From the Entr'acte website:The information contained in an audio CD can be considered a waveform describing the movement of your loudspeakers’ cones over time. Using a mathematical process known as a discrete Fourier transform the same information can be dealt with as a collection of sine waves of different frequencies and phases. In this album the phase data is reset, discarding half the information in the music. What does the half removed represent? It is difficult to say exactly, but it is related to time and structural relationships. In most cases you would expect each event in the original audio to be smeared over the duration of the transformed track. However, when the process is applied to music that contains highly repetitive structures, certain aspects audibly survive the transformation process.* Layer of foreground noise due to smearing of all frequencies in track over entire duration* Frequencies become phase-aligned halfway through causing central peak* Central peak surrounded by series of symmetrical peaks and dips fading towards beginning and end* Entirely self-contained* Aspects of melodies and rhythms retained but restructured, with harmonic and rhythmic elements fusing beneath noise.
