1.8 Histogram

V4 Logger

Histogram:

The Histogram provides a waveform time based graph to display when audio (and relative level) was

present and at what time. This is particularly convenient when validating an audio source such a

satellite feed, to confirm audio was present at a specific time. This is also a good diagnostic tool to

verify if audio is being received on any channel.

The start time is displayed in the bottom right hand corner of each Histogram window while the

channel information is displayed on the left. To view all information on long file recordings, there is a

scroll bar underneath each window to allow the user to scroll from start to current or finish time.

The left channel as displayed above is plotted in a blue color while the right is displayed in red.
