PyPlotAudio is a graphical audio analyzer based on QT5, soundfile, numpy and scipy.
It was developed using Python 3(.9.10), however, it should work on later versions, at least up to the latest 3.9.x. PyQt5 doesn't work with python 3.10 and up, as of today (December 2022).
The dependencies are listed in the requirements.txt and can be installed with pip.
WAV files, test signals and sound device streams can be read and analyzed in real time. The user is able to tweak a few parameters and observe their influence in the spectrum straight away.
The GUI is done on PyQt5 Designer. For converting into the respective python file:
pyuic5 analyzer.ui -o gui.py
You might want to create a virtual environment, activate it and run it from there
python -m venv ven
venv/Scripts/activate
pip install -r requirements.txt
python src/AudioAnalyzer.py- Overlap
- Stretch plot and other widgets when resizing a window
- Better soundcard handling, as now only channel 0 is used
