Feb. 2025 - April 2025
Synopsis¶
Designed, tested and implemented 3 methods for real-time audio detection using the real-time DSP boards,the TI LAUNCHXLF28379D and BOOSTXL-AUDIO. The methods detected:
- The elevator’s floor announcement for floor nine
- A beeping sound from pressing the elevator buttons
The solutions were designed and tested using Matlab/Simulink and then deployed onto a DSP board. The 3 methods implemented were:
- Frequency thresholding for beep detection
- Cross correlation of frequency spectra using STFTs
- Trained linear SVM to perform audio classification using MFCC features
Skills¶
Below are the skills and experiences gained from this project:
- Competencies with Simulink and MATLAB
- Competencies using the Audio Toolbox, Embedded Coder and the Deep Learning Toolbox
- Knowledge of real-time dsp concepts and principles
