Raw Data

Morsenger samples Raw Data from the camera and microphone 10 times per second and stores this internally until it can be translated into Morse Code. Raw Data is simply a list of floating point numbers that represent relative audio volume or luminous intensity. This data is processed into a Bit Stream and ultimately into received messages.

1.23 2.44 5.66 2.11 0.11 -2.11 etc

Raw Data represents the received morse signal level that is recorded at fixed sampling intervals (usually every 11 msec).

It is normally pre-processed to remove noise and adjusted for slow overall fluctuations in amplitude. The numbers can represent audio volume, the strength of the dominate frequency or the average light level detected at the time of sampling. This pre-processing normally trims all but a few milli-seconds of silence from either end of the Raw Data sequence.
