ezmsg-sigproc
Signal processing primitives for the ezmsg message-passing framework.
Features
- Filtering - Chebyshev, comb filters, and more
- Spectral analysis - Spectrogram, spectrum, and wavelet transforms
- Resampling - Downsample, decimate, and resample operations
- Windowing - Sliding windows and buffering utilities
- Math operations - Arithmetic, log, abs, difference, and more
- Signal generation - Synthetic signal generators
- More! Brows the API documentation for more details.
All modules use AxisArray as the primary data structure for passing signals between components. The default data backend is NumPy, but other backends are supported via the Array API such as CuPy and MLX.
Component discovery
This package registers its Units and Collections in the ezmsg.components
entry-point group. Names are qualified by extension (for example,
sigproc.ButterworthFilter); values point directly to the defining class.
Generic base classes and processor-only implementations are not registered.
from importlib.metadata import entry_points
components = {ep.name: ep for ep in entry_points(group="ezmsg.components")}
component_type = components["sigproc.ButterworthFilter"].load()
Enumerating entry points reads installed package metadata without importing
component modules. Calling .load() imports the selected component and may
raise if a runtime dependency is unavailable; it does not instantiate the Unit.
Consumers should retain unavailable entries and report their load errors.
Use the execution environment's Python interpreter to discover its components.
When adding a public component, add its entry point in pyproject.toml and
reinstall the package (including editable installs) to refresh the metadata.
