Unfiltered recordings of pulsars ... where are they?

Unfiltered recordings of pulsars ... where are they?

Almost all pulsar recordings on the web have clearly been thru some filtering. Although this makes for a very pure tonal sound in some cases, or a constant thunking in others ... you don'e hear these objects as the radio telescope hears them.

It would be nice if some entity were to publish fuller length unfiltered pulsar recordings on the web. Hearing these objects are they are would be more interesting.
