apeFilter is a sophisticated Equaliser, the DSP is based on the Biquad/Cascade filters, very fast! The graphical interaction provides a great tool to design an extremely precise and smooth frequency response by directly manipulating up to 36 Peaks Filters. The Spectral Grid compilers increase the complexity and coherence between the filters bandwidth space. You can create your pitch space by the way of four different criteria of construction by determining a pitches grid: Fibonacci, Harmonic, Geometric and Scalar. Use apeFilter for sculpt your sound through the embedded sampler or LIve from Audiobus or Inter-Audio-App Input. Among the FX chain, an amazing ClassicVerb is available. + AudioUnit V3 (FX) + Inter-App Audio (FX) + Audiobus (Full) + Ableton Link + Audio Interface support + Microphone input + 72 Peak Filters for Spectral Grid Compilers + 4 Spectral Grid Compilers: Fibonacci, Harmonic, Geometric and Scalar + 6 Common Filters: Lowpass, Hipass, Bandpass, Notch, Lowshelf, Hishelf + MIDI Note On/Off messages, for playing Filters Frequency and Filters Peaks Gain + Audiobus and Inter-App Audio support (sender and FX) + Built In Stereo Sampler with varispeed + Control Manager LFO for Parameters + Midibus, Virtual Midi and Network: 14 bit NRPN controllers + File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy + Snapshot Presets Morphing Pad + Post Fx Chain: Stereo Delay, Amazing ClassicVerb and Dynamic compressor/expander

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.
