School bell and paging and intercom

#1

Hi I’m using the GSC3510 speakers in a school for paging and intercom and bell schedules
any recommendation on which format the file should be
that I’m broadcasting the sound for the schedule or for the brakes
I’m using some bell sound files from the Internet but I don’t like the way it sounds
any help will be appreciated thanks

It depends on the way you play it.

I’m sending it through sip phone call paging

.wav
16 Bit
8KHz
Mono

Should be a safe option.
