sumpf 0.15

A signal processing package with a focus on acoustics

The SuMPF package provides some classes, that implement offline (non-realtime) signal processing functionalities. SuMPF is being developed with a focus on acoustics, but it might be applicable for the analysis of other time series data as well.

Here is a brief example of SuMPF in action:

>>> import sumpf
>>> noise = sumpf.GaussianNoise(mean=0.0,
...                            standard_deviation=1.0,
...                            sampling_rate=48000.0,
...                            length=2 ** 14)
>>> filter_ = sumpf.ButterworthFilter(cutoff_frequency=1000.0, order=4, highpass=True)
>>> filtered = noise * filter_
>>> spectrum = filtered.fourier_transform()

Installation

The SuMPF package requires Python version 3.7 or later. Most features should be available with Python 3.6 as well.

pip3 install sumpf
