Author: J. S. Audiorhythm Affiliation: Center for Computational Sound Design, Berlin Published in: Journal of Creative Audio Engineering , Vol. 14, Issue 2, 2026 Abstract The tape stop effect—a rapid, non-linear deceleration of playback pitch and amplitude—originated from analog reel-to-reel machines but has become a staple of electronic, hip-hop, and glitch music production. This paper introduces and analyzes the dBlue Tapestop , a software effect unit that combines classic tape stop emulation with granular resynthesis and digital control. Unlike simple pitch ramps, the dBlue Tapestop simulates mechanical inertia, scrape flutter, and post-stop motor resonance. We describe its core algorithm, compare it to physical tape dynamics, and evaluate its perceptual impact on rhythmic material. Our results show that the dBlue Tapestop offers superior transient preservation and creative parameter modulation compared to standard DAW pitch bending. 1. Introduction Digital audio workstations (DAWs) often lack the unpredictable, organic artifacts of analog tape. The tape stop effect—where playback slows to a halt—creates a dramatic rhythmic reset, tension release, or transitional swoop. Early digital emulations used simple linear pitch ramps (e.g., 44100 Hz → 0 Hz over 200 ms), but these sounded synthetic. dblue tapestop
