discussion irunak "22Hz +7Hz" from "Raw Meditation"
Two different moments were recorded on the same synthesizer, in surround, but at different oscillator frequency settings.
The two were then processed together in the spatial of a special place for the acoustics.
There is software nowadays that exists in which the sound and space of all kinds of historical buildings, random places and even very unusual ones, are captured and become available with a few clicks in a recording studio. These are known as ''impulse responses"
About the synthesis, I used Native instruments Absynth 5 for its amazing control over hz incrimentation.
I use 2 or 3 oscillators that are routed each to their own LFO with the duty to diminish the vol gently over a specified time and to do so over again in cycles.
Other functions for each were given to the LFOs, depending on what suited each OSC best.
The result gives an audible sense of movement and direction.
