Audio Files

The data from the NOAA buoys is provided in several different formats. I choose to use the Continuous Wind data, polled every 10 minutes for the audio file that would be granulated. This data is cataloged historically by year and available as a text document with different pieces of data delineated by tabs. (see Image below). Where the censor failed to report data a 999 or 99 placed in the  file. 

Using MATLAB I formatted the data so that the continuous wind-speed occupied a single row. This data was then scaled to occupy the -1 to 1 range and finally output to an audio file. Each wind observation constitutes an individual sample. The missing data points were replaced by an average of the adjacent points. Below is a soundfile that contains the audio data from the year 2009.
