Audio::File::Type(3pm) User Contributed Perl Documentation Audio::File::Type(3pm) NAME
Audio::File::Type - represents an audio filetype DESCRIPTION
An instance of an object inherited from Audio::File::Type is returned by the constructor of Audio::File. This object currently provides access to the audio files information like its audio properties (bitrate, sample rate, number of channels, ...) and the data stored in the files tag, but also providing access to the raw audio data and other information should be easy to be implemented. METHODS
new Constructor. In fact you don't need to use it. Please use Audio::File which will call the appropriate constructor corresponding to the files type. init This method will be called by the constructor. It's empty by default and should be overwritten by inheriting subclasses to initialize themselfes. name Returns the name of the audio file. is_readable Checks whether the file is readable or not. At the moment it's only used by the constructor, but it will be more usefull with later versions of Audio::File. is_writeable Checks whether the file is writeable or not. At the moment you'll probably don't need to call this method, but it'll be more usefull as soon as changing the audio file is implemented. tag Returns a reference to the files tag object. See the documentation of Audio::File::Tag to learn about what the tag object does. audio_properties Returns a reference to the files audio properties object. See the documentation of Audio::File::AudioProperties to get information about what the audio properties object does. save Saves the audio file. This is not yet implemented but it should remember me to do it at some time.. :-) type Returns the files type. TODO
implement changing the file SEE ALSO
