Methodological study reports a unified multidimensional measurement profile in analogue record systems, indicating reproducible cross-session comparison of vinyl playback quality.
Objective analysis of vinyl playback commonly reports speed error, wow and flutter, channel balance, crosstalk, distortion, harmonic content and noise as separate results. Those measurements are useful, but their isolation makes it difficult to preserve the technical identity of a measurement session, determine whether a later session is meaningfully different, or compare records, pressings and playback systems without losing context. This paper defines the DSR Vinyl Playback Fingerprint Method (DSR-VPF) v1.0: a persistent, versioned, multidimensional measurement object that combines heterogeneous objective results with their validity state, repeatability or uncertainty information, acquisition provenance and comparison rules. The Fingerprint is not the radar graph used to display it; the graph is one projection of an underlying machine-readable object. The first fixed profile, VPF-Core-1K v1.0, comprises speed accuracy, weighted wow and flutter, channel balance, stereo separation, directional crosstalk asymmetry and total harmonic distortion. DSR-VPF v1.0 establishes the open method architecture and initial profile. Groove Scope is designated as the first reference implementation, while empirical repeatability and inter-device reproducibility validation remain ongoing.
