When it comes to crafting songs and making music, several artists have gone one step further outside of the musical spectrum, by embedded and hiding actual images and pictures in their songs. So how can you see an image in a song you might ask? You’ll need to download a tool known as a spectrograph (there’s lots of free versions of them online). The spectrograph essential allows you to visualize the waveforms and an audio signal from a piece of music and it’s within these waveforms that artists have been inserting images. The likes of Aphex Twin, Radiohead & Nine Inch Nails have all used this technique, and surprisingly enough, it’s not that complicated to do.
