Fourier transform of sampled data The issue is that my actual data has a sample frequency of 48000Hz and that I can't find any option to tell Fourier that. |

Fourier transform of sampled data Figured that as well just this instant. The only issue is still to incorporate the sampling frequency when using Fourier. I will change the question accordingly. |

Issue with ListDensityPlot when using logarithmic scale 1-click-hoster aren't what they were used to be anymore... until I find another one that actually works you can try dl.dropboxusercontent.com/u/74966785/SaschaData.zip |

Only perform a symbolic differentiation once Have you tried to create a non global variable inside your function that stores the derivative? You could then use replacement rules to call upon the derivative. |

Export to pdf from Mathematica using Greek characters I recommend using .eps whenever possible |

Graphical representation of a moving sound source unfortunately they want a .pdf-file and I suspect just for the sake of printing it on top of that. (And I currently don't know if the hassle of getting 3D data from Mathematica to .pdf is worth the hassle anyway, meaning that I suspect there to be some kind of quality issue, color, aliasing etc.) |

Graphical representation of a moving sound source I added a picture of the microphone arrangement. I guess they are pretty directional just due to their form factor:) |

Graphical representation of a moving sound source Looking at your graphic I came to think it would be awesome for actual presentation to print a banner with the data in 2D and then wrap it up to get a cylinder barrel of paper much like your plot. You could then stick your head in the ring and view the data in relation to its actual physical position. Sad that I don't have to present it though (it's only a report to be handed in) :) |

Graphical representation of a moving sound source I am sorry but I have to disappoint you, it's rather far off. They were just a few centimetres apart, but as illustrated in the sketch above they are positioned with a 90° offset. I have a second .wav- file obtained with a KEMAR dummy-head that I will post tomorrow if that is deemed interesting. There the amplitude difference is not as characterising as in the measurement with two standard microphones. However the time lag is more apparent as far as I can tell from just looking at it (didn't try your plot on it yet). |
