through spectral analysis, I have noticed that regardless of which machine is used, whether analogue/digital or which variables are selected, frequencies below 30 Hz always resonate throughout the entire length of the actual sound.
Here is an example of an analogue kick drum (BD Hard), with -0.3 peak level and without any processing, FX, which is running into the DAW via Overbridge (USB).
I would like to understand how and why low sub or infrasonic frequencies are generated here and how they can be treated ideally.
I can imagine that conventional suggestions such as generous high-passing via EQ will follow. I would be interested to know if there are other techniques that are suitable here for treating the signal as precisely and correctly as possible without causing artefacts, phase problems, etc.
Regular speakers can’t move enough air to reproduce subsonic frequencies properly so you’re not risking your health. Leaving them in could be a drag on the speaker cone similar to a DC offset making it lose power and definition so high pass filters are the way.
Synths are usually limited to produce audible frequencies but you could probably use it as an LFO since it can reach slow speeds, much like many modular oscillators.
As to how? It synthesizes cheese energy with cool energy to extract vibes from the quantum void.
Edit: Someone flagged this and I can’t see why. Should I have used a smiley to indicate a tone change to humor?
