Removing Narration

[GeorgeCB]

The quality doesn't need to excellent, just good enough to stand on its own

I suspect that won't be possible from the sample that you posted. Parts of the whistling are totally obscured by the narration, such as the first part of the clip.

The obvious solution is to find one or more people that can whistle, and record them. To create the effect of lots of people whistling, you can "overdub" (see: http://manual.audacityteam.org/man/tuto ... rdubs.html)

Thanks Steve - I feared I may be on to a loser with this one but I'm grateful for the help offered.

a reasonable amount of isolation is possible.

How?

Whistling is mostly narrow band noise, and so can be removed quite effectively using the Spectral Edit Multi-tool to notch filter out the whistling.
Before doing that, make a duplicate copy of the track and invert it.
After filtering out the whistling from the original track, mix it with the inverted copy (Tracks > Mix and Render). That will "cancel out" the parts that are "not whistling".

Thanks Steve and Koz for your help with my project.

I've decided to use an original recording of Keep The Home Fires Burning. This isn't in the move but, what the hell, no-one's going to hear it but me.
