🎧 A simple note about spectrum analysers & “4.5 Hz/7.83 Hz/528 Hz” 📊

Every now and then I see comments like:
> “I measured this and it isn’t 4.5 Hz, it’s around 100 Hz.”
> “I checked this ‘528 Hz’ track and I don’t see a big 528 spike.”

Totally fair questions.. here’s what’s actually happening.

🧠 How binaural beats work

A binaural beat has two things going on:

- The carrier – the actual tone you hear in your ear (for example ~100 Hz)
- The beat frequency – the difference between left and right (for example 4.5 Hz or 0.5 Hz)

Example:

- Left ear: 100 Hz
- Right ear: 104.5 Hz
- Your brain: “There’s a 4.5 Hz difference between these two.”

That 4.5 Hz is not a big separate note you can point to.. It’s a slow wobble created by the gap between the two audible tones.

Same with 0.5 Hz: it’s the difference between two close carriers (for example 100/100.5 Hz), not a low rumbling note on its own.

🔊 Why you don’t “hear” 4.5 Hz as a pitch

Human hearing only picks up pitches from roughly 20 Hz and up.

So:

- You don’t hear 4.5 Hz or 0.5 Hz as a normal “note”
- You experience them as slow pulsing / drifting in the sound
- A spectrum analyser will mainly show you the carriers (80–200 Hz-ish) and the noise/bass, not a giant spike at 4.5 Hz or 0.5 Hz

When someone measures a track and says:
> “This looks like ~100 Hz, not 4.5 Hz,”
that’s actually correct.. They’re looking at the carrier tone. The brainwave number (4.5, 7.83, 0.5, etc.) is the gap between left and right channels, not the main pitch you’re hearing.

Most of my binaural carriers live roughly in the 80–200 Hz range, and the entrainment comes from the difference between them.

🎯 Example: “DNA Repair Grid | 528 Hz & Delta Healing Blueprint”

Another common one is:
> “I analysed this and I don’t see 528 Hz.”

In that track:

- The deep delta work is done by a 0.5 Hz binaural beat around ~100 Hz (for example 100/100.5 Hz).
- The 528 Hz “miracle” tone is used as a harmonic layer in the grid. It’s part of the architecture, not the main loud carrier.

On an analyser you’ll usually see:

- Big energy in the low carriers (around 80–200 Hz)
- Bass and pink-noise bands
- The 528 Hz layer will often look smaller or be masked unless you zoom in with higher resolution.

So if your app shows “strong ~100 Hz, smaller 528 Hz,” that doesn’t mean 528 “isn’t there” – it just isn’t the dominant thing in the mix. The track is built as a full field, not a single blaring 528 test tone.

📊 About spectrum analysers in general

Analysers mostly show:

- Whatever is loudest (bass, noise, carriers)
- Smaller harmonic layers and subtle tones can look tiny or “invisible” if:
- the FFT size is low
- you’re zoomed out on the whole spectrum
- there’s a lot of pink noise and bass on top

All of my frequencies are set numerically in the DAW. I’m not guessing or eyeballing them. I actually want people to be curious and check what they’re listening to, but it helps to know what you’re looking at.

It’s always a bit of a shame when someone assumes I’m trying to deceive them, because that’s just not the case. There’s a lot of care, maths and intention behind these builds. If you ever want the exact frequency stack for a specific track, drop a comment on that video and I’ll happily break it down. 💜
