QAcousticCamera
Scanning holographic acoustic camera based on lock-in detection of the signal from a microphone that is scanned across the field of view by an Arduino-driven polargraph. This illustration of the software interface shows the phase of a 5 kHz sound wave from a stereo speaker, including reflections from nearby surfaces.

Installation
pip install QAcousticCamera
All dependencies, including QInstrument and QPolargraph, are installed automatically. A Qt binding such as PyQt6 must also be present.
Usage
# Connect to hardware instruments
python QAcousticCamera.py
# Development/testing without hardware
python QAcousticCamera.py --fake
# Load a previously saved data file on startup
python QAcousticCamera.py --read docs/demo.csv
Or, if installed via pip:
qacousticcamera [--fake] [--read FILE]
Dependencies
- QInstrument: Qt-based scientific instrument framework
- QPolargraph: polargraph scanner
- pyqtgraph: real-time scientific graphics
- qtpy: Qt binding abstraction (PyQt5, PyQt6, or PySide6)
- numpy, pandas, scipy
