ABC-MRT16
Articulation Band Correlation Modified Rhyme Test
alignnet
Train no-reference speech quality estimators with multiple datasets via learned, per-dataset alignments.
Audio-FD-SNRs
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).
Dataset-Concealment
Code in support of the ICASSP 2026 submission titled "Unseen but not Unknown: Using Dataset Concealment to Robustly Evaluate Speech Quality Estimation Models."
ehata
The Extended Hata (eHata) Urban Propagation Model
FMS
Code that implements the fixed-size modulation spectrum (FMS), which is a perceptually-relevant, fixed-size representation for an audio (.wav) file.
gilbert-elliot-model
Tools for manipulating the Gilbert-Elliot burst error model.
gnuradio-docker
Script automation for creating canonical GNU Radio docker images
gr-mapper
Symbol to Bit Mapping and Demapping Blocks for GNU Radio
if77-gierhart-johnson
IF-77 Air-to-Ground Propagation Model (Gierhart-Johnson)
ILM
The Irregular Lunar Model
itm
ITS Irregular Terrain Model (ITM), which predicts terrestrial radiowave propagation for frequencies between 20 MHz and 20 GHz based on electromagnetic theory and empirical models developed by Anita Longley and Phil Rice.
itm-longley-rice-dev
ITS Irregular Terrain Model (Longley-Rice)
ITS-MOS-Agreement
Compute PCC and RMSE performance bounds between objective and subjective estimates of quality.
LFMF
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.
LFMF-python
Python wrapper for the NTIA/ITS implementation of the Low Frequency / Medium Frequency (LF/MF) Propagation Model. LF/MF 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.
LFMF-test-data
This repository contains a dataset used to test the NTIA/ITS implementations of the Low Frequency / Medium Frequency (LF/MF) Propagation Model.
NRMetricFramework
Open software framework for collaborative development of no reference image and video quality metrics
p2108
NTIA/ITS implementation of Recommendation ITU-R P.2108. This Recommendation contains three methods for the prediction of clutter loss: the Height Gain Terminal Correction Model, the Terrestrial Statistical Model, and the Aeronautical Statistical Model.
p2108-python
Python wrapper for U.S. Reference Software Implementation of Recommendation ITU-R P.2108
p2108-test-data
This repository contains a dataset used to test the NTIA/ITS implementations of Recommendation ITU-R P.2108.
p528
U.S. reference implementation of Recommendation ITU-R P.528 providing propagation path loss predictions for aeronautical mobile and radionavigation services using the VHF, UHF, and SHF bands
p528-gui
A graphical user interface application for Recommendation ITU-R P.528
