This provides tests and doc-generating scripts for Signalsmith Audio's DSP Library.
This should be placed as a sub-directory of the main DSP library (e.g. doc/).
Tests are in tests/, and (where possible) they test the actual audio characteristics of the tools (e.g. frequency responses and aliasing levels).
make tests
You can compile/run just specific groups of tests, based on the subfolders in tests/, e.g.:
make test-delay
Some of the tests write results to CSV files (as well as verifying them). Any Python files in the tests/ (sub-)directory are run if the tests succeed, and these generally plot the CSV results into graphs.
Both the tests and the Python scripts are run from the out/analysis/ directory.
You'll need SciPy/NumPy and Matplotlib, and ffmpeg if you want to create some supplemental animations:
make analysis-animations
