本文以德國媒介理論的科技數學取徑來探討聲音場域的數位化。根據基德勒提出的字母、類比媒體以及數位電腦三個階段，特別標舉數位電腦階段中數學對於時間軸操弄議題的重要意義。藉由連結拉岡的真實界概念以及傅立葉轉換， 本計畫嘗試揭示電腦如何能依據離散數值進行音樂的模擬和操弄，從而凸顯基德勒後期對於文化數學的關切。 

 This paper addresses the digitalization of the sonic field by employing the technomathematical approach of German media theories. Following Kittlerian three marked stages of the alphabet, of analogue media and of computer, the project places special emphasis on the mathematical dimension of the final stage in terms of Kittler’s articulation of Lacanian Real and Fourier Transform on the issue of Time Axis Manipulation. With the technique of simulating human perception and manipulating sound events, the universal machine computer, which can then create any music in operation of numerical values, highlights later Kittler’s concern with cultural mathematics.
