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).

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.

The following two methods are defined for compatibility with the aifc module, and don't do anything interesting.

The following two methods define a term ``position'' which is compatible between them, and is otherwise implementation dependent.
