基于卷积神经网络的音频频谱图表示

Audio Spectrogram Representations for Processing with Convolutional Neural Networks

National University of Singapore(新加坡国立大学)

L. Wyse

摘要:

在为任何应用设计神经网络时出现的决策之一是数据应该如何表示,以便呈现给神经网络并可能由其生成。对于音频,选择似乎不像视觉图像那样明显,并且各种表示已用于不同的应用,包括原始数字化样本流、手工制作的特征、机器发现的特征、包括增量的MFCC和变体以及各种频谱表示。本文回顾了其中的一些表示和出现的问题,特别关注使用神经网络生成音频的风格转移的频谱图。

英文摘要:

One of the decisions that arise when designing a neural network for any application is how the data should be represented in order to be presented to, and possibly generated by, a neural network. For audio, the choice is less obvious than it seems to be for visual images, and a variety of representations have been used for different applications including the raw digitized sample stream, hand-crafted features, machine discovered features, MFCCs and variants that include deltas, and a variety of spectral representations. This paper reviews some of these representations and issues that arise, focusing particularly on spectrograms for generating audio using neural networks for style transfer.
