Tide table audiograph

The graphs are jpegs, the tables too. and the tables don't have evenly spaced samples.

It's probably easier to find the generating function and use octave or matlab or a spreadsheet or something like that to convert that to samples that can be converted to wav.

At ~1Khz 2012's data is going to get you

I know the data has to come from elsewhere. 2 tides a day for 365 days would make a very short MP3 at 1kHz. It would take almost 7 years data to make a 5 minute "song". I bet NOAA has data from back quite a few years.

Maybe Mr. Google can help? Yes!

Ha! If I could do math those formulas could feed an amp directly. I wonder if Octave or Matlab mentioned above can input formula 17.16?

I'm not real knowledgeable about tides, but in our local bay the dc component changes with season and the amplitude is modulated by prevailing winds and I assume barometric pressure. Then you can throw in the wake of small fishing boats, large container ships and a few Navy vessels, including hovercraft. Hey, I have a very musical area! It seems without these other effects the tune would get repetitive. Mikek

Certainly. However, Table 17.2 has the period and amplitude of the constituents already worked out, so it's really just a matter of summing each over time.

If you want the actual tidal predictions for a non-ideal Earth and at a particular real tidal station, it gets a little trickier.

Aha! Take a look at

I can't visualize table 17.2

Also don't understand "important concepts" at the end of the chapter.

a.. Tides have six fundamental frequencies. The tide is the superposition of hundreds of tidal constituents, each having a frequency that is the sum and difference of five fundamental frequencies.

Reminds me of the function of a theremin which only uses 2 frequencies. Time to give up.

Holy crap - someone already did this.

Thanks much for finding such a weird audio artifact.

I can get back to whatever I was supposed to be doing.

Here's one, kind of cool:

Ok, so this is silly as hell...

This is what it sounds like when you play the six tide-generations on the bottom at the same time...

So is posting a binary to a non-binary newsgroup, (sci.electronics.basics).

Sorry, thought I was posting it to mp3.experimental only. Have a bran muffin, relax, pull the stick from your ass... see? The world still turns!

The world also still turns after murder and genocide; so that is hardly an applicable excuse for small transgressions. :)
