Acoustic features (MFSCs and MFCCs) for edge AI
GNU Octave scripts to design IIR filters that can be HW accelerated on ARM Cortex cores via CMSIS DSP
IIR filters coefficient generation for ARM CMSIS DSP library using GNU Octave Script.
Music generation on RP2040 with CMSIS-Stream, CMSIS-DSP and Arm-2D
Raspberry Pi Pico (RP2040) playground
This project aims to implement a speech command recognition system on an STM32F407 Discovery board. The system is designed to predict two keywords, "yes" and "no," while classifying other sounds as "noise." It utilizes embedded audio processing and deep learning techniques to achieve efficient speech recognition on a microcontroller platform.

Master's Thesis: "Acoustic Identification of Wood-Boring Insects with TinyML".
This is my API for digital signal processing (DSP) with ARM Cortex®-M processor using CMSIS DSP software library.
Short-Time Fourier Transform (STFT) framework for Electrosmith Daisy Seed
A real-time audio spectrum analyzer I developed using the STM32F4 and ARM CMSIS-DSP library. I processed analog signals using the FFT algorithm, visualized them on an OLED screen, and enabled data recording to an SD card.
