Kapre: On-GPU Audio Preprocessing Layers for a Quick Implementation of Deep Neural Network Models with KerasKeunwoo Choi, Deokjin Joo, Juho Kim
We introduce Kapre, Keras layers for audio and music signal preprocessing. Music research using deep neural networks requires a heavy and tedious preprocessing stage, for which audio processing parameters are often ignored in parameter optimisation. To solve this problem, Kapre implements time-frequency conversions, normalisation, and data augmentation as Keras layers. We report simple benchmark results, showing real-time on-GPU preprocessing adds a reasonable amount of computation.
