owlfft 0.0.2

Wrap scipy fft and numpy loadtxt within a simple GUI

This package implements a simple GUI to calculate real positive Fourier transforms from data stored in a .csv file, e.g., the recording data of an accelerometer. It aimts to be an educational resource for the structural dynamics course at the Barcelona School of Civil Engineering.

Installation

On the commandline, type the following command:

pip install owlfft

After that, you can call the package as a module from any location, like

python -m owlfft

Alternatively, you can download the file owlfft.py into a place of your choice and make sure all the dependencies are installed,

pip install numpy scipy matplotlib pyqt5 superqt

and then, run the python script:

python owlfft.py

Usage

The above window will be opened. It allows to select a .csv file and to specify how to read it (custom delimiter, columns where to read data, etc.). There are also two range sliders to trim the time and the frequency domains. Finally, a cursor is added to the FFT spectrum plot.

Why an owl?

Because the python project must be unique, because the author likes birds and because the name is short.
