To do this, we first perform spectral pre-processing, and then extract features, followed by machine learning, for dimensionality reduction. The features are then mapped to the parameters of a sound synthesiser, as part of the audio processing, so as to generate audio samples in order to compute statistical results and identify important descriptors for the classification of the dataset. To optimise the process, we compare Amplitude Modulation (AM) and Frequency Modulation (FM) synthesis, as applied to two real-life datasets to evaluate the performance of sonification as a method for discriminating data. FM synthesis provides a higher subjective classification accuracy as compared with to AM synthesis. We then further compare the dimensionality reduction method of Principal Component Analysis (PCA) and Linear Discriminant Analysis in order to optimise our sonification algorithm. The results of classification accuracy using FM synthesis as the sound synthesiser and PCA as the dimensionality reduction method yields a mean classification accuracies of 93.81% and 88.57% for the <jats:italic>coffee dataset<\/jats:italic> and the <jats:italic>fruit puree dataset<\/jats:italic> respectively, and indicate that this spectroscopic analysis model is able to provide relevant information on the spectral data, and most importantly, is able to discriminate accurately between the two spectra and thus provides a complementary tool to supplement current methods.<\/jats:p>","DOI":"10.1007\/s10772-020-09794-9","type":"journal-article","created":{"date-parts":[[2021,1,14]],"date-time":"2021-01-14T04:00:38Z","timestamp":1610596838000},"page":"865-881","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A model for spectroscopic food sample analysis using data sonification"],"prefix":"10.1007","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9260-4105","authenticated-orcid":false,"given":"Hsein","family":"Kew","sequence":"first","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,1,13]]},"reference":[{"issue":"10","key":"9794_CR1","doi-asserted-by":"publisher","first-page":"9934","DOI":"10.1364\/OE.18.009934","volume":"18","author":"A Ahmad","year":"2010","unstructured":"Ahmad, A., Adie, S.
