the ear) while playing unwanted noise. (It’s important that the Ear is only fed with isolated noise). When Learn is released, Brusfri will start reducing noise. AUv3 plug-in Open Brusfri in any AUv3 compatible host. Find a region in the recording that only contains noise and play it. Tap and hold the “LEARN” button for a short while (a second will be enough). When the LEARN button is released, Brusfri will start reducing noise. There are a bunch of parameters available that affect the noise reduction algorithm: ATK / THRS / REL (Attack Time / Threshold / Release Time) Threshold - basically determines how much noise to be removed. A lower value means more reduction. Attack and Release sets the time it will take for the reducer to start working. LOOKAHEAD Makes transient processing a bit smoother. EDGE Controls the reduction aggressivity. A lower value gives a smoother reduction. HPF Reduces low frequencies. HIGH Compensates high frequencies by boosting them. MIX Mixes between dry and noise reduced signal. NOTE! Brusfri is CPU intensive and iPhone 6 / iPad AIR 2 or better is recommended. When used as an AUv3 plug-in, we highly recommend freezing/bouncing tracks to reduce CPU usage.

"LO‑FI‑AF is a very capable lo‑fi toolkit capable of surgically targeted destruction and it could easily find applications in just about any musical genre" -SoundOnSound Unfiltered Audio's lo-fi-af is now available on iOS as a Standalone app or AUv3 plugin! lo-fi-af takes your sound on a journey of artifacts and noise throughout recorded history, from tape warbles and vinyl noise to MP3 chirps and cell phone speaker chatter. lo-fi-af's many sections and versatile algorithms can place your sound in a different decade, or give it a thoroughly modern spin through compound processing. The first section is a convolution reverb preloaded with impulse responses from broken microphones, toy speakers, cell phones, and more. With this section alone, you can place your sound into an entirely different space. The Spectral section then splits your sound into thousands of frequencies before reconstructing it with a twist. Here you can reproduce the sound of a pirated MP3 or pitch shift your signal with clean perfection. Your signal then takes a trip through the digital section. All sorts of hazards are present here, from a skipping CD stutter effect to a multimode bitcrusher. Finally, the rich, colorful analog section adds that vibe that you crave. A maximizer, a tape saturator, a noise generator, an analog-style filter, a pitch warbler, and a radio demodulator all work together in harmony to toss your sound into the past. But wait! That's only one possible signal chain. The Convolution, Spectral, Digital, and Analog sections can be completely rearranged in any order. Dozens of presets will get your started on your sound warping adventure. As an AUv3 plugin, lo-fi-af has been tested to work perfectly with Garageband, Drambo, AUM, Cubasis, Beatmaker, Nanostudio, apeMatrix, Loopy Pro, and more! Additionally, with its clear layout and smart resizing, lo-fi-af can be used on tablets and phones with ease. (Note for Drambo users: Drambo does not yet have automatic Plugin Delay Compensation for managing plugins with latency. As a result, tracks with lo-fi-af will not line up properly with other tracks. An upcoming patch for Drambo will add this feature in.)
