I simply generated a risset drum in audacity with all the default settings, except the frequency is 50. A really powerful sound, but only if you have a good sub woofer.
This is a deep bass rumble sound. Created in audacity by generating a brownian noise and band passing it through a steep 15 to 100 hz filter. The reason for the roll off below 15hz is to remove energy that doesn't produce any sound. It just moves the speaker cone and wastes amplifier power, thus it was rolled off.
Could be interpreted as some sort of liquid noise, creature vocal sound, or many other things. Made using my brother and his infinitely odd noises, and a single effect.
Made this by putting my keyboard through my guitar pedal, distorting the kick drum, then putting an echo on it. I made it to put in my horror film in media studies.
Merged some sounds in audacity. Sitting with crappy headphones. Sorry. Made a deep techno loop with the following sounds. Klankbeeld - city night hum 01 160927_0989. Wavhttps://www. Freesound.
