The !trumpet is software synthesis system controlled from, and playing back through, a trumpet.  It is not an electronically extended trumpet: the player produces no acoustic sounds by blowing through the mouthpiece. Instead, breath pressure and valve movement on the brass instrument are read by an embedded Arduino microcontroller  and sent to a laptop, where the data is mapped onto various parameters in synthesis software; the resulting electronic sound is returned to the trumpet, where it plays through a loudspeaker inside the bell, and is further processed acoustically by valve position (changes in the length of tubing filter the speaker output), movement of a plunger mute (wah-wah style filtering), and orientation of the instrument in space (panning).

To improve the productivity and quality of software development, a software synthesis shell called SOFTEXSHELL has been developed. SOFTEXSHELL is a tool kit with a transformation system based on a term rewriting system, a language DSL/C++ for defining transformation rules as well as a specification language for a specific software model, and a rule verification system which supports development of correct transformation rules. The system is designed to provide an environment which enables a broad range of software engineers to construct software synthesis systems for their domains. To evaluate how effectively SOFTEXSHELL does this, a software synthesis system for switching scenario software was developed by two switching software specialists without prior software synthesis experience. After a four-month prototype development period, a practical software synthesis system for switching service software was developed in eight months. The developed software synthesis system, SOFTEX/EX, has been utilized for developing six switching systems. Generated programs, including 272,000 steps in total, have been in daily operation. Based on the development process and developed system results, we conclude that SOFTEXSHELL enables software engineers, without prior software synthesis experience, to develop useful and efficient software synthesis systems.

Chaosynth is a cellular automata-based granular synthesis system whose capabilities for producing unusual complex dynamic sounds are limitless. However, due to its newness and flexibility, potential users have found it very hard to explore its possibilities as there is no clear referential framework to hold on to when designing sounds. Standard software synthesis systems take this framework for granted by adopting a taxonomy for synthesis instruments that has been inherited from the acoustic musical instruments tradition, i.e. woodwind, brass, string, percussion, etc. Sadly, the most interesting synthesised sounds that these systems can produce are simply referred to as effects. This scheme clearly does not meet the demands of more innovative software synthesizers. In order to alleviate this problem, we propose an alternative taxonomy for Chaosynth timbres. The paper begins with a brief introduction to the basic functioning of Chaosynth. It then presents our proposed taxonomy and ends with concluding comments. A number of examples are provided on this volume's Organised Sound CD.

Aims: Normally, the temperature increase of individuals leads to the possibility of getting a type of disease, which might be risky to other people such as coronavirus. Traditional techniques for tracking core-temperature require body contact either by oral, rectum, axillary, or tympanic, which are unfortunately considered intrusive in nature as well as causes of contagion. Therefore, sensing human core-temperature non-intrusively and remotely is the objective of this research. Background: Nowadays, increasing level of medical sectors is a necessary targets for the research operations, especially with the development of the integrated circuit, sensors and cameras that made the normal life easier. Methods: The solution is by proposing an embedded system consisting of the Arduino microcontroller, which is trained with a model of Mean Absolute Error (MAE) analysis for predicting Contactless Core-Temperature (CCT), which is the real body temperature. Results: The Arduino is connected to an Infrared-Thermal sensor named MLX90614 as input signal, and connected to the LCD to display the CCT. To evaluate the proposed system, experiments are conducted by participating 31-subject sensing contactless temperature from the three face sub-regions: forehead, nose, and cheek. Conclusion: Experimental results approved that CCT can be measured remotely depending on the human face, in which the forehead region is better to be dependent, rather than nose and cheek regions for CCT measurement due to the smallest

For a spatial audio reproduction in the context of augmented reality, a position-dynamic binaural synthesis system can be used to synthesize the ear signals for a moving listener. The goal is the fusion of the auditory perception of the virtual audio objects with the real listening environment. Such a system has several components, each of which help to enable a plausible auditory simulation. For each possible position of the listener in the room, a set of binaural room impulse responses (BRIRs) congruent with the expected auditory environment is required to avoid room divergence effects. Adequate and efficient approaches are methods to synthesize new BRIRs using very few measurements of the listening room. The required spatial resolution of the BRIR positions can be estimated by spatial auditory perception thresholds. Retrieving and processing the tracking data of the listener’s head-pose and position as well as convolving BRIRs with an audio signal needs to be done in real-time. This contribution presents work done by the authors including several technical components of such a system in detail. It shows how the single components are affected by psychoacoustics. Furthermore, the paper also discusses the perceptive effect by means of listening tests demonstrating the appropriateness of the approaches.
