Timbre personalisation for earphones: A framework for perceptual consistency in next-generation media delivery

Tech Papers 2026: This paper presents a Personalized-Timbre Target Curve (PTTC) framework grounded in a mathematical auditory model that decomposes anatomically derived HRTFs into directional and timbral components, isolating the spectral factors that contribute to natural timbre.

Abstract

True Wireless Stereo (TWS) earphones have become the dominant playback device for broadcast, streaming, and immersive media, creating a structural challenge: maintaining perceptual consistency across highly individualised playback conditions. While video workflows rely on standardised colour...
