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.

experimenting with this as a 'keep alert' alarm that's not too annoying
