Courtroom Audio Recording System

MaestroVision provides courtrooms with next generation recording capabilities in a highly cost effective package. This powerful and intuitive technology records all courtroom sessions.

An audience recording station is required for each courtroom and remote location. It must be of very high quality and allow recordings of multiple audio channels (normally six). The audio channels must be recorded independently to allow for replaying an individual track. This is crucial in cases where two or more persons are talking simultaneously in order to ensure that recordings do not become inaudible and inadmissible.


  • Audio and video in high definition
  • Ability to record between four to eight independent audio sources simultaneously: the defendant, the accused, the judge and the jury, etc.
  • Advanced security features to protect content
  • Content indexing technology

Audio Recording

The system will record between four to eight independent audio tracks according to the number of microphones in each courtroom. Some microphones will be combined together in courtrooms where there are more than eight audio sources. Audio sources include microphones and other audio feeds such the audio output of the Polycom Interactive Video System.  It is important to record individual audio tracks. When all microphones are combined to two audio tracks, it is often difficult to clearly understand speech. Coughing, page turning and other audible distractions often make it difficult to comprehend the person speaking, when listening to a replay.

A combination of audio processor (16 inputs – 8 outputs and 8 inputs- 8 outputs) will be installed in each courtroom. The audio processor will allow full control of mixing, levelling, routing and processing the audio sources. The following figure shows a configuration of eleven microphones and the polycom System.
