[Android Apps and Games] cicada:
In short, base frequency is the tone you hear, and beat frequency is how much that frequency is offset in each ear.

For example, a base freq of 261.63Hz is 'middle C'.

At beat frequency 0hz, 261.63Hz is played in each ear.

At a beat frequency of 10Hz, the base frequency is offset +/- 5Hz in each direction, so left ear gets 259.63Hz, right ear gets 266.63Hz, and the result you hear is a 10 Hz 'beating' as your brain tries to reproduce the interference pattern.

The beats setup a frequency in the same range as brain-wave frequencies - the goal is to 'entrain' your brain waves to a desired major frequency by listening to the binaural beat track. It is believed your brain waves are malleable, and trend toward matching a dominant external frequency, in the case the beat frequency.

If you're hearing a beat in just one ear, your headphones are not separating the stereo signal properly. Each binaural beat track should be producing a unique tone in each ear, and the offset of those two tones is what produces the beat effect.

Try setting up a track with whatever base frequency you want and can hear clearly. Set the beat frequency to 20Hz or more. If you listen in just one ear, you should not hear any beat, and the tone coming from the left speaker will be noticeably lower in pitch than the right.

Listen in both ears and you'll hear the beat frequency you set as a fast pulse in the tone. The really neat part being, the beat only exists in your head.

Heh, I do what I can. I won't get into the details of why you shouldn't try to use SVN when you've just gotten home from a party ;)

BTW, new version coming out in the next few days. Lots of improvements like saving/restoring playlists, bugfixes and other code cleanup.
[Android Apps and Games] djemm1996:
When you are going to release next version? I want with timer. It would be cool. :)
[Android Apps and Games] cicada:
new version released!

Unfortunately timers / alarms didn't make it into this version, but it's next on the chopping block.

What did make it in is the ability to save and restore playlists, as well as a few different Presets you can try out. Don't expect magic or anything, I basically just threw them together ;)

Also added +/- buttons to the frequency sliders to give you more precise control.

I wish I could work on this stuff full time to get you new versions quicker!
[Android Apps and Games] IOInterrupt:
Ok, I think the problem I was making, was that I was setting up two different tracks, and so I was getting a beat affect even with a single pod in. With just one track, they are both solid tones, and one does seem higher toned than the other, but the beat isn't noticeable at all to me unless it's down to around 4hz on the beat freq (must be me!).

So what is the advantage of playing two of the same beat frequency at two different base frequencies? I am real curious!
[Android Apps and Games] evolutioner:
does it not work on 1.6?

cant install on my x10 mini pro
[Android Apps and Games] cicada:
Sorry, 2.1+ only for now.

I initially had some issues with the audio classes I was using and android 1.5 as a target, though that code has changed significantly since. I'll see about those areas and try to make it 1.5-6 compatible for the next version.
[Android Apps and Games] chinds2:
cicada, just wanted to say thank you for your work. I used to use an iPhone app called attractor and I've been dying for an app like this on android.
[Android Apps and Games] Jolest:
Really? I had no idea that was possible. What kind of dyes do you use to get an app created? :)
[Android Apps and Games] frost_icewind:
This app is AMAZING!!!!
[Android Apps and Games] cicada:
Not sure if that's spam or what but the apk is attached to the OP.
[Android Apps and Games] maydaysos:
you read my mind in creating this. But that thats how things work i guess 8)

Awesome Job by the way.
[Android Apps and Games] javacody:
How about an updated version that reads sbagen scripts?
[Android Apps and Games] pingpongme:
I really like this app, hope the timer function will be added soon.

I would also love if it could bring me down from xxHz to xxHz in xxMinutes !
[Android Apps and Games] yagan60:
hope this is the right place to provide feedback to cicada. I really like your app but don't like having to re-enter settings each time I use it. Two mods would make it perfect for me.

1. Enable a 'set' of up to 15 frequencies to be saved to a filename, giving the ability to be reused quickly and often. A library of combinations could be built.

2. Enable frequencies to be selected by a number pad instead of touch slider. the touch slider is cumbersome and time consuming on a small screen.

These improvements would make this app very useful for 'rife' users at home.

Kind regards, Ian (yagan60) Australia.
[Android Apps and Games] Jelly419:
I'll give it a try. I hate my job and have plenty of down-time, so, maybe I can "escape", if only for a few moments. Thanks for your work. I'll report back.

edenbeats audio drops

Hi!

Really nice app!

Noticed this thread is getting old...Is it still being developed?

Would love to use it, but whenever I play any beat the audio drops after 3-5 seconds, first on the left channel then on the right, it might pop back on one channel at a time a couple of times before all audio completely disappears.

Tried both from market and this thread with no success.

