14.10 sndhdr -- Determine type of sound file
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 tuple (type, sampling_rate,
channels, frames, bits_per_sample). 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.
-
Determines the type of sound data stored in the file filename
using whathdr(). If it succeeds, returns a tuple as
described above, otherwise
Noneis returned.
-
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 tuple as described above on success, or
None.
