We have some fluorescent lights that are causing a buzz in our sound
system. I am pretty certain the ballasts are magnetic type. Would changing
them to electronic ballasts reduce or eliminate the buzz?

This guy know everything about lights including fluorescents. If this
doesn't answer your question, he has is email address somewhere there.
You can send him your question.

Yes

The correct answer is "maybe". Be sure any electronic ballasts
indicate they meet FCC Part 15 requirements on noise enmissions,
otherwise, electronic ballasts may be even noisier.

Also ask about using the proper tubes.
I tried regular T8 34 or 40 watt tubes in an electronic ballast
fixture, supposed to take T10s (I think those were the right tube
numbers?) just to test out the fixture after doing some mechanical
repairs to it.
And the ballast seemed to get unduly hot after a short while. For
permanent use of course we use the proper tubes in the proper
fixtures. Just a suggestion.
Some electronic ballasts and other devices do seem to generate undue
amounts of RFI (Radio Frequency Interference). Why the FCC and other
regulatory agencies don't do more to test, ban and remove from the
market more of those items (light dimmers, timers, even some CFLSs
etc.) is unclear!
Lobbyists maybe?
