<p>The apparatus comprises a video/audio tape recorder (1) connected, via an audio output (2), to a frequency analyser (3). The frequency analyser (3) divides the frequency components of the audio material into a plurality of frequency bandwidths over a period of time and the value for each bandwidth is digitised and transmitted to a computer (8) with a colour graphic output (9). After transmission to the computer, a transformation is carried out on the data to represent the values of the bandwidth as different colours in the form of colour video data. The colour video data is visually displayed on a screen (10) in the form of a coloured representation (11). One or more frames (13) of video material may be displayed simultaneously with the coloured representation (11) on the same screen (10) or on another screen (14).</p> |
