Sound of sticking a 6. 5 mm jack into a speaker. Cc0, so no need to give credit. If you want, let me know what you used the sounds for as i really like hearing about other people's projects :).
Playing random tunes but reversed them to make it sound like nice suspense, sounds processed with synthesia and virtaulmidisynth, recorded in audacity.
All my sound effects are always created from scratch. Handcrafted using only the finest frequencies and waves. If you alter my sounds in any way i can not be held responsible for your health and safety.
Track was created using audacity®. The track was a generated chirp of 1 sec. Repeated once and then reversed. The gverb filter was used with a low early reflection and high room size value. And then the echo filter with 0. 2 delay time of seconds and decay factor of 0. 5 seconds was applied.
