Accelerating Automatic Differentiation of Direct Form Digital Filters

Chin-Yun Yu, György Fazekas

We introduce a general formulation for automatic differentiation through direct form filters, yielding a closed-form backpropagation that includes initial condition gradients. The…

Improving Inference-Time Optimisation for Vocal Effects Style Transfer with a Gaussian Prior

Chin-Yun Yu, Marco A. Martínez-Ramírez, Junghyun Koo +3

Style Transfer with Inference-Time Optimisation (ST-ITO) is a recent approach for transferring the applied effects of a reference audio to an audio track. It optimises the effect p…

Multi-layered Cepstrum for Instantaneous Frequency Estimation

Chin-Yun Yu, Li Su

We propose the multi-layered cepstrum (MLC) method to estimate multiple fundamental frequencies (MF0) of a signal under challenging contamination such as high-pass filter noise. Ta…
