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¶
