wavio
wavio is a Python module that defines two functions:
readwavreads a WAV file and returns the sampling rate, sample width (in bytes), and a numpy array containing the data.writewav24writes a numpy array to a 24 bit WAV file.
The module uses the wave module in Python's standard library, so it has the
same limitations as that module. In particular, it does not support compressed
WAV files.
The wavio module provides an alternative to the SciPy module scipy.io.wavfile.
As of version 0.15.0 of scipy, the functions in scipy.io.wavfile do not support
24 bit sample widths. The function in this module, wavio.readwav, can read
24 bit files. When the sample depth is 24 bits, the data is returned in a 32 bit
numpy array.
wavio has been tested with Python versions 2.7 and 3.4. It will likely
work with older versions.
wavio depends on numpy (http://www.numpy.org). It has been tested with versions 1.8.1
and 1.9.0, and will likely work with older versions.
