Before revision:  To address this issue, we introduce a general audio-to-spiking conversion procedure and provide two novel spike-based classification datasets . The datasets are free and require no additional preprocessing, which renders them broadly applicable to benchmark both software and neuromorphic hardware implementations of spiking neural networks  .
