Computational Tonality Estimation: Signal Processing and Hidden Markov Models [PDF]

, 2009
PhDThis thesis investigates computational musical tonality estimation from an audio signal. We present a hidden Markov model (HMM) in which relationships between chords and keys are expressed as probabilities of emitting observable chords from a hidden

Audio Peak Reduction Using Ultra-Short Chirps

, 2022
Two filtering methods for reducing the peak value of audio signals are studied. Both methods essentially warp the signal phase while leaving its magnitude spectrum unchanged.

Neural Modeling of Phaser and Flanging Effects [PDF]

, 2021
This article further explores a previously proposed gray-box neural network approach to modeling LFO (low-frequency oscillator) modulated time-varying audio effects. The network inputs are both the unprocessed audio and LFO signal. This allows the LFO to

Perceptual Loss Function for Neural Modelling of Audio Systems

, 2020
This work investigates alternate pre-emphasis filters used as part of the loss function during neural network training for nonlinear audio processing. In our previous work, the error-to-signal ratio loss function was used during network training, with a ...
