"ΔMi−1=−∝Σn=1NDi[n][Σj∈ℂ{i}Fji[n−1]+[Fexti[n−1]]" (often refered to as "Formula", "Equation", "Complex Mathematical Equation" or "Symbol") is a song by electronic music artist Richard D. James, released under the Aphex Twin name on Warp. It appears as a B-side to his 1999 single "Windowlicker". The actual title as it appears on the sleeve is:
![\Delta M_i^{-1} = -a \sum_{n=1}^N D_i \left[ n \right] \left[ \sum_{j \in \mathbb{C} \{i \}} F_{ji} \left[ n-1 \right] + F\operatorname{ext}_i \left[ n^{-1} \right] \right]](../../../math/b/0/7/b075d82953d2feeb9fb6616f53a2dfe9.png)
The track features sounds that wreak havoc on the eardrums of the listener, and has a very experimental sound.
Viewing a spectrogram of the second track reveals hidden images that were apparently synthesized as sound by Aphex Twin for the express purpose of being discovered in this manner. It is one of the few instances of an artist using steganography to embed a representation of his own face into his music (see also these artists: Interlace - Innuendo, Venetian Snares - Songs about my cats).
The effect was achieved through use of the Mac based program MetaSynth. [1] One of the facets of the program allows the user to insert a digital image as the spectrogram. MetaSynth will then convert the spectrogram to digital sound, and "play" the picture. According to an article on the website Wired News, photographs run through the program tend to produce a "dischordant, metallic screeching."
Similar programs to generate sound from images include Coagula (for PC) and the BeepMap plugin for Fruity Loops.
Samples of "ΔMi−1=−∝Σn=1NDi[n][Σj∈ℂ{i}Fji[n−1]+[Fexti[n−1]]" can be heard on the song "54 Cymru beats" from James' 2001 album drukqs.
