No longer are cell phone voice band audio specifications sufficient. Support must be available for high quality consumer electronics oriented services and specifications. The types of audio devices in cell phones has expanded from the simple microphone, voice band codec, and speaker used in speech only cell phones to sophisticated collections of audio sources, various decoder playback devices, multiple audio output devices, and the necessary audio subsystem structures to tie them altogether in a sensible fashion. That means more different kinds of audio sources and standards, data formats, and signal levels to deal with.
