(First post, so bear with me)
Recently, I’ve tried to make my own fire alarm horn sound. I tried a few things but ended up settling on a sine wave swept at 60 Hz with an effective frequency range of 2500 to 5000 Hz.
Since I can’t upload audio files, to see what I mean, you can do this if you have Audacity (it’s a free and open-source audio editing software):
- In Audacity, go to “Tools” > “Nyquist Prompt”
- Copy and paste this below where it says “Enter Nyquist command”:
(hzosc (sum 3750 (mult 1590 (osc-tri 60))))
- Click “Apply”
Love to know your thoughts on it.
