You often need to open the audio file in a tool like Audacity . By switching the view from "Waveform" to "Spectrogram," a hidden flag or code may appear visually in the frequencies.

If the ZIP is encrypted, the name "Tune-in-to-the-show" might be a hint for a password or a specific broadcast frequency (e.g., 101.5 ) used as the key.

Check the comments or metadata of the ZIP file using exiftool or zipinfo . Sometimes the "feature" is a hint hidden in the file headers.
