The sound card anno 2010, is an ubiquitous part of almost any personal computing system; what was once considered a high-end, CD-quality audio fidelity, is today found in most common sound cards. The increased presence of multichannel devices, along with the high sampling frequency, makes the sound card desirable as a generic interface for acquisition of analog signals in prototyping of sensor-...

In classical routing protocols, geographical distances/locations are typically used as the metric to select the best route, under the assumption that shorter distances exhibit lower energy consumption and nodes within the communication range of the sender can receive packets with a certain success probability. However, in underwater acoustic sensor networks (UASNs), sound propagation in the oce...

Wireless sensor networks are suitable to gain context awareness for indoor environments. As sound waves form a rich source of context information, equipping the nodes with microphones can be of great benefit. The algorithms to extract features from sound waves are often highly computationally intensive. This can be problematic as wireless nodes are usually restricted in resources. In order to b...

Camera recorders in general will continue to record continuously without stopping and this take up storage space. This is deemed less effective because of its limited capacity also terms security, the recorded information very vulnerable. Therefore, study, a portable recording camera system was designed using multi sensors integrated raspberrypi with server then results automatically be sent fo...

A transmission-line acoustic metamaterial is an engineered, periodic arrangement of relatively small unit-cells, the acoustic properties of which can be manipulated to achieve anomalous physical behaviours. These exotic properties open the door to practical applications, such as an acoustic leaky-wave antenna, through the implementation of radiating channels along the metamaterial. In the trans...

Specter combines music information retrieval (MIR) with sound spatialization to provide a simple, yet versatile environment to experiment with sound spatialization for music composition and live performance. Through various interfaces and sensors, users may position sounds at arbitrary locations and trajectories in a three-dimensional plane. The system utilizes the JythonMusic environment for s...
