Experimental Stimuli for Auditory Grouping Perception of Odd and Even Harmonic Components

This dataset contains the auditory stimuli used in the listening experiments reported in the associated manuscript on auditory grouping perception. The stimuli were derived from musical instrument tones and resynthesized in order to separate odd-harmonic and even-harmonic components. Experimental stimuli were constructed by mixing these components at controlled sound pressure level ratios. Three original sound sources were used: P1 : Piano (pitch A3)T1 : Trombone (pitch B2)T2 : Trombone (pitch B3) For each sound source, stimuli were generated under two presentation conditions: diotic : monaural presentationdichotic : stereo presentation with channel-dependent level differences For each presentation condition, 15 stimuli were generated with different level ratios between odd and even harmonic components. Total number of experimental stimuli:3 sound sources × 2 presentation conditions × 15 conditions = 90 stimuli Each sound source folder also contains the following reference signals: (SoundSource)_original.wav : original instrument tone(SoundSource)_odd.wav : odd-harmonic component(SoundSource)_even.wav : even-harmonic component(SoundSource)_residual.wav : residual component The dataset is organized using a structured folder hierarchy. A README file is included to explain the directory structure and file naming conventions. These stimuli were used in perceptual experiments investigating auditory grouping and spectral integration of harmonic components.
