FeedbackFlut

FeedbackFlut is an experimental musical instrument and software environment designed for live performance and sound design. Created by a collaborative group of artists and engineers, it enables players to sculpt evolving textures through controlled audio feedback. The system combines a wind-controlled flute-like interface with a modular DSP chain that processes breath-driven input into feedback-rich soundscapes, blending acoustic and electronic timbres.

The hardware interface resembles a flute or whistle and uses breath sensors, pressure sensors on the lips, and optional fingerings to modulate parameters. The signal path routes the acoustic input through digital feedback loops, with delay lines, filters, dynamic processors, and granular or spectral synthesis. Built-in safety controls limit gain and prevent runaway oscillation while still allowing intense textures.

Software aspects include a modular DSP framework with configurable routing, presets, and live-coding capabilities. The core is open source, supporting MIDI, OSC, and CV outputs to external gear. Users can rewire the processing graph, add third-party plugins, and share patches via an online repository. The project emphasizes interoperability and portability across desktop and embedded platforms.

Since its release in the late 2010s, FeedbackFlut has been used in avant-garde performances, academic demonstrations, and experimental studios. Critics note its potential for richly tactile microtonal textures but point to a steep learning curve and the need for careful level management during high-gain feedback.
