An Audio and Video class for ruby
This code can be used for both audio and video file. Please give credit for using it. you can modify the code as much as you want. as you can see you edit it so that the files are used from any folder by changing this variables
DIR = "Audio" @movie_name = "Movies/"+name To use the audio, you simply do myAudio = Audio.new() #create an instance myAudio = Audio.new(filename) #you can use the file with and without the extension name if you use decide to use the instance without the filename, you can simple call myAudio.audio_open(filename) and the myAudio.audio_play() #==============================================================================
# ** Audio

class Audio
