ESC50Mix dataset

Reference: Jakob Abeßer, Sascha Grollmisch, Meinard Müller, How Robust are Audio Embeddings for Polyphonic Sound Event Tagging? (to be published in IEEE/ACM Transactions on Audio, Speech, and Language Processing) The dataset builds upon the ESC-50 dataset (https://github.com/karolpiczak/ESC-50) and creates mixtures of two random sound pairs by systematically blending from one to the other sounds. In total, the dataset includes 30,000 5s audio clips - 1000 sound pairs - 6 gain factors (used for mixing pairs) - 5 data augmentations (none, loudness reduction, Gaussian noise, high-frequency boost, low-frequency boost)
