An Objective Measure of Quality for Time-Scale Modification of Audio

“…Normalizing was found to slightly extend the range of the SMOS values, with higher ratings for high quality files, and lower ratings for low quality files. Given the ITU-T (2019) recommendation of normalization, and the improvement in all metrics after normalization (Roberts and Paliwal, 2020), the final proposed objective measure of quality was trained to normalized SMOS using features aligned using interpolation to test, including reference files.…”
