Hey everyone, if anyone is interested, I made this app to create custom binaural beats. You can pretty much change everything about the binaural beat, including the carrier frequency (which is basically the baseline frequency), the specific frequency of the binaural beat, the shape of the waveform, the background noise (white noise, pink noise, brown noise) and finally media overlay, which I am still working on. At the bottom of the app there are pre-settings for all different types of brainwaves. Just make sure to use headphones.

If you have any feedback feel free to post it here.

Thought I should update, I bought a URL to host the evolved app, it ishttps://brain-beats.com/ If anyone has any feedback please don’t hesitate to post it
Nice work! I came across this in another forum which may be of interest.

Tried the newer version, and a couple of notes from a listening/measurement point of view rather than a health one.
The carrier choice matters more than people expect. Below roughly 200 Hz most headphones start rolling off and the two ears no longer get equal level, which smears the beat; somewhere in the 200-400 Hz range the beat tends to be much cleaner and less fatiguing than at 100 Hz. Worth putting a hint next to the carrier slider.
On waveform: a square or saw carrier gives you harmonics that each beat at the same difference frequency, so what you actually hear is a stack of beats plus a lot of high-frequency energy. It sounds “stronger” but it is mostly harshness. Sine is the honest option for the beat itself; if people want texture, better to add it via the noise layer, which you already have.
Two things that would make the app noticeably better: a fade-in/fade-out of a few hundred milliseconds on start and stop so there is no click, and a level match between the two channels (even 1 dB of imbalance pulls the perceived image off-centre and weakens the effect).
One thing to be clear about for readers coming from the PEMF side of this forum: this is audio into headphones, so the low “brainwave” numbers exist only as the difference between two tones, not as an actual sub-20 Hz sound. That is a different delivery route from a coil, and neither one substitutes for the other. A free generator app like this is fine for experimenting with what the beat frequencies feel like before you spend anything.

Thank you very much for the feedback! I will work on incorporating both recommendations into the app.
