Wavetable Synthesis Using CVAE for Timbre Control Based on Semantic Label
- 基于条件变分自编码器，通过语义标签控制波表音色
- 支持实时音色调节，用户只需输入如'明亮''温暖'等标签
- 适合音乐制作新手，降低音色参数使用门槛
合成器在现代音乐制作中至关重要，但其复杂的音色参数常含专业术语，需专业知识。本文提出一种基于语义标签的波表合成音色控制方法，利用条件变分自编码器（CVAE），用户可选择波表并以'明亮''温暖''丰富'等语义标签定义音色。该模型采用卷积与上采样层，在时域处理中有效捕捉波表细微特征，保证实时性能。实验表明，该方法可通过语义输入实现对波表音色的实时、高效控制，旨在通过数据驱动的语义方式实现直观音色调节。
原文摘要 · Abstract (English)
Synthesizers are essential in modern music production. However, their complex timbre parameters, often filled with technical terms, require expertise. This research introduces a method of timbre control in wavetable synthesis that is intuitive and sensible and utilizes semantic labels. Using a conditional variational autoencoder (CVAE), users can select a wavetable and define the timbre with labels such as bright, warm, and rich. The CVAE model, featuring convolutional and upsampling layers, effectively captures the wavetable nuances, ensuring real-time performance owing to their processing in the time domain. Experiments demonstrate that this approach allows for real-time, effective control of the timbre of the wavetable using semantic inputs and aims for intuitive timbre control through data-based semantic control.
