This audio effect is an advanced de-esser with an intuitive user interface, and works both as an AUv3 audio plugin, and as a standalone app. The uniqueness of Esspresso is that the detection frequency range isn’t coupled with the suppressors frequency range. That means you can listen to a specific frequency and compress another one, which is often what you’ll want from a professional de-esser. With a fast and accurate frequency response view, you will easily get full control over annoying S-sounds that ruin the mix. Noteworthy features: • Works both as a standalone app and as an Audio Unit Extension (AUv3) with compliant hosts • Detector sensitivity gain • Visual reduction RMS • Visual detector RMS • Suppressor can work as allpass, bandpass and highpass • Load / Save presets

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).
