8-Head Continuous Tape Loop Delay Cartridge with Motorized Flutter

PROT-006: TAPE-MULTITAPCLEARANCE: 1-ALPHASTATUS: ACTIVE BENCHYEAR: 2026

Discipline: Experimental Audio Systems · Lead Researcher: Soren Lindqvist

OPERATIONAL ABSTRACT

A speculative electro-mechanical delay unit utilizing continuous magnetic tape loops across eight adjustable read heads, featuring motorized capstan flutter modulation.

TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS

Staggered permalloy playback heads with micrometer adjustment screws feed an active summing mixer. Dual direct-drive capstan motors introduce organic tape flutter and chorusing. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
