The only visual customization available for the Megaphone players is to choose between our light and dark themes. You can also create a custom web player and use the Megaphone API to pull in audio files to your player. Read our documentation for the API here.
Our players are iFrames that need to be embedded by the website manager, who can copy the code into each page's HTML. The best place to place our code is right before the closing </body> tag. Detailed instructions below.
For any suggestions to the standard player, please add an idea or vote on previous feature requests using our Megaphone Suggestion Box.
