Distributed Computing Based Streaming and Play of Music Ensemble Realized Through TMO Programming

An adaptive multi-channel audio-play system with sound-source relocation capabilities

“…Each player node, i-th node, can adjust the playback-timing of each sound packet and compensate the attenuation by reflecting the distance from itself to the listener, d i , as follows [ where TD i is the playback delay, d max is the maximum playerto-listener distance, VOL i is the output volume in dB, and VOL ref is the reference output volume for all the player nodes. The basic techniques adopted for establishment of a highprecision global time base are not discussed here due to the space limit and are referred to [1]. Also, the exploitation of global time and the TCoDA principle is facilitated in highly cost-effective forms by the TMO programming scheme and associated tools [6,7,8] but are not discussed here.…”

“…This paper describes a recently developed adaptive multichannel audio-play system (AMAS), which is an extension of the previous distributed sound system (DSS) [1]. It exploits the principle of global-time-based coordination of distributed computing actions (TCoDA) [2], and possesses the capability of creating the effects of specified instruments positioned differently from the positioning that existed at the time of original recording.…”

Structuring of an Adaptive Multi-channel Audio-Play System Based on the TMO Scheme

“…The adaptive multi-channel audio-play system (AMAS), which is a refinement and expansion of the earlier developed distributed sound system (DSS) [2], demonstrates a new attractive approach for rendering multi-channel music. As depicted in Fig.…”

“…In many networked real-time embedded computing such as this digital music ensemble application, exploiting the principle of glottal-Timebased Coordination of Distributed computing Actions (TCoDA) is of fundamental importance [2,5]. To enable such TCoDA exploitation in efficient manners and also to ease the maintenance and expansion of the software of AMAS, we adopted the Time-triggered Message-triggered Object (TMO) programming and specification scheme [8,9,10] for implementing the software.…”
