sndhdr — Determine type of sound file
Source code: :source:`Lib/sndhdr.py`
The sndhdr provides utility functions which attempt to determine the type of sound data which is in a file. When these functions are able to determine what type of sound data is stored in a file, they return a namedtuple(), containing five attributes: (filetype
, framerate
, nchannels
, nframes
, sampwidth
). The value for type indicates the data type and will be one of the strings 'aifc'
, 'aiff'
, 'au'
, 'hcom'
, 'sndr'
, 'sndt'
, 'voc'
, 'wav'
, '8svx'
, 'sb'
, 'ub'
, or 'ul'
. The sampling_rate will be either the actual value or 0
if unknown or difficult to decode. Similarly, channels will be either the number of channels or 0
if it cannot be determined or if the value is difficult to decode. The value for frames will be either the number of frames or -1
. The last item in the tuple, bits_per_sample, will either be the sample size in bits or 'A'
for A-LAW or 'U'
for u-LAW.
- sndhdr.what(filename)
Determines the type of sound data stored in the file filename using whathdr(). If it succeeds, returns a namedtuple as described above, otherwise
None
is returned.Changed in version 3.5: Result changed from a tuple to a namedtuple.
- sndhdr.whathdr(filename)
Determines the type of sound data stored in a file based on the file header. The name of the file is given by filename. This function returns a namedtuple as described above on success, or
None
.Changed in version 3.5: Result changed from a tuple to a namedtuple.
