Atmosphere machine. Texture generator. Harmonic workstation. A dual-engine audio sustainer with intermodulation, advanced filtering, support for custom samples, and more – all in the service of adding depth and character to your music. Coastline uses a combination of additive and granular synthesis to stretch sounds infinitely. It creates complementary ambience for any sound or composition. It brings a textural “je ne sais quoi” that makes your tracks stand out and feel more alive. Move as quickly as you want: slap it on a track for instant atmosphere, or use it as the recording and processing hub of entire compositions. All recordings happen immediately and automatically – set one volume threshold, and sit back. ENGINES AND EFFECTS • Tide – an additive synthesizer for reimagining sound. Control which frequencies of the input are mapped to oscillators, rebalance them to highlight harmonic or inharmonic characteristics, and introduce new frequencies with waveshaping. • Glade – a granular synthesizer that stretches sound forever with no clicks or transients. Balance the original timbre of your sound against Tide’s distillation of it. • Audio Matrix – route any channel in Coastline to intermodulate another. Create unique harmonic distortions, or load samples to introduce a completely new texture. Includes built-in field samples for naturalistic textures. • Filter – a multi-mode filter for all audio in Coastline, featuring feedback modulation, stereo spread, and independent per-channel controls. • Reverb – a downsampling reverb with a highly configurable chorus section for blending the results of Coastline and introducing another layer of texture and modulation. FEATURES • Modulation – modify any control in Coastline with multiple LFOs, sequencers, smooth random sources, and performance effects. • Presets – full preset control over every parameter in Coastline. Cross-platform preset format for sharing with friends. • Waymaker – connect to Coastline’s sibling application, Waymaker, for sequencing and additional control over the pitch of Coastline’s output. Includes 20+ presets by Peter Bark and imago meri. Also available for macOS and Windows in VST3 / AU / AAX formats from Aqeel Aadam Sound.

About

FALSE MEMORY

This app transforms any sound into a decaying audio effect, simulating tape degradation or digital corruption. Explore various destruction parameters to create unique sonic textures and atmospheres. It can also evolve the sound automatically over time.

Highlights
  • Real-time audio disintegration
  • Analog/Digital destruction engine
  • Pitch and timing destabilization
  • Frequency spectrum smearing
  • Past audio bleed-through
  • Automatic evolution over time
  • Randomize parameters

FALSE MEMORY is a real-time audio disintegration effect. Feed it any sound and watch it decay. A tape left in the sun. A corrupted file half-recovered from a dead drive. A memory dissolving as you try to hold onto it. Turn up MEMORY and the destruction begins. Everything else shapes how the sound falls apart. DESTRUCTION ENGINE The Analog / Digital slider is the soul of the effect. Slide left for warm, organic decay: Cassette wobble, Reel-to-reel saturation, VHS tracking errors. Slide right for cold, precise corruption: Lo-fi aliasing, Circuit-bent glitches, Data-mosh block artifacts. Drift destabilizes pitch and timing. At low settings it breathes. Cranked up, the signal loses its grip on reality. Damage controls how aggressively the signal gets torn apart. ATMOSPHERE Fog smears the frequency spectrum into clouds. Three modes: Tonal keeps harmonic structure intact, Inharmonic scatters it, Evolving slowly morphs between the two. Ghosts lets past audio bleed through the current signal. Echoes repeat rhythmically. Imprints leave residual traces. Granular scatters fragments across time. TEXTURE Hiss adds tape noise, from subtle warmth to a roaring floor. Crackle introduces vinyl pops and surface damage. SET IT AND FORGET IT Evolve lets the destruction deepen automatically over time. Pick a duration from 1 to 64 minutes. Walk away. Come back to something completely different. The Randomize button rerolls all destruction parameters instantly. Hit it until something clicks. AUv3 plugin for iOS. Runs in AUM, GarageBand, Logic, and any AUv3 host. Standalone app for iPhone and iPad. From All The Machines.
