14.5.1 Wave_read Objects
Wave_read objects, as returned by open(), have the
following methods:
- close ()
-
Close the stream, and make the instance unusable. This is
called automatically on object collection.
- getnchannels ()
-
Returns number of audio channels (
1 for mono, 2 for
stereo).
- getsampwidth ()
-
Returns sample width in bytes.
- getframerate ()
-
Returns sampling frequency.
- getnframes ()
-
Returns number of audio frames.
- getcomptype ()
-
Returns compression type (
'NONE' is the only supported type).
- getcompname ()
-
Human-readable version of getcomptype().
Usually
'not compressed' parallels 'NONE'.
- getparams ()
-
Returns a tuple
(nchannels, sampwidth, framerate,
nframes, comptype, compname), equivalent to output
of the get*() methods.
- readframes (n)
-
Reads and returns at most n frames of audio, as a string of bytes.
- rewind ()
-
Rewind the file pointer to the beginning of the audio stream.
The following two methods are defined for compatibility with the
aifc module, and don't do anything interesting.
- getmarkers ()
-
Returns
None.
- getmark (id)
-
Raise an error.
The following two methods define a term ``position'' which is compatible
between them, and is otherwise implementation dependent.
- setpos (pos)
-
Set the file pointer to the specified position.
- tell ()
-
Return current file pointer position.
