This is a precise emulation of the audible time signal broadcast by radio station wwv of the nist in the usa on shortwave. This recording was produced via a program i wrote that emulates the time signal and recreates it from scratch, but it conforms precisely to the specs of the real signal. The only part missing is the voice announcement of the time, which, in the real broadcast, is made during the last fifteen seconds of each minute (which is why the tone changes to just clicks during that time). There are two minutes in the recording, but it should be easy to loop it or otherwise modify it for other durations. Since this audio file was computer-generated from scratch, it contains no noise, but the real broadcast has some static and noise, especially at large distances from the transmitter in colorado. Generated by special software / 48. 1 khz 16-bit stereo.

I made this as a near ultrasonic sms signal. Created and edited with audacity, filtered with glame bandpass filter. If you hardly cut a pure tone, you introduce a whole lot of other frequencies to the signal at the cutting point. To avoid this after the cutting you need to filter the whole thing with a bandpass filter to ensure you have as little other frequency content as possible. It will audibly soften the start and the end of the sound. That's what i did here.
