question on alarm noises, standalone or mp3
I have been looking for some of the more odd alarm sounds i have heard in movies or in documentary, one example is the chiming alarm in the Apollo 11 when it alarmed when on decent to the moon, it started out as a loud almost since wave sound that decayed in amplitude and ii believe shifted in frequency, it had a more plesent sound then say the master buss B under volt from Apollo 13 but that would be a nice one to have as well. I have not been able to find the alarm from Apollo 11 isolated from the speech in the recordings i have found
A standalone schematic i think would be great but a mp3 i could work with as well with just a cheap voice recording kit, but what i don't generally want is a simple siren, already have a few of them laying around.
even a motor driven siren that i can vary the voltage to the motor would give me the decay, i had one made from plastic but the motor failed, i am looking for just about anything except the simple siren kit that i see all over the place unless it can do other tones, heck even Arduino sketch's would be workable. i just don't where to start to look, some sounds would be for a real danger but i need others for non critical stuff that does not need to be 120db
thanks
