Voice Transformation Through Frequency and Speed Modulation Techniques

1. Implement voice recording with time-frequency domain processing to achieve voice transformation through pitch shifting and time stretching, ensuring processed audio maintains intelligibility. 2. Develop GUI for visualizing input/output signals in both time and frequency domains, with comparative waveform analysis for different parameter settings.

Simulated Digital Down Conversion

A MATLAB-based digital down conversion simulation where frequency conversion and filtering are implemented through custom code rather than built-in MATLAB functions, designed for straightforward portability to DSP or FPGA platforms. Includes practical implementation approaches for signal processing algorithms.
