What is a TV Audio Processor?

TV Audio Processors are devices that enhance the sound quality of your television broadcast.
They are very important pieces of equipment, as they are usually the last ones you use before your audio is transmitted.

In a TV station, audio processors ensure quality and consistency of audio, and are therefore essential to your television broadcast.

Functions and applications of a TV Audio Processor

These devices can perform a variety of functions, and have a number of different applications.

How do TV audio processors work?

Identically to what happens for the video signal, the audio signal of a station is first embedded into the SDI signal, to then be processed and re-embedded into the now-ready-to-be-broadcast SDI signal.


  • Dynamic range control: allows you to adjust the different audio ranges (music, dialogue, sound effects) coming from different audio sources into a cohesive sound that is pleasant to listen to.
  • Loudness control: means being able to adjust the volume consistently across several channels and programs, ensuring your audio signal has a coherent feel across all mediums.
  • Compliance with regulatory requirements: allow you to comply with the audio loudness and quality standards.
  • Improved audio quality: means that the overall sound of your television will have been "cleaned", by reducing unwanted noise and ensuring consistent volume levels.
  • Professional sound quality: your audio will sound appropriate for a professional TV broadcasting program, unlike more amateurial material, the audio of which may lack quality and crispness.


TV audio processors are mainly used in television broadcasting, studio production (including movies and shows) and streaming services across online platforms.

Types of audio processors

There are a few types of audio processors, namely:

  1. Line-level processors: used to process audio signals that are already at the standard "line level" of quality;
  2. Insertion processors: used to manipulate the audio signal that is inserted in a signal chain;
  3. Multichannel processors: used to process sourround sound signals and other multichannel audio signals, often including a variety of features.
