Audio-description Module


The audio-description module of Noblurway Mosaic allows to create comments of an audio-description for one or two voices. Through the display of the audio waveform, the audio-descriptor quickly identifies each silence where he can put a comment. The text is then entered on the rythmo band while precisely controlling synchronization with the area of silence. During the recording session, the actor reads the scrolling text of comments  while benefiting  from the assurance of having an ideal voice flow in order to stay in the areas of silence.

The writing of comments



Comments are entered on a scrolling text track as a digital rythmo band. The text is placed directly on the current image and can be stretched to take up the available space. In case of comments for two voices (man and woman), it is possible to add a second text track to the project for the writing of comments of the second voice. Unlike methods using a paper script, it is not necessary to note the timecode of the comment, it is automatically assigned when entering text.


Writing of audio-description in Noblurway Mosaic



The work is easier thanks to the visualization of an audio waveform which allows to identify more quickly  possible areas of writing (no dialogue, noise, music). Moreover, an additional text track is available in order to write notes such as information regarding the performance of the actor.



It is possible to export, in a document, the text of the comments with timecodes and notes of writing.

Recording in studio



During recording sessions, the video is displayed in full-screen with comments scrolling in the form of a digital rythmo band. Sessions are faster than those which are done with conventional methods based on the reading of a paper script of comments. Indeed, with the audio-description module, the voice flow of each comment is checked and adjusted by the audio-descriptor at the moment of the writing, which guarantees to the actor the fact of being able to read the comment in the allocated time. To save time, there is a command allowing to move directly to the next comment *.

In order to make easier the integration of Noblurway Mosaic in a studio, it can be synchronized in two ways: 1) using the RS-422 protocol or 2) using a LTC signal (chase timecode). In both cases, Noblurway Mosaic is slave to another machine. In the RS-422, the use of a USB422V CB Electronics interface with input video reference guarantees a very accurate synchronization.

*This feature is only available in case of RS-422 synchronization

Versions of the audio-description module

The audio-description module is available in three versions:

  • Writing Version for the audio-descriptors: it allows to write comments.
  • Projection Version for recording studios: it allows to display in full-screen the video and the digital rythmo band and it includes servomechanisms with specific recording features.
  • Studio Version: it combines features of the Writing version and the Projection version.

The following table is a summary of the main features associated with different versions of the audio-description module:





Writing of comments for 1 or 2 voices


Writing of notes


Display of an audio waveform


Text and tools research for writing


Comments text and timecodes export


Direct movement on comments

Synchronization (RS-422 and LTC sync in option)
