This technical report describes the CP-JKU team’s submissions for Task 1 - Subtask A (Acoustic Scene Classification, ASC) of the DCASE-2018 challenge. Our approach is still related to the methodology that achieved ranks 1 and 2 in the 2016 ASC challenge: a fusion of i-vector modelling using MFCC features derived from left and right audio channels, and deep convolutional neural networks (CNNs) trained on spectrograms. However, for our 2018 submission we have put a stronger focus on tuning and pushing the performance of our CNNs. The result of our experiments is a classification system that achieves classification accuracies of around 80% on the public Kaggle-Leaderboard.
