摘要:
使用神经音频合成模型控制音效变化一直是一项困难的任务。可微分数字信号处理(DDSP)提供了一种轻量级解决方案,通过结合预处理音频特征和数字合成器,在实现高质量声音合成的同时支持确定性的声学属性控制。在本研究中,我们提出了DDSP-SFX,这是一个基于DDSP架构的模型,能够合成高质量音效,同时使用户能够轻松控制音色变化。我们提出了一种瞬态建模技术,在脉冲信号(脚步声、枪声)上获得了更高的客观评估分数和主观评分。我们提出了一种简单的方法,在实现音色变化控制的同时也支持确定性属性控制。我们进一步以语音作为引导声音,定性地展示了音色迁移性能。
英文摘要:
Controlling the variations of sound effects using neural audio synthesis models has been a difficult task. Differentiable digital signal processing (DDSP) provides a lightweight solution that achieves high-quality sound synthesis while enabling deterministic acoustic attribute control by incorporating pre-processed audio features and digital synthesizers. In this research, we introduce DDSP-SFX, a model based on the DDSP architecture capable of synthesizing high-quality sound effects while enabling users to control the timbre variations easily. We propose a transient modelling technique with higher objective evaluation scores and subjective ratings over impulsive signals (footsteps, gunshots). We propose a simple method that achieves timbre variation control while also allowing deterministic attribute control. We further qualitatively show the timbre transfer performance using voice as the guiding sound.
