sndhdr — Determine type of sound file
Source code: Lib/sndhdr.py
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: (
sampwidth). The value for type indicates the data type and will be one of the strings
'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.
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
Changed in version 3.5: Result changed from a tuple to a namedtuple.
