Description
Sound-driven design requires methods that transform complex source data into auditory stimuli in ways that remain transparent, reproducible, and suitable for evaluation. This contribution presents a workflow for generating listening-ready stimuli from molecular vibrational structure and examining how specific design decisions influence the resulting auditory experience. The primary contribution is methodological rather than molecular: glycine serves as a compact demonstration case because its vibrational features are well documented and readily traceable throughout the workflow.Starting from an IR/Raman peak list, vibrational features are mapped to audible carriers through explicitly documented frequency and amplitude transforms. Temporal structure is then introduced through controlled envelope design. Two envelope families are provided: an evaporation-style reference envelope and a multi-phase kinetic-inspired envelope used as a design hypothesis for exploring how alternative temporal trajectories influence listening impressions. To support transparent comparison, the framework also generates envelope-swapped, time-scrambled, and loudness-matched controls. Together, documented mappings, controlled stimulus variants, and reproducible comparison conditions provide an objective basis for evaluating design choices.The workflow is intended for applications where the relationship between source data, design decisions, and perceptual outcomes must remain visible and auditable. Potential uses include sonification practice, product sound-quality research, where envelope design can be assessed as a controllable sound-design variable, and educational settings in which students can modify mapping parameters and evaluate their audible consequences. A synchronized visual representation supports design iteration and teaching activities. All assets are released with metadata, mapping specifications, and integrity records. The resulting contribution is a reusable methodology for generating, comparing, and evaluating auditory stimuli while maintaining traceability from source data to listening outcome.
