Group kmm-this is a sample of someone walking. There is wind noise. You can hear the footsteps that they are taking. Recorded with a zoom h4 handheld recorder, high gain.
While outputting a file of sound effects, i ended up with a severely corrupted file. Playback results include incessant shrieking and slight pitch alterations. To create more variety, i used a lowpass filter and long reverb.
Grey noise is random white noise filtered in a way to be perceived as being equally loud at all frequencies. Looped version of http://en. Wikipedia. Org/wiki/file:gray_noise. Ogg.
Brown noise heavily filtered and pitched down (not very much happening above 400 hz). Simple chorus/reverb added. Made using adobe audition (previously known as cool edit).
Synthesized sawtooth sound with increasing pitch. An initial click and noise are added. The sound is low-pass filtered using a cutoff frequency that increase during the sound.
