Summary
In this chapter, you learned about playing tones and sampled audio in MIDP. It utilized a subset
of the Mobile Media API (MMAPI), the Audio Building Block (ABB). It is based on Player s that
know how to render audio data and implicit protocol objects that understand how to transport
audio data to the Player . Aside from optional and flexible support for sampled audio, the ABB
also includes a tone sequence player. In MMAPI, the same familiar Player and Control API
model is used to display video and to snap pictures on a camera phone. Your MIDlets can now
benefit from the excitement of music, sampled audio, and recorded video.
