"""Stuff to parse WAVE files. Usage. Reading WAVE files: f = wave.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). When the setpos() and rewind() methods are not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: 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' for linear samples) getcompname() -- returns human-readable version of compression type ('not compressed' linear samples) getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- returns None (for compatibility with the aifc module) getmark(id) -- raises an error since the mark does not exist (for compatibility with the aifc module) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell() and the position given to setpos() are compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing WAVE files: f = wave.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple) -- set all parameters at once tell() -- return current position in output file writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header. The close() method is called automatically when the class instance is destroyed.
