Albalá expands its TL2000 line with an eight-channel audio normalizing processor

Albalá Engineers incorporates the HAM2008C01 normalizing processor into its TL2000 line, capable of automatically managing the level of eight audio signals.

It has been designed to function as a autonomous module working with the four AES/EBU frames that it receives through its input/output connector or in conjunction with some other module of the TL2000 line, such as the frame synchronizers, if you want to process the audio framed in the video, or the different front-end modules that allow the inputs and outputs to be analog audio or AES/EBU digital audio.

With this module, it is possible limit exaggerated jumps in audio level when changing between programs and advertisements or between channels, as required by the regulations ITU-R BS.1770 and EBU R 128 regarding loudness, that is, regarding the sensation of sound level that people perceive, as well as in the current General Law of Audiovisual Communication, which establishes that the sound level of television advertisements cannot be higher than the average level of the program that precedes it. This regulation seeks to prevent advertisements from being perceived as stronger and more disruptive than the content being viewed.

In addition to this loudness measurement, the HAM2008C01 also performs the measurements of the true peak value of audio signals (true peak), as provided in the aforementioned recommendations of the EBU and ITU.

In addition to the audio processing functions described, the HAM2008C01 also has a audio pair switching matrix which allows their reassignment and addition. Additionally, the module detects if the AES pairs carry non-PCM audio and in that case it does not process or modify them.
