WOV
This audio effect plugin transforms sounds into a wide range of textures, from tremolo to glitchy stutters. It offers deep customization of rate, depth, and waveform, with an eight-step sequencer for accents. Requires an AUv3 host app to function.

WOV for iOS is an AUv3 effect for making a wide range of textures out of your sounds – from familiar tremolo waves to glitchy stutters and everything in between. WOV lands on iOS with an injection of inspiring presets by Richard Devine and Stèv! *** Please note: WOV is an Audio Unit extension (AUv3) – it only works in an AUv3 host app like Garageband, AUM, Cubasis, Modstep, Beatmaker 3, etc... *** HOW IT WORKS / DESCRIPTION The Rate Section This section determines the rate or speed at which WOV operates. Rate can either be assigned in Hz, or in fractions of a beat in sync with a hosting app – to switch between Hz and sync modes, use the switches at the bottom center of WOV. It’s easy to set up a static rate for WOV and leave things at that – but WOV has much more to offer! To the right of the Rate control, the bipolar Response knob sets the sensitivity with which WOV’s rate will either slow down or speed up depending on the volume of the incoming signal. The bipolar Variation control further introduces randomized amounts of variation to the rate – at its extremes going as far half the rate (knob to the far left) or twice the rate (knob to the far right). The Depth Section Depth sets the amount of modulation over the dry signal – to the left and it’s more subtle, all the way to the right and WOV will act as a repeating gate. Silence introduces more randomness to the plugin, increasing the likelihood that the amplitude will be zero for some cycles. The Waveform Section The waveform of a tremolo effect is essentially its repeating envelope. Classic tremolo effects offer stock waves – WOV, being a K-Devices product, is much more customizable! The Wave knob morphs between a quasi-sine shape (far left) and a slightly rounded-off square shape (far right). Peak acts as a kind of attack control for the waveform – far left for a sharp attack, or far right to reach the peak more gradually. Finally, the Warp knob allows you to either squeeze or expand the waveform, affecting the length of each sound. When the Wave control is set to a full square, Warp acts as a duty cycle/pulsewidth control. The Accents Multislider The eight-step sequencer uses a multislider to set the relative accent value for each beat of the rate. The slider adjusts between two and eight steps in length, and a button offsets the accents going to the right channel one step over from the left (note that this requires Stereo to be enabled). — Get Wide WOV can either preserve the stereo placement of its input signal, or it can add stereo offset to the output signal. Enabling the Stereo switch directly affects the Response, Silence, and Sequencer for a wider sound. Go By Feel As part of encouraging more musical and creative applications of WOV, in addition to using symbols for controls, the controls in WOV do not have individual readouts. We encourage you to let your ears determine the right knob positions whenever you can! If you’d like a precise readout, however, you can see/edit it by clicking on any parameter and looking in the upper-right corner of WOV. Icons By default, all labels are graphical – for text labels, click the symbols/text label switch in the lower-right had corner.

"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.)
