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
