This sound is 50 ms, 2000 hz pure tone with double linear fadeout through it's whole length. Sampling rate of 8 khz is already an overkill (nyquist frequency is at 4 khz, while all energy of this sound is present in narrow 2 khz frequency range). Created with audacity for use with ardour 3, a free and opensource daw for linux and mac (http://ardour. Org).
