From my trusty ninth-floor London highrise balcony, I bring to you some beautiful booms, zipping cars and whaling sirens. Once again using the #Olympus #LS-100 digital recorder and very handy #Jecklin disk with #Cad #M179 condenser #microphones, I urge you to put on your favourite set of headphones, or turn it up loud on your speakers and enjoy the great sound.
