I almost tripped into posing this question in the music-making subforum, but then slapped my forehead: “Friggin’ ars’ists like myself, likely as clueless!” and swerved toward the audio whizzes.
So, your mage-sty, please confirm that civilization has advanced enough as to grant us a plugin or swift method (if necessary, sidetracking Audacity, as long as the alternative doesn’t cost an arm) which enables impressing the sonic ‘character’ of a sample (say, trumpet) over a recording (say, a sung line).
Audacity has a built-in vocoder effect.

If you’re a musician you’ve probably heard of [u]MIDI[/u]. MIDI is “sheet music for computers” so you can easily switch between a virtual piano and a virtual trumpet and virtual violin, etc.
You can create whole virtual band or orchestra. Most background music you hear in movies & TV is now done with MIDI. Most current popular music has at-least some MIDI and some of it is all-MIDI (except for the vocals). Depending on the chosen virtual instruments it can sound like a real instrument or it can sound artificial/synthesized.
You have to start with MIDI (or start from scratch). Audio-to-MIDI is not “perfected”. And you can’t make MIDI vocals/lyrics, except there are “vocalizations” so you can do "ooh’s & “aaah’s”. It also has a reputation of not being very good at virtual guitar, but depending the style and if it’s part of an ensemble, I’m sure it can be good enough to “fool” most people.
(Audacity is not a MIDI application.)
