A piledriver repeatedly banging in an urban setting. An echo is produced similar to the plastic ticking a warped audio cassette makes in a tape player.
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.
Recording someone typed on a keyboard, inverted sense and put an effect echo, wahwah and fade in. Generate à pink noise with a earning to -30db, and put a fade in and fade out. Normalize all to 0db.
