Generative models in vision have seen rapid progress due to algorithmic improvements and the availability of high-quality image datasets. In this paper, we offer contributions in both these areas to enable similar progress in audio modeling. First, we detail a powerful new WaveNet-style autoencoder model that conditions an autoregressive decoder on temporal codes learned from the raw audio waveform. Second, we introduce NSynth, a large-scale and high-quality dataset of musical notes that is an order of magnitude larger than comparable public datasets. Using NSynth, we demonstrate improved qualitative and quantitative performance of the WaveNet autoencoder over a well-tuned spectral autoencoder baseline. Finally, we show that the model learns a manifold of embeddings that allows for morphing between instruments, meaningfully interpolating in timbre to create new types of sounds that are realistic and expressive.

本研究提出了一种基于WaveNet风格自编码器的新型音频模型，进一步介绍了一个规模较大质量较高的音乐数据集NSynth。使用NSynth数据集，我们证明WaveNet自编码器比使用频谱自编码器基线的性能有显著提高，同时演示了该模型学习嵌入的能力，实现了在音色上的差值并创造了新类型的逼真和有表现力的声音。
