wavio
wavio
is a Python module that defines two functions:
readwav
reads a WAV file and returns the sampling rate, sample width (in bytes), and a numpy array containing the data.writewav24
writes 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.
