RF-GML: Reference-Free Generative Machine Listener

open access: yes
This paper introduces a novel reference-free (RF) audio quality metric called the RF-Generative Machine Listener (RF-GML), designed to evaluate coded mono, stereo, and binaural audio at a 48 kHz sample rate.

Improvements on Transient Signal Detection for Rf Fingerprinting

open access: yes, 2017
The detection of the transient signal plays a significant role in RF fingerprinting for transmitter devices. This paper proposes modifications on two transient signal detection methods, namely, Bayesian change point detection and phase based detection ...
