Overview
Audio Spectrum is a steganography-style forensics lab built around an audio file that may not reveal its hidden content through normal listening.
The useful investigative move is to change how the evidence is viewed. Spectrum analysis can expose frequency patterns, visual shapes, or encoded clues that are not obvious in the waveform or playback experience.
This lab is a good fit for learners who want to practice thinking beyond default file viewers and choosing the right representation for the artifact.
