# pydvma

A Python package for dynamics and vibration measurements and analysis.

## About pydvma

This is a modular library for data-measurement and analysis in the context of dynamics and vibration, for use in student laboratory experiments as well as for research projects.

A high-level interface allows straightforward application for common use-cases and a low-level interface provides more control when needed.

The aim is for a library that is simple to use and simple to maintain. It is not a full-featured GUI, but when used in conjunction with Jupyter Notebooks it is intended to provide the best of both worlds: interactive tools for specific tasks and command line interface for customisation.

## Getting started

### Dependencies

On Windows: TBC

On Mac OS X: install PortAudio. If you use Homebrew, just run this: `shell $ brew install portaudio `

On Linux: TBC

### Installing pydvma

Install using: ` pip install pydvma --upgrade `

Or clone this repository and install using:

` python setup.py install `

To get started, within a Jupyter Notebook or Python command line:

`python import pydvma as dvma settings = dvma.MySettings() osc = dvma.Oscilloscope(settings) `

## Roadmap

At present the library has basic functionality for:

• logging data using sound cards

• computing frequency domain data

• saving and plotting data

The plan is to include the following functionality:

• logging data using National Instrument DAQs

• computing and viewing sonograms / spectrograms (time-frequency plots)

• computing transfer functions

• modal analysis tools (e.g. circle fitting)

• extend the range of hardware that can be accessed from this library
