[RFI] software oscilloscope(?)

[Pete Smith]

Is anyone aware of a freeware or shareware (or demo-able) software program
that uses a sound card to produce an oscilloscope-like display of the audio
signal?  I am particularly interested in being able to produce traces like
those in Marv Loftness's book for identifying line noise sources.
