library2.1.6pypypiunverified

A library for signal processing algorithms, originally developed at MongoDB, including peak detection using the 'peak_shapes' algorithm and related utilities. Current version 2.1.6 requires Python <3.12,>=3.11. Maintained by MongoDB.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

peak_shapes

✓ from signal_processing_algorithms import peak_shapes

✗ from signal_processing_algorithms.peak_shapes import peak_shapes

Detect peaks in a sine wave using the peak_shapes algorithm.

from signal_processing_algorithms.peak_shapes import peak_shapes from signal_processing_algorithms.peak_shapes import Signal import numpy as np signal = Signal(np.sin(np.linspace(0, 10, 1000))) results = peak_shapes(signal, threshold=0.5) print(results)

Debug

Known issues

gotchaThe import path uses underscores: `signal_processing_algorithms` not `signal-processing-algorithms`. The hyphenated name is only for pip install.

fix

Use `from signal_processing_algorithms.peak_shapes import peak_shapes`

affects: all

deprecatedThe `peak_shapes` function has been renamed to `find_peaks` in version 2.0.0. The old name still works but may be removed in future.

fix

Use `from signal_processing_algorithms.peak_shapes import find_peaks`

affects: >=2.0.0

gotchaThe `Signal` class requires a numpy array. Passing a list will raise a TypeError.

fix

Convert list to numpy array: `signal = Signal(np.array([...]))`

affects: all
