"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.)
