License: BSD URL: https://github.com/WarrenWeckesser/wavio Source0: https://mirrors.nju.edu.cn/pypi/web/packages/32/94/92ea8799b0770cf5dd8e5424a47fd9f0465ec6e9f3c5837af4fb7ad72ee3/wavio-0.0.7.tar.gz BuildArch: noarch Requires: python3-numpy %description ``wavio`` is a Python module that defines two functions: * ``wavio.read`` reads a WAV file and returns an object that holds the sampling rate, sample width (in bytes), and a numpy array containing the data. * ``wavio.write`` writes a numpy array to a WAV file, optionally using a specified sample width. The functions can read and write 8-, 16-, 24- and 32-bit integer WAV files. The module uses the ``wave`` module in Python's standard library, so it has the same limitations as that module. In particular, the ``wave`` module does not support compressed WAV files, and it does not handle floating point WAV files. When floating point data is passed to ``wavio.write`` it is converted to integers before being written to the WAV file. ``wavio`` requires Python 3.7 or later. ``wavio`` depends on numpy (http://www.numpy.org). NumPy version 1.19.0 or later is required. The unit tests in ``wavio`` require ``pytest``. The API of the functions in ``wavio`` should not be considered stable. There may be backwards-incompatible API changes between releases. *Important notice* In version 0.0.5, the data handling in ``wavio.write`` has been changed in a backwards-incompatible way. The API for scaling the input in 0.0.4 was a flexible interface that only its creator could love. The new API is simpler, and it is hoped that it does the right thing by default in most cases. In particular: * When the input data is an integer type, the values are not scaled or shifted. The only change that might happen is the data will be clipped if the values do not fit in the output integer type. * If the input data is a floating point type, ``sampwidth`` must be given. The default behavior is to scale input values in the range [-1.0, 1.0] to the output range [min_int+1, max_int], where min_int and max_int are the minimum and maximum values of the output data type determined by ``sampwidth``. See the description of ``scale`` in the docstring of ``wavio.write`` for more options. Regardless of the value of ``scale``, the float input 0.0 is always mapped to the midpoint of the output type; ``wavio.write`` will not translate the values up or down. * A warning is now generated if any data values are clipped. A parameter allows the generation of the warning to be disabled or converted to an exception. Example ~~~~~~~ The following code (also found in the docstring of ``wavio.write``) writes a three second 440 Hz sine wave to a 24-bit WAV file:: import numpy as np import wavio rate = 22050 # samples per second T = 3 # sample duration (seconds) n = int(rate*T) # number of samples t = np.arange(n)/rate # grid of time values f = 440.0 # sound frequency (Hz) x = np.sin(2*np.pi * f * t) %package -n python3-wavio Summary: A Python module for reading and writing WAV files using numpy arrays.
