Our Brain and LFOs đŸ€Ż

edited September 2024 in Other

This could explain why the repetitiveness of minimal techno helps me concentrate.

I am pointing out the low frequency repetitiveness, not necessarily an actual LFO per se.

I know binaural beats can modulate brain waves.

Anyone else experience this from listening to minimal techno?

  • Heck, maybe this is a mechanism in enjoying music in general.

    That could be part of the answer indeed. I haven't listened to much minimal techno but everytime I did, it always captured my attention...seamless variation through endless repetition. It kind of echoes all those cycles in our own lives in a way.
    I have the same feeling when listening to some repetitive music from Steve Reich, in particular music for 18 Musicians, which works wonder on me when I am excessively tired during period of sleep deprivation. As if the pulse was aspiring my mind to a different state and helps me look forward. Or as if the repetitiveness helps resetting my internal clock.
    Not sure it makes sense for others but surely makes sense to me 😉

  • I really doubt sound frequencies are directly correlated to brain waves. It's rather your emotional state, when listening to music you like or dislike, that produces brain waves.
    Some people like minimal techno or steve reich, others don't, and I'd bet money that you'd read things completely different amongst a group of people wearing a EEG.

  • The lowest frequency in a techno rhythm you'll ever find is about 2 Hz (i.e. 120 BPM), so I doubt it has anything to do with these particular oscillators in the brain.

    Makes great sense to me 👍 thank you for sharing.

    Eww. I just noticed your screen grab is AI
    I’ve sometimes wondered if binaural beat music is a gimmick. I know binaural is real, but I speak of the alleged or marketed affect
    of the summed/differential between the two frequencies.
    I’ve tried listening in the past but find the content to be grating and anything but soothing or focus inducing.
    However, when I had tried, the streaming platforms were probably already saturated with content from fly-by-night binaural producers hoping to make passive income.
    Any listening suggestions and or science would be welcome.
    As someone already suggested, I’m guessing it’s your emotional state responding to your likes and dislikes, psychoacoustic.
    For me, +1 for certain flavors of techno.
    Also, atmospheric D&B gets me there.

    I'm a natural skeptic but do (tentatively) think binaural beats work based on experience. I say "tentatively" because I just can't fully suppress my skeptical side.

    From what I've read, the beats don't have to be embedded in music, and you should be able to listen to music or other content over them without reducing their effectiveness. For convenience, I have the Brainwave app, which lets you freely mix the beat producing tones with any other sound source, such as from other apps, or with sound effects, or different colors of noise. I usually mix the beat producing tone just loud enough so I know it's there, but not so that it distracts from listening to the other sources.

    I've also explored isochronic tones which some say act the same, or even better. The difference is that volume fluctuation rather than offset frequencies are used. If valid, that would presumably make them effective even without headphones.

    I've also set up miRack and Drambo oscillator combinations that make binaural beats from different frequencies based on the Hz that I select. I've also used LFO's to produce isochronic tones in Drambo.

    It seems to me that "LFO" could be abstracted to overall dynamics or repetitiveness. If there was a dynamics shift over a number of measures I would think it reasonable to wonder if the brain might not see that as an LFO cycle. Just total speculation though. Fun to think about but difficult to fully accept for me at least.

  • I think that it's not really something about the use of lfos but just something about the ability of subtly varying repetition to induce trance like states. Repetition with small amounts of variation is more engaging than repetition with no variation. There is still enough novelty to keep you interested, but not too much novelty to risk breaking the trance state.

  • So I’m not crazy, it was them LFO’s all along

  • But what if I patch those LFOs into my resonance? Will I have a peak experience?

    Which makes me wonder if harmonics could come into play as well. Also, echo/delay, eg in dub, which (for me) certainly changes my mental state (without intoxicants).

    Bottom line is we (humans) are awash with cycles and vibrations, so I guess it’s unsurprising that an art form reliant on the same resonates (possibly literally) with us. Might also play into why some music works for one person and not for another, as we’re all different.

    Here's the isochronic version: It's just a Sine wave with a square wave to modulate the volume. I send the LFO through a filter to tame the harshness of the volume change. The other layers are to add in pink noise with HP and LP filters to adjust its range if wanted. The Ambiance layer is currently Radio Unit playing Soma FM Drone Zone or whatever I'm in the mood for.

    Here's with the hidden modules exposed.

    Sorry @tyslothrop1 - I'm not sure what I did with the binaural beats version. I remember it just had two oscillators panned left and right with a math module between them to add the value from a calibrated knob to the frequency of the 2nd oscillator. I may recreate it later today if I can't find the original.

    They work, that’s scientific fact. It’s probably (just my hypothesis) because sound is is most heavily processed sense - during listening there is more activity in brain than for any other sense (including sight).

    Brw just partially related - i am trying the “Gateway experience” stuff - as absolute skeptic, just out of scientific curiosity - started just to be able to say “i tried it and it’s bullshit’ - i am just at the beginning but it starts to be really strange 


    Prerty curious what it will be when i advance a bit (google it if you don’t know, it’s old CIA experiment based on binaural beats, there are recordings on YT available).

    I didn’t believed nothing about it and i still highly in doubt but as i said - things slowly starting to be weird.

    Thanks wim. I've tried myself with an oscillator split into left and right with a frequency shifter on one side to get the difference and then back to stereo. Your solution with the math module sounds more efficient. Please share, if you find it!

    I tried the gateway stuff, too, although I'm too lazy to do it on a regular basis. I guess you're talking about Robert Monroe's gateway experience. I don't know of any relations to the CIA, haven't researched it, so I can't rule it out, but I thought of him more like a hippie scientist into consciousness change. And it's not just the binaural beats, but also the mental exercises that are also on the tapes, that make it interesting. I've tried quite a couple of relaxation tapes with and without binaural beats and this is the one that went deepest. I should find it again and do it regularly.

    funny thing is first time i tried nothing happened so i gave up after probably 10 tapes.. recently decided to give it a shot again and.. weird feelings starting to appear.. this time will continue for longer to see if it’s just random or i am really onto something this time

    I think it is possible to tune aspects of your brain function to a specific frequency. I do it almost every day, singing with a drone.

    120BPM at 2hz would have a subharmonic series in slower LFO range that could potentially sync to the BPM tonic. Might be fun to experiment with!

    Speaking of resonating to drones. Some time ago, I bought this, unfortunately no longer available app on steam:

    https://store.steampowered.com/app/590510/SoundSelf_A_Technodelic/

    I use it with my phone and a relatively cheap vr-headset and It's pretty cool.

    The developer must have changed his business model and offers hardware and software packages to therapeutic practices and doesn't seem to sell the software to consumers anymore.
