Public rail passenger transportation systems Studies on 5th generation mobile communications (5G) It’s a great all around library when it comes to designing various electronic machinery sound effects.Search the scientific literature database Inside you’ll find a lot of different hum noises, hiss and electrical swipes and whooshes, buzzing high pitch and low pitch sounds, beeps and bleeps, servo and small engines running in a different way, data processing kind of sounds, interference and corruption effects and more. Everything was recorded in stereo, and in some cases sounds are wildly flying across not only whole frequency spectrum but also pan image. Post production process was limited to EQ and compression with some noise reduction in few cases, but most of the files are ready for further processing and designing completely new sounds. The total length of the files is 6 hours and 18 minutes. Electromagnetic Field sound library features 216 stereo 96kHz recordings of more than 80 different electronic devices.
