NU-Tech: Implementing DSP Algorithms in a Plug-in Based Software Platform for Real time Audio Applications
This work presents a novel software platform called NU-Tech to implement real-time DSP algorithms in multi-channel scenarios. Running on a common PC, the overall framework is based on a plug-in architecture, allowing the user to connect specific blocks, operating as DSP algorithms, within the available graphical design environment. These blocks, namely NUTs' (NU-Tech Satellites), have to be previously written in C++. A strict control over latency times is insured by a proper interface to the hardware layer of the PC sound card. It turns out that NU-Tech is well suited for development, real-time debugging and fine tuning of DSP algorithms. As further application, it fulfils the role of DSP operating core of new stand-alone programs preventing the user to develop them from scratch. Some examples are provided to show the effectiveness of the idea.
