Phawuo is an experimental monophonic virtual-analog synth with "dirty" oscillators. Good for bass sound and effects. New in version 3: - OSC support - AUv3 - Available for macOS (as a separate version); presets can be shared across devices It features: - Two special oscillators. Each one has two modes playing more rough (though antialiased waveforms with inharmonicity in higher pitches) or "cheezy" sound. Plays sawtooth / square waveform and is capable of pulse width modulation. - distortion and feedback ring modulation for each oscillator - 24 dB/octave state-variable filter (LP-BP-HP) - two ADSR envelopes for amplitude and filter - LFO to modulate the frequency and pulse width of oscillators' waveforms - Effects section: two channels of delay + frequency shifter with feedback with some flexible routing. Also includes basic reverb - Precise parameter editing: tap and hold finger on the slider. - Audiobus support. Now you can stream live audio directly to other Audiobus-compatible apps! See http://audiob.us for more information. - Inter-App Audio support - Background audio support: enabled when connected to Audiobus and user switchable otherwise. - CoreMIDI support - virtual midi input

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.
