Sorry that timers didn't make the cut this round guys, I think I've figured out a good way to implement it, and it's certainly my next milestone in the project!

-----

edenBeats is a realtime, multi-track binaural beat generator.

Available on the android market, QR and link below!
This is my first android application, so please don't hesitate to tell me flat out 'yer doin' it wrong!' or give suggestions on how I can improve the app or app flow.

I thought this would be a neat first-go at android development, something light and fun but a little challenging, and I've learned quite a bit over the last couple of weeks developing it.

Binaural beats are a phenomenon created when two slightly different frequency tones are supplied to each ear. Your brain simulates the interference patterns you would normally hear if the tones mixed in the air ( think tuning a musical instrument, this is a monaural beat ), creating a virtual interference pattern.

Binaural beats are said to stimulate hemisphere-synchronization as the two lobes of your brain work together to mix the sounds, entraining your brain waves to match the interference (beat) pattern frequency. The effects are said to be drug-like, I tend to find a pleasing, low-frequency beat to be a great meditation aid. Try mixing several tracks with different frequencies, or many tracks at the same frequency to accentuate the beat pattern.

Again, this app is meant to be used with stereo headphones.


[Updated 10/06 to v1.3.0]
v1.1.1 - added a white noise generator.
v1.1.2 - accidentally deleted everything.
v1.1.3 - amazingly, recovered everything.
v1.1.4 - added volume controls!
v1.1.5 - added auto pause/resume during calls
v1.2.0 - interface cleanup, added white/pink/brown noise options
v1.3.0 - save & load*! presets! new help docs, several bug fixes and new frequency controls

...
* - saved playlists are stored in /sdcard/com.edencomputing.edenBeats

Nice, I remember messing around with I-doser a couple years ago. I actually liked it. I'll give this one a shot, thanks.

Thanks for checking it out

I haven't implemented any 'white noise' or anythign like that yet, just the binaural beat tracks.

I've been starting it up and then playing some light mood music over the top of it, pretty relaxing.

I'd like to get any major bugs worked out before releasing on the market, so I greatly appreciate anyone who wants to test this out and give some feedback!

edenBeats is ADMOB supported, I may release a 'donate' version to get rid of the ads as well.

I read a story about these "binaural beats" on slashdot not too long ago... maybe a couple months. I am definitely interested in testing it but I don't know that I have a pair of stereo headphones that are compatible for my nexus... . I have a pair of tritons for my xbox 360 slim though! Got any suggestions for headphone use?


edit: scratch the headphones. I ordered some. Definitely going to give this a shot.

Edit2: scratch that scratch. Stocks are stereo. Will play with and report back after work!

Yeah, any stereo headphones should do as long as there's really seperation between the channels. Some cheaper earbuds I've had mostly seperate the channels, but there's some leak between them.

Basically, if you start it up, set a beat frequency and listen to just one channel ( just left, or just right ), you should only hear a single tone with no 'beating'. If you hear the beating in just one ear, your headphones are leaking audio between the channels.

Very good advice. It's funny because I work with stereo seperation every day at work...visually, however .

I am most interested in the theta wave emission during sleep. Do you happen to know the precise values for each track to trigger this?

I have found one thing that is slightly inconvenient.. Setting values. Maybe add scroll left and right arrows for fine tuning?

Heh, not sure there's much in the way of 'precise' when it comes to binaural beats, seems like experience differs from person to person (no surprise), so experimentation will find the right values for you.

If this app takes off at all, I plan to include saving and restoring tracks so you can reload a group of tracks you've liked before.

To pseudo answer your question, Theta waves range from ~4Hz to ~7Hz, I've found that a low frequency base tone ( ~60-100Hz ) is the most relaxing in that beat range if the tone is solo. Once I add in white-noise it won't matter much which base frequency is used.

Programmatically, unfortunately, I plan to add it into the next version. No white noise in this one.
