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.
Raspberry Pi Pico (RP2040) playground
Music generation on RP2040 with CMSIS-Stream, CMSIS-DSP and Arm-2D
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.

Short-Time Fourier Transform (STFT) framework for Electrosmith Daisy Seed
This is my API for digital signal processing (DSP) with ARM Cortex®-M processor using CMSIS DSP software library.
An example project with STM32F411 (aka. Blackpill) to create an USB AUDIO 1.0 device that recognised by the host as a USB Speaker and outputs received audio stream on I2S. Additionally there's a nice pair of emulated analog VU meters on a small 1BPP display. Drivers included for multiple display tipes.
