Here have some more

DTMF (with examples): sigidwiki.com/…/Dual_Tone_Multi_Frequency_(DTMF)

Decoder options: github.com/EliasOenal/multimon-ng 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.

Here’s a fun one:

Aphex Twin / ΔMi−1 = −∂Σn=1NDi[n][Σj∈C{i}Fji[n − 1] + Fexti[[n−1]]

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