The Digital Signal Processing Laboratory (DSP Lab)
is set up in 1998 after Texas Instruments award the title of Texas Instruments DSP Elite Lab status to NTU. It is also the only Texas Instruments DSP Elite Lab in Singapore. The role of the TIDSP Elite Lab is to train engineers
and researchers in the advanced area of real-timeDSP implementation using the Texas Instruments state-of-the-art DSP processors. We have since trained more than 300 students since the inception of the Elite Lab and looking
forward to work closely with TI and other companies in training future manpower in embedded media processing. So far, we have conducted several high-profile workshops for Texas Instruments, Analog Devices, Philips, Activemedia,
The DSP Lab is also playing an important role to bring advanced DSP research work into practical realization. Over the past few years, the DSP lab has developed into a well-recognized lab in Singapore doing
applied signal processing projects for the industry. We have received and delivered several research contracts from companies like DaimlerChrysler (Germany), Singapore Technologies Kinetics, Texas Instruments (USA), Analog
Devices (USA), Excelpoint System, TechSource, and research agency like A*STAR. We have also been widely consulted in area in real-time DSP implementation and applications, audio and acoustics signal processing, and DSP
programming. Through this industry interaction, the value-added work carried out in the DSP Lab has constantly led to further research that combines fundamental and real-time DSP issues.
3D Audio Headphones
Developing a natural sound rendering headphone system with strategic-positioned emitters and advanced 3D audio signal processing techniques. Achieving personalized 3D audio automatically without any measurements or
training. Producing important sound cues to recreate a realistic perception of directional sound sources immersed with surround ambience.
With the strong growth of assistive and per- sonal listening devices, natural sound ren- dering over headphones is becoming a necessity for prolonged listening in multime-dia and virtual reality applications. The aim of
natural sound rendering is to naturally recreate the sound scenes with the spatial and timbral quality as natural as possible, so as to achieve a truly immersive listening experience. However, rendering natural sound
over headphones encounters many challenges. This tutorial article presents signal processing techniques to tackle these challenges to assist human listening.
Personal Assistive Listening System is developed using a unique and novel combination of parametric loudspeaker and conventional electro-dynamic loudspeakers developed by the NTU team. By using the combined sound
projection of the parametric and conventional loudspeakers, higher sound clarity at predefined frequencies (especially in speech recognition) can be heard by hearing impaired listeners. Personalized Assistive Listening
System allows normal hearing listeners and hearing-impaired listeners watching TV together without compromising everyone’s listening experiences.
Abating Urban Noise Through a Holistic approach of noise monitoring, analytic and control (MAC)
The main research objective of this project is to combine different enabling technologies developed by ADSC, I2R, and NTU to continuously monitor, analyze, and perform active noise control on aircraft, rail, and road
traffic noises affecting the liveable residential environment. With rapid urban development, the annoyance and dissatisfaction caused by excessive urban noise is familiar to almost all Singaporeans; the negative health
impact is less well known but is nonetheless very significant.
