Spectral analysis of Signals
dCode does not enable to realize spectrum analysis or to hide text by generating noise un a audio file, but here are free softwares to help to perform these tasks. (see below)

Answers to Questions
How to find a text in an audio file?
Sometimes a text (some letters) or an image (rather a silhouette) is hidden in the sound spectrum. A list of free tools to get a spectral analysis or audio spectrum:
Example: Audacity : [] (Menu Analyze then Spectrum).
Example: AVS Audio Editor : [] (Button Spectral in the toolbar).
The tools offer other options such as representation of the signal or sound frequencies.
How to hide a text in an audio file?
dCode suggests these tools (free):
Example: Coagula Light : [] (Draw with the brush in the left window (black) then click Sound> Render Image, then File> Save sound As).
