Students create a spectrogram from an audio recording, using MATLAB. They use this to identify the time that a crucial noise was heard, later to be used to determine the time and location of the sound occurring.
A process called 'trilateration' is used to determine the location and relative time the noise was made based on the compiled information from the workshop.

Join us for an exciting data science workshop focused on digital processing and its application in digital forensics. In this interactive session, students will step into the shoes of a digital forensics detective tasked with solving a crime.
Through hands-on activities, students will learn to apply sound processing techniques to isolate and pinpoint the origin of a specific sound, as well as use image processing to identify the culprit.
This half-day workshop utilizes MATLAB software and involves script coding. Students will utilise their prerequisite knowledge of matrices and arrays, PEMDAS/BODMAS, and functions and variables in coding.
This workshop is suitable for students who are comfortable with script coding experience, and who are studying Maths Methods and/or Specialist Maths.
