Direct Audio Playback (DAP)
Dr. Yonglei Tao, firstname.lastname@example.org
The goal of this project is to provide playback capability using a laptop PC of an audio stream which is being sampled by a remote device. The device in this case is a flight data recorder which samples and encodes cockpit audio into a G.726 audio stream for recording into crash protected memory. This project allows for the user to plug in a thin client PC to the device (via ethernet) and listen to the audio data as it is being recorded. This is achieved through the use of a web page and ActiveX control that once uploaded to the PC, allows the user to initiate the transmission of the audio stream (using RTP) from the device to the PC. The stream is then buffered into the PC?s RAM and played through the PC speaker system using Direct X / Direct Sound drivers.
