In today's popular culture, there is an abundance of imagery related to cassette tapes. T-shirts, smartphone covers, coin purses, bags, and many other items reference the shape or image of the compact audio cassette. There even exists an MP3 player in the shape of an cassette, and certain smartphone applications allow one to virtually load and play a cassette on a tape deck, or even hear your music through an app that lays tape sound over your digital file.

However, none of these items allow the consumer to achieve actual artifice, but only a fake artifice. What good is analog tape sound emulation without actual cassette tape? Cassette Tape Sound Filter allows one to leave behind the false shell of digital-based analog emulation for the real artifice of an actual analog sound filter, without the bother of actually using the media in question.
