Recently, a dataset of time-scaled audio with\nsubjective quality labels was published and used to create an initial objective\nmeasure of quality. In this paper, an improved objective measure of quality for\ntime-scaled audio is proposed. The measure uses hand-crafted features and a\nfully connected network to predict subjective mean opinion scores. Basic and\nAdvanced Perceptual Evaluation of Audio Quality features are used in addition\nto nine features specific to TSM artefacts. Six methods of alignment are\nexplored, with interpolation of the reference magnitude spectrum to the length\nof the test magnitude spectrum giving the best performance. The proposed\nmeasure achieves a mean Root Mean Squared Error of 0.487 and a mean Pearson\ncorrelation of 0.865, equivalent to 98th and 82nd percentiles of subjective\nsessions respectively. The proposed measure is used to evaluate time-scale\nmodification algorithms, finding that Elastique gives the highest objective\nquality for Solo instrument and voice signals, while the Identity Phase-Locking\nPhase Vocoder gives the highest objective quality for music signals and the\nbest overall quality.
