Modulated Complex Lapped Transform (MCL T) is a complex extension of Modulated Lapped Transform (MLT), which is widely used for audio compression. Being a complex transform, MCLT incorporates phase information in it, unlike MLT. Hence it can be used for applications that require complex sub-band processing. Several algorithms have been published to process signals in the MCLT domain in a fast and efficient way.

In this thesis we implement one such fast computation algorithm on a 16 bit fixed point TMS320VC5416 DSP starter Kit (DSK). The DSK runs on DSP/BIOS kernel using data pipes for data transfer and software interrupt for scheduling. The work done here can be used as a framework to develop and test algorithms that exploit the benefits of MCLT. We have successfully implemented the framework and achieved perfect reconstruction at output, without missing any real-time deadline or adding any distortion. We discuss and present implementation procedure, instrumentation metrics and test results.
