Loudness Analyzer is a software technology for check and normalization of the volume level of audio-or video files according to legislative arrangements. It is focused on use by television and radio broadcasting companies.
According to each Loudness Analyzer file provides information:
- quantity of audiotracks
- duration of audiotracks.
Information is available to each audiotrack:
- number of channels
- duration
- maximum level of real peak values
- maximum level of instant volume
- maximum level of short-term volume
- integrated volume
- volume range.
General information about the file:
- information on the video codec
- information on the audiocodec.
The application allows to trace dynamics of change of short-term and instant volume on diagrams with temporary coding and a possibility of zooming.
Loudness Analyzer in the manual mode allows adjustment of threshold values of the volume level. The product allows to change in a separate window the file volume level according to the selected values.
A system analyzes files in manual (the selected files) and the automatic mode when the application monitors the specified folders and analyzes all files from these folders.
The application allows to save analysis results in files with the .xlsx and .xls expansions.
2017: There was a release of the version of Loudness Analyzer
On June 23, 2017 the Tekom company announced release of the version of Loudness Analyzer with a possibility of mapping and automatic normalization.
Function of mapping allows to integrate channels from different tracks, to analyze and normalize[1] according to the set settings[1].
 | In the version of Loudness Analyzer we tried to make the solution more flexible in terms of the analysis of audiosignals. Now the product allows to calculate volume parameters regardless of how tracks and channels in the media file are distributed. For example, in case the binaural sound is written in different tracks, Loudness Analyzer allows to analyze them together. Alexey Dolgov, area director R&D |  |
In the application version the possibility of automatic normalization of a sound appeared during the analysis of files, and broadcasters can automate process of control of volume of air, without involving additional employees.
