In the fields of signal processing and engineering, "SPM" and "Radio" intersect in specialized ways:

: Used extensively in neuroscience for analyzing brain imaging data, such as M/EEG (magnetoencephalography and electroencephalography) signals.

: On services like LiveOne and Spotify , "SPM Radio" functions as a custom station playing tracks by the Houston rapper S.P.M. and similar Latin hip-hop artists.
