Alien Box is a completely new kind of audio effect that you have never heard before. It makes the sound big and slightly increases the sustain while adding gentle vibes to it. The vibes are LFO modulated and the effect is using very complex resonator system inside. It is modulation effect and you can compare it to flanger, phaser or chorus but it is not like any of them… The app is an Audio Unit Effect AUV3 and can be used inside GarageBand or other AU host apps as an effect plug-in. Alien Box can also run as a stand alone app adding effect to the audio input so you can play your guitar, bass or synth directly three the app if you have the connector to do so. Alien Box controls: - Gain - you can use it increase the gain and sustain - Vibe - main tone and background vibes balance - Depth - controls the modulations depth - Reverb - adds reverb to the background vibes

Pruina freezes sound. Tap once and Pruina captures the spectrum of whatever is playing, a chord, a vocal, a whole mix, and holds it as an endless, gently evolving drone that never decays. Then shape it into rising shimmer clouds, breathy air, crystalline bells, or a huge reverberant wash. Under the hood it runs a real spectral analysis of your audio and, the instant you freeze, takes a snapshot and resynthesizes it with slowly drifting phase. Instead of fading away, the sound sustains forever and breathes, like a pad you never have to hold down. THREE MODES, ONE ENGINE Freeze: tap to capture and hold the spectrum indefinitely. Smear: continuously blur the spectrum into a soft, washing texture. Shimmer: pitched, regenerating layers that rise endlessly. SHIMMER THAT RISES Choose an interval (octave, fifth, octave plus fifth, or two octaves) and turn up Regen to feed the shimmer back on itself, building infinite cascading clouds. BUILD CHORDS BY EAR Turn on Layer and every freeze adds to what is already held. Stack captures into evolving chords and pads, live, one tap at a time. SCULPT THE SOUND Blur: smear the spectrum across frequency to morph a pitched freeze into breath and air. Sparkle: gate down to the spectral peaks for glassy, bell-like tones. Warp: stretch the timbre. Motion: slow drift and breathing that keep a frozen pad alive. Tone: low cut, high cut, and tilt. SPACE A lush, modulated reverb (Reverb, Size, Damp) wraps everything in a wide, dimensional tail, from an intimate room to a cathedral that rings for minutes. Stereo Spread and Width open it up. 16 READY-TO-PLAY PRESETS Infinite Cathedral, Rising Aurora, Supermassive, Glass Bells, Crystalline, Frozen Choir, Ghost Vox, Vapor Trails, Nebula, Granular Dust, Shimmer Wash, Dark Matter, Sub Bloom, Slow Tide, Chord Builder, and Default. Browse them with the header arrows, tweak anything, and save your own. PLUGIN AND STANDALONE Full AUv3 audio effect for GarageBand, AUM, Logic, and any AUv3 host, with host presets, parameter automation, and reported latency so your project stays in sync. Runs on iPhone, iPad, and Mac. Standalone mode includes a built-in demo pad, live microphone input, and song import with export of the processed result.
