The unique pitch-shifting reverb in BLEASS Shimmer makes performances dance and sing in ways you never imagined possible. Harmonics are emphasised and new tonal colours emerge as luscious washes of reverb thicken and harmonise with your performance, opening up a whole new creative dimension of spatial and ambient effects. The flexible processing architecture makes BLEASS Shimmer a highly versatile plugin overflowing with creative musical possibilities. Shape the incoming sound with the multi-mode input filter, place the two pitch-shift modules at different points in the signal chain for wildly different results, and combine them with a clean, rich reverb. An integrated ducker helps the direct signal stand out from the reverb and is perfect for rhythmic and blooming effects. This vast sonic potential is easy to tame, both live and in the studio, thanks to a clear and tactile interface designed for hands-on exploration. More than 30 included presets reveal the depth of possibilities on offer while providing great starting points for your own sound designs. From guitars and synth pads to leads, vocals and drums, BLEASS Shimmer brings exciting new dimensions to your musicianship. More information and technical specifications available on https://www.bleass.com/shimmer/ BLEASS Shimmer can be launched as an AUv3 plugin or as a standalone app. BLEASS Shimmer is also available for Windows, and macOS.

"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.)
