Here is a sound that i produced in audacity by generating a tone and making the frequency very low. It sounds rather like a humming of a machine or electrical appliance! good for looping and such. Enjoy !.
Printer machine printing an essay. This background noise could be used for an office scene. The printer was an hp deskjet model, recorded using a mp3 player and processed slightly to remove some background noise using audacity.
The coffee machine at the office where i work makes a lot of noise during the 30 seconds it takes for it to brew one cup of regular coffee. The recording was made with my h2 an early morning in january 2009.
Hypnotic machine sound composed of a repetitive clicking noise backed by a loud, complex hum. Mic is repositioned several times during the recording, changing the relative loudness of the hum and click components.
Noise of a big building-lot. You hear constant noise of the engine of an excavator and "beeps" when it is moving. In the background you hear a kind of drill machine or milling machine from time to time. Recorded with a zoom h1.
The washing machine is on spin mode. I'm afraid there's a bit of wind distortion in the latter part of the sound. This might make a neat sci-fi noise, maybe.
