GAITHERSBURG, Md., April 05, 2023 (GLOBE NEWSWIRE) — GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their comprehensive Audio Analysis solution – the Voice Analysis Tool (VAT™). This powerful tool can analyze audio content within Narrowband (NB), Wideband (WB), and Super Wideband (SWB) PCM audio files while generating a variety of audio metrics including Frequency Bandwidth, Speech and Noise Levels, Speech Activity, RMS Power, Audio Dropout and Delay measurements.

“The GL VAT™ application can produce various audio metrics, such as Round Trip and One Way Delay measurements, Audio Dropout analysis, Double-Talk measurements, and Voice Quality analysis (when coupled with the GL Voice Quality Testing (VQT) POLQA solution). Furthermore, the GL VAT™ supports Speech to Text analysis with pass/fail when linked with the GL Speech to Text Analysis solution,” said Robert Bichefsky, Director of Engineering at GL Communications Inc.
GL’s VAT™ performs fully automated operations by detecting audio files within a directory specified by the user and analyzing the audio files as they are created. The VAT™ tool uses configuration settings that are linked to the degraded voice file name to specify which tests to run, set configurations for each test, and associate reference files for tests that require both degraded and reference files.
The VAT™ software sends all associated results to a centralized database – GL WebViewer™. Accessing these results is done using the WebViewer™ (web browser) which includes the ability to filter, query, and generate custom reports. In addition, if results included GPS coordinates the WebViewer™ can plot results directly within Google Maps.
If the network connectivity is lost between VAT™ and the database, the data is saved internally. When connectivity is re-established, the system will automatically transmit the stored data to the GL WebViewer™ database to ensure that no data is lost.