If this gets fixed I'd gladly pay for it.

I'm using a Samsung Galaxy S3 with Jelly Bean 4.1.1, all stock.

Thanks for any help and keep up the good work!
[Android Apps and Games] vleutmans:
same issue here

Yes the application is not compatible with both ICS and JB, so needs to be updated.

On ICS i have similar audio drop on binaural tones :(

On GB 2.3.4 the app works great, but i think GB is not available for galaxy S3 :)

A remedy might be to use mp3 instead :

Freeware you find a lot with google, just google on for example "free mp3 binaural download" and enjoy !!!

I hope i helped you in a way.

[Galaxy S I9000 General] uberberben:
Hi,

i have Galaxy S with I9000XWJM5 and have some strange problem when listening to music in my car. I connect phone with AUX cable to my car radio.

The problem is that playback have glitches every few seconds, it's 4-6 glitches per minute of playback. I don't know how to exactly explain that glitch. It looks like you quickly disconnect/connect jack to phone. I've had iPhone, Samsung Wave and several other mp3 players connected that way in my car and none of them had these kind of problems. I've also checked jack and cable and everything is fine. Connection to phone is also fine during testing. Do you think it's because software? Or maybe it's bad checking for AUX signal in the phone?
[Galaxy S I9000 General] andrewluecke:
I'd say most likely software, but I'd be guessing.. There isn't really any way of knowing.. Is this with FLAC?
[Galaxy S I9000 General] uberberben:
I'll try change something in my car audio. I think it might be caused by changes of inpedancy.
[Galaxy S I9000 General] K_19:
I don't get glitches in my car AUX unless the files themselves glitch and stutter (which they do with FLAC files). I would check to see if you have any EQ settings in your car stereo on, that is the culprit sometimes.

How is your playback with headphones/earphones? If you don't have same problems with them then it's likely something with the mini cable or the car stereo. If not, then likely something with the phone hardware/software.
[Galaxy S I9000 General] uberberben:
Playback with headphones is 100% good (sometimes excluding FLAC playback as you said). I'll try changing EQ in car and if this don't help i'll try changing inpedance and write here what happened.
[Galaxy S I9000 General] AllGamer:
have you considered using bluetooth in car to stream audio from the phone instead of AUX cable?

like this

http://xdaforums.com/showthread.php?t=726403&highlight=bluetooth
[Galaxy S I9000 General] uberberben:
I was thinking about it but my car radio don't have bluetooth and I won't change it because it's pretty high end Blaupunkt and I love how it sounds.

Second thing is that a2dp has lower quality that regular aux.
[Galaxy S I9000 General] K_19:
I would also make sure it's not the data/phone connection somehow getting in the way of music playback. Try it on the airplane mode and see if you are getting the same glitches.
[Galaxy S I9000 General] AllGamer:
i think i know what you mean.

you are refering to those annoying sounds when a call is about to coming, or when a data transfer is in progress, or whenever your phone switches from one tower to another tower

you get the ddddddd...d.d.d.d.dd..ddd.d.d.d.d.d.d.dddd... sound on the speakers, if your phone is connected to the stereo via 3.5

that's one of the reason why i switched to BT in the car.
[Galaxy S I9000 General] uberberben:
I've checked line out with amplifier in my house and it's working 100% fine. So i have to check AUX in my car.
[Desire Q&A, Help & Troubleshooting] dr_pepper:
I have alot of respect for Communities such as this, but gotta say the information for the Desire seems to be all over the map. I'm have a little trouble navigating to find info I need.

I have just recieved a new Telus Desire. Pretty sure it is the SLCD version as I see no mention of AMOLED on the packaging.

Firmware version 2.1 update1

Baseband 32.41.00.32u_4.08.00.09

Kernel 2.6.29-e5576724

build 1.29.661.1

Would like to root and get Froyo installed. Seems to be lots of discussion on what works and what doesn't depending on if you have a UK version, an AMOLED version etc. I have no problems reading, but if someone can point me to the information that applies to my specific phone would probably leave me with alot less questions than if I start building my knowledge for rooting around an AMOLED UK version of the Desire that's not even going to work with my handset...........so help?
[Desire Q&A, Help & Troubleshooting] kewvention:
hey ive got the telus htc desire and have it rooted to leedroid rom. the guide i used is in the desire android development subsection. the guide is called: [TUT] Telus Desire HBoot 0.83 Root and Flash

[Captivate General] derek4484:
I have a question about updating market apps.

I have maybe 50 or so apps installed. Some days I have like 8 or 9 updates available. Why do I have to download and install one update at a time. Takes like 20 minutes to do all of them. Why isnt there a feature to "update all" like my iphone had. It seems trivial, but it's a major help after having to update 10 apps at a time every 2-3 days.

