Huge, fast developing community providing tons of libraries. SciPy provides plethora of methods for signal processing (granted, not that many and mature as Matlab). Mind though that SciPy, although one of the most important, is only one of hundreds that can help you in your endeavours. I found Aubio best for music analysis.

>>> import numpy as np >>> import scipy.signal as signal >>> import matplotlib.pyplot as plt >>> fs = 10e3 >>> N = 1e5 >>> amp = 2 * np . sqrt ( 2 ) >>> freq = 1270.0 >>> noise_power = 0.001 * fs / 2 >>> time = np . arange ( N ) / fs >>> x = amp * np . sin ( 2 * np . pi * freq * time ) >>> x += np . random . normal ( scale = np . sqrt ( noise_power ), size = time . shape )

Signal processing (scipy.signal): Provides implementations of many useful signal processing techniques, such as waveform generation, FIR and IIR ltering and multi-dimensional convolution. Interpolation (scipy.interpolate): Consists of linear interpolation functions and cubic splines in several dimensions. Matplotlib is a library of 2-dimensional plot-
