Data and Introduction

The data set I chose to examine is taken from the levels of the Rhine River (near Basel, Switzerland) between 1807 and 1957. I have no idea why I decided to use this data. The file sounds sort of like a siren that increases volume and intensity in a cycle of three and then repeats a similar pattern with slightly different frequencies. I increased the ms that drawn-out droning siren sound that makes time seem to move slowly rather than a quicker one.

Here is the wav file...not all that pleasent to listen to:

Here is the dataset:

Here is the link to the ChucK file:

Questions

1. Squaring the values for gain makes the sound easier to distinguish. This change makes the values non-linear and able to be interpreted by humans. This saves our eardrums and our speakers.

2. Different pitch changes become possible ... the pitch becomes hareder to distinguish.

3. If increased, teh data will be played slower (the opposite if decreased).
