Sound and speech synthesis
Voice multicasting (Voice over IP)
Voice over IP (VOIP) is a common component of communications technology.
It has been implemented to varying degrees of success. You would
be charged with creating a new form of VOIP that would scale to
fit available bandwidth and produce telephone quality for multiple
connections for highest bandwidth connections. Your new technology
should not be tied to a particular platform.
Prerequisites: Networks, Compression and an interest in music.
Spatial acoustic rendering
Being able to place sound in a 3D space impacts greatly on your
ability to simulate reality. This project will see you challenge
the problem creating, quality spatial audio environments for virtual
or filmed immersive realities.
Spatial audio is sound that has been processed to give the listener
a sense of the location of a virtual sound source and the characteristics
of a virtual listening space. True binaural spatial audio, when
presented over headphones, appears to come from a particular point
in the space outside of the listener's head. This is different
from ordinary recorded stereo, which is generally restricted to
a line between the ears when listened to with headphones. Although
several stand-alone prototype solutions have been developed, most
spatial audio systems provide little in the way of environmental
modeling, synchronization, or network support.
“
A spatial audio server is to be developed with the following characteristics:
network control interfaces, support for multiple clients, support
for simultaneous playback of multiple sounds, prioritization of
requests for limited resources, and mechanisms for synchronizing
client applications with an audio stream. The server must also
include mechanisms for the choreography of moving sound sources,
and, ideally, an acoustic renderer for modelling the listening
environment automatically.” (http://www.cc.gatech.edu/gvu/multimedia/spatsound/NetAudio.html)
