Statistical Signal Processing Research Laboratory (SSPRL) and UT-Acoustic Laboratory (UT-AL) are focused on Audio DSP Algorithm Development and Hardware Implementation, respectively. Application specific audio DSP algorithms are delivered through the phases of conception, initiation, analysis, design, construction, testing, production/implementation and maintenance. The labs are located in the Erik Johnsson School of Engineering and Computer Science in the North building (ECSN) on the 4th floor and 2nd floor, respectively.
SSPRL is located on the 4th floor of the Erik Johnsson School of Engineering and Computer Science in the North building (ECSN 4.218). The Lab is equipped with 14 high-performance Intel i7 computers with flat, wide monitors, overhead projector, conference table, and study desks and book-shelves. All personal computers are connected to the UTD network with access to internet, library and periodical publications. They are equipped with Windows & Mac OS with MS Office, MathWorks’ MATLAB R 2015, NI’s LabVIEW, Adobe Audio, Visio, Eclipse IDE, OpenSL ES, Android Studio and complete software design and simulation packages. The lab provides research, study, and working environment for the PhD and MS research students. There are also 8 TI’sTMS320C/F5xxx and ‘6xxx DSP (EVM and DSK) platforms, as well as 2 TI’s MSP430, and 2 Microchip PIC Micro controller platforms. The SSPRL focuses on cutting edge algorithm development through conception, initiation, analysis, design, construction, testing and encourages cross-functional collaboration with other departments and research groups across UT Dallas. We encourage students and professionals to explore and engage in our audio/speech DSP research at SSPRL. Our notable alumnus have been contributing actively in audio DSP research in reputed companies such as Amazon, Cirrus Logic, Dolby, Garmin, Continental, Kopin, Broadcom, Zounds Hearing and in Academia.
UTAL is located on the 2nd floor of the Erik Johnsson School of Engineering and Computer Science in the North building (ECSN 2.314). The Lab is equipped with a test-bed mimicking the fMRI bore. The test-bed consists of an actual fMRI bore size, half-cylindrical tube, 8 high performance Microphones, preamplifiers, long shielded cables, and power supplies, 8 high-fidelity loud-speakers, function generators, digital oscilloscopes,5 high-speed, high-capacity state-of-art computers with 24 inch flat monitors, two 8 channel high-fidelity audio amplifiers, 6 monitor headphones /head-sets, 4 8-channel parallel ADC and 8-channel DAC board with 3Mega gate on-board FPGA, 4 Texas Instruments (TI) digital Audio/amplifier boards, 7 TI’s high-speed floating-point DSK platforms with associated software (Code Composer Studio), Adobe Audio software, National Instruments (NI) LabVIEW (graphical design) software package, 3 full-size and half-size manikins, and several analog filter design boards. The equipment also include 3 wireless microphones, 4 Ultrasound array of directional loudspeakers. There is also anechoic chamber and 8 hearing aid devices, and 3 Android smartphones. The UT-AL focuses on real-time algorithm development through hardware implementation, testing, production/implementation and maintenance and encourages interested undergraduate students to participate and to get them excited about Audio DSP Technologies across UT Dallas.
