( THIS IS AN AUDIOUNIT. AudioUnits are app extensions, requiring any audio host application to perform. ) Use the same AudioUnits across all modern Apple devices, including the iPhone and the Mac (Apple Silicon). Native MacOS apps like GarageBand, MainStage 3 and Logic Pro X are fully supported. Any 3rd-party AUv3 supporting host should be able to host the plugin too. The JAX ESSENTIAL SERIES Phaser is a multi stage phaser modulation effect that uses multiple allpass filters, to produce all kinds of the famous phaser effect. A low frequency oscillator modulates depth and speed of the filter modulation on both stereo channels for various living and moving sound nuances. Make static sounding voices more interesting or create sweaping special effects. You may share the presets for this effect across all your supported devices. Around 200 factory presets are included, you can make and export/import your own. The complete manual is included and can be previewed on our support website: https://audio.digitster.com For advanced usage (i.e. mastering and exciting), we recommend to select the phaser from our SELECTIVE RANGE SERIES, which allows to limit the frequency range for processing. This build is truly 'universal', meaning, the audio unit is available for: - iOS (all actual iPhones) - iPadOS (all actual iPads) - macOS (Apple Silicon) - visionOS (Apple Vision Pro) Requirements: MacOS 11.0++ iOS 14.0++ Behaviour on all devices is identical. The parametric interface is resizeble and adopts to any screen size and orientation. This especially applies to Logic Pro X and all hosts with adjustable window sizes on all platforms.

Hybrid reverb with an artificial space designer, combining it with algorithmic reflections tail processing, is ideal to creating immersive ambience of deep spaces, lush atmospheric textures or stunning whispering backgrounds in your ambient, electronic, experimental and sound design projects. Unlike traditional algorithmic reverbs, Stellarvox constructs a complex model of a vast resonant sound spaces with choice of geometry, dimensions and tonal structure of the space, along with a unique feature that dynamically change the timbre of reflections over the reverberation time. The second algorithmic reverb allows you to prolong and blur reflections, adding extra dimensions to the sound space. Easy-to-use controls on a single screen, along with optimally designed parameters that always give great results, make insignificant the peculiarity of that kind of reverbs, when the model creates with a little delay after changing it. Factory presets and the random feature will give you a starting point of inspiration and allow you to get a quick result where you need just to slightly tweak the parameters to align with your idea. This application is great for ambient projects, it can create mesmerizing atmosphere from single infrequent sounds of various instruments, or giving a beautiful and deep backgrounds to sharp sequences in electronics, as well as for any experimental projects that require unusual, deep and rich sound ambience. Stellarvox is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later).
