Audio When the Internet started it was a text-based communication. The development into the World Wide Web and development tools and browsers means the Internet is capable of handling graphics, stills, illustrations, audio and animation and video. The capabilities of modems have expanded to the extent that quality FM (frequency modulated audio) is now available from many sites. This of course comes with the proviso that you have at your receiving site the modem and sound capability to take advantage of these transmitting sites.
