Segmod is a non-standard sound synthesis that embraces the discrete nature of digital sound. All sounds created with Segmod result from the concatenation of simple periodic waveforms, such as sine, triangle, and square waves. The sixteen contributing composers have employed a vast array of different compositional, aesthetic, and technological strategies, ranging from inaudible sounds, to neural networks, chaotic functions, careful micro-montages, and analysis-resynthesis techniques. While the results differ widely in sound, all lead back to the idea that synthesis can be seen as a form of composition.

In "Chromatisch (8 Oktaven über 1/8 Hz)", a sine wave rises from a frequency of 1/8 Hz chromatically over eight octaves to 32 Hz. Each frequency appears for the duration of one oscillation, so the pitch determines the duration of the sound. In this respect, the title refers equally to the ascending scale in semitones as the course of time.
The digitally generated audio file, created utilizing Segmod, contains frequencies in the very low, mostly inaudible range. The auditory perception depends on the physical characteristics of the playback system used. If you stop the playback of the file before its end, different sounds can be heard, caused by the falling back of the speaker cone to its original position.
