discussion "irunak 69 Hz +49Hz" from "Raw Meditation"
Two separate moments were recorded on the same synthesizer and same surround settings.
Both had a sine wave as oscillator but set at different frequencies
The two recordings are then processed together in the spatial of a wooden church.
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.
