Eero, thanks for your comments. My guess is the lassoo technique can work
with a simple patterned noise such as the audience member whistle in this
but not so sure it would work on swish or hiss which is essentially random,
and which is a far more common problem with legacy, damaged and amateur
recorded media. I suspect if random noise could be surgically removed from
legacy media it would justifiably cause a sensation...
