About

RocketVerb

Read full description

RocketVerb is a creative algorithmic reverb for iPhone and iPad, designed to transform instruments, vocals and recordings into spaces that move, bloom and evolve. Its character was shaped through the study of public space audio, planetary recordings and astronomical data sonifications. Their spectral movement, density and texture were translated into 38 internal profiles. RocketVerb does not replay those recordings as samples or fixed impulse responses. Every reverb tail is synthesized in real time. SHAPE YOUR SPACE Use five focused controls to build the foundation of the reverb: - Pre separates the original sound from the reverb bloom. - Density moves from open reflections to smooth clouds. - Length controls the duration of the tail. - Size changes the perceived scale of the environment. - Shape moves between tight, blooming and suspended responses. MOVE THROUGH THE GALAXY The interactive Galaxy cursor modifies distance, brightness, motion, scatter and the balance between early reflections and the tail with a single two-dimensional gesture. SIX CREATIVE EFFECTS - Radiation adds energy, mass and charged texture. - Orbit introduces stereo movement and subtle pitch drift. - Filter shapes the tonal range of the processed signal. - Granular Cloud transforms audio into layered, evolving slices. - Comet Trails creates rhythmic and atmospheric delay repetitions. - Dust introduces organic noise, texture and movement. Granular Cloud and Comet Trails include interactive 8-step patterns and can process either the direct input or the reverb signal. INFINITE FREEZE Capture the current atmosphere and keep it circulating indefinitely. Release Freeze to return smoothly to the live reverb tail. 144 FACTORY PRESETS Explore eight categories covering practical mix spaces, cinematic environments, orbital motion, granular textures, dusty planetary colors and deep ambient tails. Save your own presets directly from the app. AUv3 AND STANDALONE Use RocketVerb as an AUv3 effect in compatible hosts such as GarageBand, Logic Pro for iPad, AUM and Cubasis, or run it as a standalone app with a microphone or connected audio interface. SOURCE DISCLOSURE Some public NASA audio and sonification material was used as source material during development. This factual disclosure does not imply NASA review, approval, sponsorship, endorsement or affiliation. RocketVerb is an independent ZAK Sound product. The original recordings are not replayed by the app.

TURN A NOTE INTO SOMEWHERE ELSE. VESPER is a stereo delay and reverb playground for iPhone and iPad. Start with a tight rhythmic echo, stretch it into a suspended room, then pull the sound apart with your fingertips. Use it as a standalone effect or load its AUv3 extension in a compatible music app. TOUCH THE SOUND Open Wave Field and the pedal unfolds into three interactive surfaces: TIME, SPACE and FRACTURE. Drag to reshape connected groups of parameters, from repeat spacing and feedback to room size, pitch and memory. Depth controls add another dimension. Keep the transformation, restore your starting point, or save a new preset. TWO ENGINES. MANY DIRECTIONS. Combine six echo arrangements with eight space voices. Explore pitch-shifted trails, reverse textures, stereo cross-feedback and moving diffusion. Choose how the engines feed each other, place processors across ten insert slots, and move between host-synced subdivisions and free timing. SOUNDS THAT KEEP MOVING Six modulation sources, a sixteen-step sequence and twelve modulation routes bring motion to your sound. The BECOME control performs a dedicated transformation in each factory preset. Freeze a texture, ride the mix, or use Memory Glass to introduce pitched fragments of recent audio. 100 PLACES TO START The included factory collection ranges from Impossible Rooms and Clockwork & Trouble to fractured rhythms, altered gravity and long-form textures. Search sounds by name, collection or tags, mark favourites, compare A/B states, and import or export your own presets. BUILD A PHRASE Capture up to 20 seconds of stereo audio in the iOS looper. Add up to three layers, adjust their levels, reverse playback or switch to half speed. Choose where the loop records and returns in the signal path. MADE TO PLAY A detailed pedal interface brings the main sound controls within reach, with a multifunction display for deeper editing. Dry/Wet and output makeup gain let you place the effect around your source. Wave Field turns sound design into a performance gesture. INCLUDED • Standalone app and AUv3 audio effect for iPhone and iPad • Stereo delay and reverb engines with flexible routing • Interactive TIME, SPACE and FRACTURE surfaces • 100 factory presets with individual BECOME transformations • Modulation, step sequencing, pitch and memory processing • Three-layer stereo looper • Preset search, favourites, A/B comparison and import/export Requires iOS/iPadOS 16 or later. AUv3 operation requires a compatible host app, available separately. Standalone live input requires microphone permission; headphones or an audio interface are recommended. An internal AUDITION phrase lets you explore sounds without connecting an instrument. Loop recordings are session-only and are not stored in presets or host state. Presets can be transferred between standalone and host instances using export/import. Created by NextEpochs.
