A reel-to-reel tapecorder with the record switch on. Time has not been kind to the device, and now a loud sine wave pulses through the speakers when recording with it.
A few notes from a flute were transformed using the hps model with frequency stretching. A sci-fi 'spaceship' sound is produced. The track is 44100 = fs, mono.
Here is a captured sound of a boiler in a neutral state and turning on, near the end of the clip. I personally used this for the background ambience of a spaceship. Enjoy.
A weird beep created using a ehx memory boy modulating the pitch with a square wave at a fast ratio. Recorded with an sm57 in front of a fender blues junior.
