Whelen WPS-4003/4004 & WPS-2900 single tone synth

Whelen WPS-4004 & WPS-2900 dual-tone synth

For the single tone synth, I used the no bias square wave with a 320 Hz to 460 Hz sweep and 300 Hz high-bypass with 2000 Hz low-bypass.

For the dual-tone synth, I used the same no bias square wave but with 460/575 Hz dual tone. Low tone sweeps from 320 Hz to 460 while high tone sweeps from 400 Hz to 575 Hz. The attack tone and wail tone use different peak pitches, attack peaking at 475/593.75 Hz and wail peaking at 640/800 Hz.

Both of these synths were generated in Audacity, with the exception of the air horn tone and voice, which were taken directly from https://www.whelenmassnotification.com.
