Learning Filters in Feedback Delay Networks from Noisy Room Impulse Responses
Gloria Dal Santo, Karolina Prawda, Sebastian J. Schlecht +1
Recursion is a fundamental concept in the design of filters and audio systems. In particular, artificial reverberation systems that use delay networks depend on recursive paths to…
AnyRIR: Robust Non-intrusive Room Impulse Response Estimation in the Wild
Kyung Yun Lee, Nils Meyer-Kahlen, Karolina Prawda +2
We address the problem of estimating room impulse responses (RIRs) in noisy, uncontrolled environments where non-stationary sounds such as speech or footsteps corrupt conventional…
Similarity Metrics For Late Reverberation
Gloria Dal Santo, Karolina Prawda, Sebastian J. Schlecht +1
Automatic tuning of reverberation algorithms relies on the optimization of a cost function. While general audio similarity metrics are useful, they are not optimized for the specif…
Optimizing tiny colorless feedback delay networks
Gloria Dal Santo, Karolina Prawda, Sebastian J. Schlecht +1
A common bane of artificial reverberation algorithms is spectral coloration in the synthesized sound, typically manifesting as metallic ringing, leading to a degradation in the per…
FLAMO: An Open-Source Library for Frequency-Domain Differentiable Audio Processing
Gloria Dal Santo, Gian Marco De Bortoli, Karolina Prawda +2
We present FLAMO, a Frequency-sampling Library for Audio-Module Optimization designed to implement and optimize differentiable linear time-invariant audio systems. The library is o…
