چکیده
Signal processing algorithms are the hidden components in audio processor that converts received acoustic signal into electrical impulses while maintaining as much relevant information possible. should be smart enough to mimic functionality of external, middle and inner-ear provide cochlear implant (CI) user with a hearing experience natural Modern sound strategies based on continuous interleaved sampling (CIS) strategy proposed by B. Wilson 1991, which provided envelope over several intracochlear electrodes. The CIS brought significant gains speech perception. Translational research activities MED-EL resulted further improvements understanding noisy environments well enjoyment music not only coding CIS-based information, but also representing temporal fine structure stimulation patterns apical channels. Further developments include “complete coverage” made possible deep insertion electrode, elaborate front end processing, anatomy fitting (ABF), triphasic pulse instrumental suppression facial nerve stimulation, bimodal delay compensation allowing unilateral CI users aids contralateral ear. large number hardware might exemplified RONDO, world's first single unit 2013. This article covers milestones translational around topic took place association MED-EL.

Digital Signal Processors for real-time audio processing
We analyze the requirements for digital signal processors used in audio applications. Methods for assessing the real computing power expected from them are presented. Proper requirements for a real-time development platform are also described. Code development tools are also included. Finally a review of common processors is done according to those criteria.
متن کاملPython For Audio Signal Processing
This paper discusses the use of Python for developing audio signal processing applications. Overviews of Python language, NumPy, SciPy and Matplotlib are given, which together form a powerful platform for scientific computing. We then show how SciPy was used to create two audio programming libraries, and describe ways that Python can be integrated with the SndObj library and Pure Data, two exis...
متن کاملRadar Signal Processing with Graphics Processors (GPUs)
Radar Signal Processing algorithms place strong real-time performance demands on computer architectures. These algorithms do however have an inherent data-parallelism that allows for great performance on massively parallel architectures, such as the Graphics Processing Unit (GPUs). Recently, using GPUs for other than graphics processing has become a possibility through the CUDA and OpenCL (Open...
متن کاملAccelerating Signal Processing Algorithms Using Graphics Processors
There is increased interest in the use of graphics processing units (GPUs) for general purpose computation. This is because GPUs are almost two orders of magnitude faster in terms of floating point throughput compared to conventional CPUs. In this paper we investigate the use of graphics processing units for accelerating signal processing algorithms, specifically FIR filters and the FFT. We des...
