Package: mcvqoe-tvo
SummaryThe purpose of this software is to find the optimal transmit volume for a push-to-talk (PTT) communications device performing Mission Critical Voice (MCV) quality of experience (QoE) measurements using a transmit volume optimization (TVO) tool. TVO should be performed for every combination of PTT device under test and every audio file used in performing MCV QoE measurements.Additional scripts not mentioned in the README that live in the repository are helper functions utilized in the main scripts listed.Obtaining SoftwareCode available at:https://github.com/usnistgov/MCV-QOE-TVOData available at:https://doi.org/10.18434/mds2-2432Paper available at:https://doi.org/10.6028/NIST.TN.2171Obtaining DataData is available at:https://doi.org/10.18434/mds2-2432Hardware RequirementsSee the following:Optimal Transmit Volume Conditions for Mission Critical Voice Quality of Experience Measurement Systemshttps://doi.org/10.6028/NIST.TN.2171Mission Critical Voice QoE Access Time Measurement Methodshttps://github.com/usnistgov/accessTimehttps://www.nist.gov/ctl/pscr/mission-critical-voice-qoe-access-time-measurement-methodsAdditional details and information can be found in the paper linked above.Running TVOInstalling SoftwareTo install the software runpip install mcvqoe-tvoAlternatively, one could clone this repository and run the following from the root of the git repository:pip install .Running a measurementThe easiest way to use the measurement system is to run the GUI (https://github.com/usnistgov/mcvqoe).Audio FilesAudio files can be found in themcvqoe/tvo/audio_clipsfolder. By default, all four of these audio files are used. The csv files with cutpoints, as well as the test wav files, are included.TECHNICAL SUPPORTFor more information or assistance on access delay measurements please contact:Public Safety Communications Research DivisionNational Institute of Standards and Technology325 BroadwayBoulder, CO 80305PSCR@PSCR.govDisclaimerMuch of the included software was developed by NIST employees, for that software the following disclaimer applies:This software was developed by employees of the National Institute of Standards and Technology (NIST), an agency of the Federal Government.
