Blast Of Hate (Binaural Recordings)

On October 12, 2026, a performance was conducted at UPD Studio using a synthesizer system with 32 speakers. The speakers were arranged such that they formed a rectangle measuring 118 cm wide and 141 cm tall. The speaker units were positioned such that they faced inward. The dummy head microphones were positioned at the center of this rectangle to perform a binaural recording. The synthesizer consisted mainly of a computer, universal serial bus (USB) device, line selector, buffer, filter, mixer, USB audio interface, and digital-to-analog converter (DAC). The mixer's digital and analog circuits are placed in separate cases to improve sound quality. The 8 front and 8 rear speakers were connected using two 8-channel mixers. The 8-channel mixer consists of a digital and an analog circuit. The digital circuit outputs three types of control signals, which are then fed into the analog circuit. The 16 speakers (i.e., 8 on the left and 8 on the right) were connected using a 16-channel mixer. The 16-channel mixer consists of one digital circuit and two analog circuits. The digital circuit outputs two of each of the three types of control signals and feeds them into the two analog circuits. Thus, the analog multiplexers of the two analog circuits can be synchronized. For tracks 4 to 6, the waveform audio files were played back from a computer sequencer. The two output signals from the computer were fed into the 16-channel mixer via the USB audio interface and DAC. The USB audio interface feeds the optical digital output into the DAC. This system uses a mixer and speakers to move the sound source back and forth and from side to side, allowing users to enjoy 3D sound. Please listen with headphones to enjoy the full audio quality of this system.
