scimpy 0.0.dev1

Speaker design and impedance measuring tool

Scimpy is an open-source, cross-platform loudspeaker design tool. Features include:

• Modeling speaker impedance, phase, SPL, and group delay from TS Parameters

• Measuring speaker impedance using your sound card as a signal generator and data acquisition system

• Extract TS parameters from measured results and downloaded ZMA files.

• Loudspeaker cabinet design: the tool will calculate speaker performance (SPL and group delay) for sealed and vented box designs. Will calculate “optimal” cabinet dimensions for traditional speaker alignments (B2 closed box, QB4-B4-C4)

• A complete book covering speaker design theory

Scimpy is short for “Sound Card Impedance Measurements in PYthon”

General Python Requirements:

Python 2 or 3, scipy, numpy, pyaudio, matplotlib, pandas and either pyqt4 or pyside

Debian/Ubuntu development environment & installation:

sudo apt-get install python3-scipy python3-pyaudio python3-matplotlib python3-pyside python3-pandas
python3 setup.py install

Windows Python Environment & Scimpy Installation:

Full install (LARGE), comes with spyder IDE and many other python packages

install anaconda (https://www.continuum.io/downloads), open anaconda console and then in the anaconda console run “pip install pyaudio”.

If you want more control over the sound card, you can use a version of pyaudio built with more APIs available. Download pyaudio from: http://www.lfd.uci.edu/~gohlke/pythonlibs/ then open the anaconda console and install pyaudio with “pip install PyAudio-0.2.9-cp35-none-win_amd64.whl” replacing PyAudio-0.2.9-cp35-none-win_amd64.whl with the name of the file you downloaded.

Minimal install:

Install miniconda (32bit, even if you have 64 bit - makes things easier) from: http://conda.pydata.org/miniconda.html

Open Windows PowerShell (Start Menu, search for “Windows PowerShell”) and type the following commands:

conda update conda
conda install matplotlib scipy numpy
pip install pyaudio
cd LOCATION_WHERE_SCIMPY_WAS_DOWNLOADED
python run.py

have fun!

How to build Windows binaries

PyInstaller works. First install pyinstaller:

pip install pywin32 pyinstaller
conda install setuptools=19.2

(downgrading setuptools: https://github.com/pyinstaller/pyinstaller/issues/1781)

The run

pyinstaller -F run.py

to get a single executable in dist/
