Audio- A Custom Player with Designed Control Box

Written by @m_k_amin 6 June 2013

HTML5 default audio player box has not complete options and buttons while it supports them in general; so the developers themselves must make a Control Box for their desired audio player. In fact, if you are not satisfied with the default control box, you can make your own! This code, which uses both HTML5 and JavaScript, is an example of control box with desired buttons for the HTML5 audio element. It has six buttons in order to play, pause, volume up, volume down, playback speed (playback rate) up and down. There are also some textboxes for showing the status of each option. Note that the volume and playback rate can vary in a fixed predefined range, but the step of changing is up to you. Enjoy!
