HearSonic is a reactive granular processor with band-selective spectral feedback for live audio, built primarily for outdoor headphone listening. It also works as an AUv3 effect on instruments and recordings in a host. It combines several processing chains to produce rich overlays and warm or dark tonal shifts in received audio which transforms user's listening environment. - shape the sound with Sound Field sphere, Dark & Bright amounts, and many parameters - parameters sets can be saved in a session - standalone works with default microphone input only (you need headphones, otherwise the processing will not start) - has 'History Recording' with configurable length which runs continuously and allows capturing past moments - On device motion sensors can be used for sound field movement - MIDI In for chosen parameter - works as AU plugin in audio hosts with adjusted input signal processing
