Python (3.6+) routines for analyzing signals. Some of the functions include:

• Calculating Short-Time Fourier Transform
• Smoothing a signal
• Plotting an STFT's spectrogram
• Calculating the peak hold of an STFT in the freq domain
• Plotting the peak hold of an STFT

The above functions are handy when analyzing signals recorded in the time domain, such as using a TEAC LX-10 data recorder, and seeing the frequency spectrum for Electromagnetic Compatibility (EMC) analyses.

You can install siganalysis either via the Python Package Index (PyPI) or from source.

To install using pip:

$ pip install siganalysis
