This not a Meme but the spectral view of "Barcode Brothers - Tele" a song from 2008, how many DTMF code tones can you find?

Here have some more

DTMF (with examples): https://www.sigidwiki.com/wiki/Dual_Tone_Multi_Frequency_(DTMF)

Decoder options: https://github.com/EliasOenal/multimon-ng https://www.w1hkj.org/files/fldigi/

Or decode by hand using a Spectral display, in some cases other audio effects can negatively impact the precision of automated detection.

Iirc, if you use a non-linear scale, it comes out properly as his face.
