I have a list of numbers from a simulation of acoustic pressure generated by a virtual musical instrument by another program (Comsol multiphysics). I would like to "hear" the tone produced by different settings in the virtual instrument.

How can I do this? In particular, can I convert the data into a .wav file?

In Mathematica it is easy to turn any time series data into sound. Here are the Boston temperatures for a few decades:

data = WeatherData["Boston", "MeanTemperature", {{1970}, {2012}, "Day"}];
DateListLogPlot[data, PlotStyle -> PointSize[0], AspectRatio -> 1/5]

enter image description here

To turn it into sound and play it in a Mathematica notebook:

ListPlay[data[[All, 2]], SampleRate -> 2000]

enter image description here

To export to .wav file:

Export["test.wav", %]
  • $\begingroup$ +1 Very nice example! I personally like the sound of the RiemannZeta function. $\endgroup$

  • $\begingroup$ @Matariki Thanks! I am not sure about sampling rate for RiemannZeta and other details. Will your code fit in a comment? $\endgroup$ Dec 2, 2012 at 19:51

    $\begingroup$ Its rather simple. I got it years back I think it was a Mathematica example. Play[RiemannSiegelZ[2000 t], {t, 0, 5}, PlayRange -> {-20, 20}] $\endgroup$
