Stellarvox - Ambient reverberation space designer

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). Stellarvox works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, with supports Audiobus host app. On MacOS, Stellarvox can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option) and audio unit parameters. Stellarvox has a built-in detailed description of all parameters also available as PDF file on the application site.

Stellarvox - ready to release

Today I finished working on another application. Stellarvox is an experiment in which I tried to expand the algorithm of the space impulse response (IR) generator, supplementing it with a set of various single pulses (very short IR), which are essentially filters in the impulse response sample for convolution reverb and form the timbre of the reverberation space. The result is very interesting virtual spaces with different sound characteristics.

To experiment with the sound of space and in order to make it somehow more unusual and unrealistic, I made it possible to add an additional signal with different frequency spectra to the generated IR sample and the ability to process this signal with various filters in which the frequency changes from the beginning to the end of the signal (length which corresponds to the reverberation time). This signal gives a very peculiar tail of reflections that are not tied to the space model itself, but are audibly felt as its continuation.

Well, in order to make this application completely experimental, I added the so-called "Schroeder reverb" algorithm, which is built on the principle of a series of delays with all-pass filters. This algorithm is good because it gives a fairly blurry tail of reflections for almost any source signal. Combined with the convolution reverb, it adds blur to the reflections tail and makes the reverberation space more saturated and vibrant, although even less reality. Also, when the inverted convolution sample mode is selected, the algorithmic reverb may produce early reflections before the convolution reverb begins to sound.

The goal of this project was not to make another virtual room simulator, but to create a generator of unusual, deep and rich spaces with a long reverberation time and a long reflections tail. The result is an interesting and quite unique application that is very well suited for adding spatial and background to sequences and arpeggios of various synths, including those with a predominant low-frequency spectrum in electronic music. But even more interesting is the sound of individual notes and sounds in which all transitions in space are clearly audible. This is great for ambient and experimental projects.

NoInputMixer for iOS and macOS Opens New Frontiers in Synthesis

Paul Williams - No input mixing is a boutique synthesis technique used by sound designers usually armed with only a mixer and some cables. It offers an exploratory approach focused on the creative control of noise and feedback. If interested in new frontiers of sonic exploration, this is a sound design area worthy of your notice.

Simply experimenting remains the right approach to get the most out of the app. There are no mistakes when using NoInputMixer! For example, during one of my first sessions with the app, I somehow stumbled upon this interesting rhythm. Working in AUM, I simply hit record with the following result.
