LFOH! is an augmented, stunning (as the name suggests!), LFO which enhances the possibilities of the classic cycling envelope by adding control over a set of advanced and unique features. LFOH! is a single oscillator LFO and has a set of continuously morphable and selectable waveforms that represents the core of its modulation signal. Apart from the classic frequency and phase parameters (which make it capable of all of the classic modulation stuff), the waveform can also be shaped by swinging its cycles, bending its curve, squeezing portions of oscillation in the same period of time, scaled and transformed while exceeding its boundaries. An additional Sample and Hold circuit provides quantization for the resulting signal. A tool you already know, with the most advanced features: simple and powerful. LFOH! is both an audio processor and a MIDI modulator: while is capable to send its modulation signal out as MIDI CC (according to the MIDI routing flexibility of the app that hosts it), it can also modulate the amplitude of incoming audio. *** Please note: LFOH! is an Audio Unit extension (AUv3) – it only works in an AUv3 host app like AUM, Drambo, Cubasis, etc... ***

"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.)
