Signal Processing

  • Transforms: Fast Fourier Transform (FFT), Wavelets, DCT, etc.
  • Filters: Finite Impulse Response (FIR), Infinite Impulse Response (IIR), Convolution, Deconvolution, Adaptive Filter (LMS/NLMS), Equalizer, etc.
  • Special Audio Processing: Dynamic range compression, Limiter, Noise gate, Automatic gain control (AGC), etc.
  • Audio Codecs (Opus, AAC, SBC, FLAC, Shorten)



Research Papers

Open Source Projects

  • ardour: Ardour is a Free Digital Audio Workstation (DAW), maintained by a diverse community of developers. Collaborated to optimize Ardour’s mix engine for Intel/AMD CPU with AVX extension. Also, optimized for ARMv8 and ARMv7 CPU with NEON extension.

  • bina-fft: A simple to use Fourier Transform Library, made for education purpose. I wanted to implement and optimize radix-2 Fast Fourier Transform, so I did that.

  • cmuse: Another pointless program (App) that plays "Twinkle Twinkle Little Star."

  • Linux Kernel: Contributed documentation changes in the Linux kernel commit:68f04b571

  • lolcat Collaborated to rewrite the infamous lolcat, a program written in Ruby, to Rust (with fearless concurrency). Added features to emulate dial‐up text scroll and placing rainbow colors in background.

  • Xv6 Kernel: Minor changes github pull request

Environemnt Experience
