About

apeDelay

This audio effect app transforms sound by converting it to the frequency domain for manipulation, then back to the time domain. It offers advanced spectral effects like blur, granulation, and filtering, with extensive control over delay lines and feedback.

Highlights
  • Spectral delay with up to 2048 lines
  • STFT analysis/re-synthesis
  • Spectral Blur, Granulate, Decimator, Freeze
  • Brick-wall filters
  • AudioUnit V3 (FX) and Inter-App Audio (FX) support
  • Audiobus (Full) and Ableton Link integration
  • Built-in Stereo Sampler

apeDelay - spectral Delay implements up to 2048 delay lines with feedback or up to 2048 Brick-wall filters. The algorithm is based on the STFT (i.e. Short Time Fourier Transform) analysis/re-synthesis. The audio signal is converted in abstract ‘Frequency Domain’, where is manipulated and transformed back again in ‘Time Domain’. You can draw the Time and Feedback shapes for both stereo channels. This is achieved from the multi sliders, who provide a great tool to manage the huge numbers of parameters. You can also benefit of more advanced spectral manipulations like the Spectral Blur, Granulate, Bins Decimator, Noise Gate, Spectral Freeze and Brick-wall filters. + AudioUnit V3 (FX) + Inter-App Audio (FX) + Audiobus (Full) + Ableton Link + Audio Interface support + Microphone input + Built In Stereo Sampler with varispeed and scrubbing + Control Manager LFO for all the Parameters + Midibus, Virtual Midi and Network: 14 bit NRPN controllers + Sample Manager, sharing common audio files via iTunes, Dropbox and AudioCopy + Snapshots Presets Morphing Pad + Post Fx: Stereo Delay, Amazing ClassicVerb Low/Hi Shelving and Dynamic Processor + etc...

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.
