Compute PCC and RMSE performance bounds between objective and subjective estimates of quality.

Code in support of the ICASSP 2026 submission titled "Unseen but not Unknown: Using Dataset Concealment to Robustly Evaluate Speech Quality Estimation Models."

Open software framework for collaborative development of no reference image and video quality metrics

MATLAB tools that calculate frequency-domain (FD) (e.g., magnitude, phase, real, imaginary) signal-to-noise ratios (SNRs). Example applications include measuring audio restoration and visualizing inconsistent representations across iterations of the Griffin-Lim Algorithm (GLA).

A SigMF namespace extension for the National Telecommunications and Information Administration (NTIA).

Train no-reference speech quality estimators with multiple datasets via learned, per-dataset alignments.

Wiki for NTIA/ITS Propagation Library, built with Quarto and GitHub Pages

Base repository for creating new actions for scos-sensor and supporting new hardware.

NTIA/ITS C++ implementation of Low Frequency / Medium Frequency (LF/MF) Propagation Model. The LF/MF model predicts basic transmission loss in the frequency range 0.01 - 30 MHz for propagation paths over a smooth Earth and antenna heights less than 50 meters.
