Feedback Delay Network Optimization

1 code implementation17 Feb 2024 Gloria Dal Santo, Karolina Prawda, Sebastian J. Schlecht, Vesa Välimäki

A common bane of artificial reverberation algorithms is spectral coloration, typically manifesting as metallic ringing, leading to a degradation in the perceived sound quality.

Deep Room Impulse Response Completion

no code implementations1 Feb 2024 Jackie Lin, Georg Götz, Sebastian J. Schlecht

The RIR completion can be widely adapted to enhance RIR generation tasks where fast late reverberation approximation is required.

Damping Density of an Absorptive Shoebox Room Derived from the Image-Source Method

no code implementations11 Oct 2023 Sebastian J. Schlecht, Karolina Prawda, Rudolf Rabenstein, Maximilian Schäfer

The paper elaborates on the proposed damping density's applicability to modeling multi-sloped sound energy decay, predicting reverberation time in non-diffuse sound fields, and fast frequency-dependent RIR synthesis.

Neural network for multi-exponential sound energy decay analysis

1 code implementation19 May 2022 Georg Götz, Ricardo Falcón Pérez, Sebastian J. Schlecht, Ville Pulkki

An established model for sound energy decay functions (EDFs) is the superposition of multiple exponentials and a noise term.

Physical Modeling using Recurrent Neural Networks with Fast Convolutional Layers

no code implementations21 Apr 2022 Julian D. Parker, Sebastian J. Schlecht, Rudolf Rabenstein, Maximilian Schäfer

Recent work has applied the techniques of machine-learning to construct such models automatically from data for the case of systems which have lumped states described by scalar values, such as electrical circuits.

Allpass Feedback Delay Networks

no code implementations14 Jul 2020 Sebastian J. Schlecht

In the 1960s, Schroeder and Logan introduced delay line-based allpass filters, which are still popular due to their computational efficiency and versatile applicability in artificial reverberation, decorrelation, and dispersive system design.
