This sound is a reproduction of a steps throught a large corridor in tallers. It is a repetitive sound with different pitch in each step, it seems sinusoidal sound.
A short melody created in bosca ceoil and then pitch shifted and notch filtered in audacity. No rights reserved and no attribution needed. Boost no ills.
Are there a million of these sounds in film trailers? are there a million of these sounds on freesound? not sure. Started with 100k tone - pitched it down over time - it was too low, so then i pitched the whole file up a bit. Insert to make any slow mo sweeping matrix style scene look even more awesome. . . Or not.
Recreating the pitch shift used by pink floyd in echos. Inspired by taking the now retro echophonto its extreme flange edge and tweaking. . . Rendered in reaper with markers at 48 khz 32 bit fp for the beloved morphagene fans out there. Go back in time and enjoy!.
This is the variable mid/high pitch sound of a metal door not properly closed in my college, making a whistling sound. There are very light sounds of people passing and chatting by the door. I used this sound in a group project as part of a night wind sound in a dark forest. It is looping. Recorded with a tascam dr-40.
