A List of my Academic Papers

  1. The Challenges of Transcription of Music, NYU Tandon School of Engineering (December 2011): Explored signal processing challenges in music transcription, focusing on pitch detection and dynamics estimation from audio sources. Implemented and evaluated the YIN algorithm for fundamental frequency estimation, achieving robust pitch detection for monophonic signals. Proposed preprocessing and post- processing enhancements to improve algorithm accuracy and stability in noisy environments. Results were validated through human subject experiments and comparisons with spectrogram-based methods.

  2. Application of STFT: Time Stretching and Pitch Shifting, NYU Tandon School of Engineering (December 2011): Developed a robust implementation of the Phase Vocoder using the Short-Time Fourier Transform (STFT) to achieve time stretching and pitch shifting of audio signals. Addressed challenges such as phase discontinuity and windowing effects, enhancing audio fidelity during transformation. Proposed novel parameter optimization techniques for balancing impulsive and melodic signal processing. Validated the algorithm’s effectiveness through MATLAB simulations, with potential applications in audio engineering and music production.

  3. Real-Time DTMF Signal Decoder and Encoder, NYU Tandon School of Engineering (December 2011): Developed an efficient real-time Dual Tone Multi-Frequency (DTMF) decoder using Goertzel’s algorithm, optimized for embedded systems. Designed and implemented a noise-gate triggering mechanism to improve decoding efficiency and minimize computational overhead. Validated the system by decoding audio signals with varying noise conditions, demonstrating robust performance. Delivered a comprehensive software package including a DTMF encoder, decoder, and an integrated encoder-decoder pipeline with support for WAV file operations. Potential applications include telecommunication systems and audio signal processing.
