My vague memories from “signal processing” class remind me that those algorithms usually require lots of numerical calculations. Simply saying - if digital audio is represented as a list of numbers - any conversion of it would require some kind of number crunching which is not the strongest side of the BEAM.
(I wonder if Elixir Nx might change that in the future, though right now it’s more focusing on ML problems.. also there is a library pelemay that could probably help (?))
