摘要:

从音乐片段中提取频谱特征是一项计算量很大的任务。因为为了提取准确的特征,我们需要处理整个长度的剪辑。这个预处理任务会产生很大的开销,并且也会使提取过程变慢。我们展示了如何以某种方式格式化数据集,可以通过消除在整个持续时间内处理剪辑的需要来帮助提高过程的效率,并且仍然准确地提取特征。此外,我们还讨论了在训练时定义一组通用持续时间以分析某种类型的音乐片段的可能性。通过这样做,我们将处理剪辑持续时间的需求减少到全球平均水平的10%。

英文摘要:

The extraction of spectral features from a music clip is a computationally expensive task. As in order to extract accurate features, we need to process the clip for its whole length. This preprocessing task creates a large overhead and also makes the extraction process slower. We show how formatting a dataset in a certain way, can help make the process more efficient by eliminating the need for processing the clip for its whole duration, and still extract the features accurately. In addition, we discuss the possibility of defining set generic durations for analyzing a certain type of music clip while training. And in doing so we cut down the need of processing the clip duration to just 10% of the global average.
