Analyzing a Unique Pingable Circuit: The Gamelan Resonator

This paper offers a study of the circuits developed by artist Paul DeMarinis for the touring version of his work Pygmy Gamelan.

Zero-shot Singing Voice Conversion


In this paper, we propose the use of speaker embedding networks to perform zero-shot singing voice conversion, and suggest two architectures for its realization.

Moog Ladder Filter Generalizations Based on State Variable Filters

In this paper, we propose a new style of continuous-time filter design composed of a cascade of 2nd-order state variable filters (SVFs) and a global feedback path.

Speech Dereverberation using Recurrent Neural Networks


In this paper, we show how a simple reformulation allows us to adapt blind source separation techniques to the problem of speech dereverberation and, accordingly, train a bidirectional recurrent neural network (BRNN) for this task.

Energy-Preserving Time-Varying Schroeder Allpass Filters and Multichannel Extensions

We propose time-varying Schroeder allpass filters and Gerzon allpass reverberators that remain energy preserving irrespective of arbitrary variation of their allpass gains or feed- back matrices over time.

Blind Arbitrary Reverb Matching



We propose a model architecture for performing reverb matching and provide subjective experimental results suggesting that the reverb matching model can perform as well as a human.
