Coastline uses two sustaining algorithms to resynthesize audio and stretch it forever.

• 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 distilled version.

Coastline’s Audio Matrix lets you route any channel to intermodulate another, or itself. Create unique harmonic distortions, or load samples to introduce a completely new texture. Coastline includes built-in field samples by Nathan Moody for naturalistic textures.

Furthermore, manipulate any control in Coastline with a fully fledged Modulation matrix, including multiple LFOs, sequencers, smooth random sources, and performance effects.
