Introduction

This STM32_AI_AudioPreprocessing_Library is a C Library for audio preprocessing in Artificial Intelligence applications optimized for STM32 devices. It provides the building blocks for spectral analysis and feature extraction, such as:

• Spectrogram computation
• Mel-scaled and LogMel-scaled spectrogram computation
• Mel-frequency cepstral coefficients (MFCCs) computation

Toolchain Support

The library has been developed and tested with IAR version 8.20