Thing is with iphone, their apps are done so much better, there's rarely even updates for them, the update all function is barely needed. With android there's updates almost every day with some apps.
[Captivate General] masterofthebass:
Few things.

1. Froyo is getting the update all button. Its definitely needed, although it takes about 10s to start all the installs for 5 apps, I have no idea how it takes you 20 minutes.

2. As an iPhone developer, the reason why there aren't updates that quickly, is because apple sits there and reviews every single update. Even if you were to submit one, it takes over a week for it to get pushed into the app store. The android market has basically instant updates for developers, so they can send little fixes much quicker.

[Galaxy S I9000 Android Development] BenF1:
Seems to have gone unnoticed here!

To run Ubuntu on Android/Samsung you need to create an img file using my post, you can also use two of my start and stop scripts from here start stop.

Step 1:

Lets begin by preparing our device by create an folder on android, connect your phone to your computer and do:

1
sudo adb shell
2
cd /sdcard
3
mkdir ubuntu
4
exit

Step 2:

Now you can upload the img file and if you like you can also upload my start and stop scripts.

1
sudo adb push ubuntu.img /sdcard/ubuntu
2
sudo adb push startA_ubuntu.sh /sdcard/ubuntu
3
sudo adb push stopA_ubuntu.sh /sdcard/ubuntu

Step 3:

Now that you have done all the prep work you can use your ubuntu by doing:

1
su
2
cd /sdcard/ubuntu
3
sh startA_ubuntu.sh ubuntu.img
Step 4:

To exit just run:

1
exit
2
sh stopA_ubuntu.sh

That’s it, no more no less

[Galaxy S I9000 Android Development] aditya_t90:
Could you please post your ubuntu img file to a file sharing site.

I am never able to create the image. It always fails when i try to build the image.

If you want, I can host it on my server for no cost if you dont have space on your server.
[Galaxy S I9000 Android Development] BenF1:
I found http://www.megaupload.com/?d=FALJFT3L

[Galaxy S I9000 Android Development] AllGamer:
this sounds very fun and interesting.

but, what will we gain by running a full fledge linux in the phone?
[Galaxy S I9000 Android Development] aditya_t90:
I don't believe that those img's are the same.

SGS ubuntu img should be 1G

The Nexus One ubuntu img is 600mb

really nice ! :)
[Galaxy S I9000 Android Development] ArminC:
I have added one of my img files to the blog, Because i am new I can not post urls, please visit my blog you can find a download link there to my img file.
[Galaxy S I9000 Android Development] carlocb:
Oh my god! Is that true?!? You can run ubuntu on the galaxy s?!? O_o

And...how does it perform? Lol...does someone have a screenshot or better a video of this one? :P
[Galaxy S I9000 Android Development] ArminC:
Uhm performance isn't that of your android haha, You can do stuff but it's not that fast.
[Galaxy S I9000 Android Development] carlocb:
LOL, I thought so! But maybe with a lightweight wm like xfce or openbox...

Maybe just opening X with no wm but FireFox open... for *true* flash support (like full Facebook and games and everything)!If it boots fast enough...

But does it reboot and is there a boot manager or what?
[Galaxy S I9000 Android Development] INeedYourHelp:
In case anyone skips it, the link at the bottom of the OP shows a youtube clip of it running. I like how it runs on top of android (vnc to localhost).

Anyways, if anyone does this, I would appreciate feedback on flash in web browser (thinks of Mozilla firefox :D ) My concern are hardware functions like wifi.
[Galaxy S I9000 Android Development] ArminC:
I will try to install firefox on it and see if it can run flash. You are using androids network so you have internet using your mobile connection, so wifi should also work.
[Galaxy S I9000 Android Development] INeedYourHelp:
Thanks!

I wish samsung would just release froyo already. Atm, i hate doing anything major on my phone, knowing that it will all have to be redone.
[Galaxy S I9000 Android Development] RyanZA:
It won't be able to run flash. Why? Flash is closed source! Adobe has to release a binary for linux ARM, and adobe has not released a binary, and adobe will not release a binary.

That is why flash is bad, and the sooner it dies, the better. :)
[Galaxy S I9000 Android Development] INeedYourHelp:
that's what I was afraid of, oh well.

So the only reason to install this is to use programs made for arm versions of linux.... where are they? I tried googling for some arm linux applications and didn't find any website with a consolidated list.
[Galaxy S I9000 Android Development] [[ Cold ]]:
never used an ARM Ubuntu, but in the x86 branch there's 2 options to adobe flash, is there none here?

[Galaxy S I9000 Android Development] BenF1:
Telephony isn't supported, mainly an OS issue. What you're running is a desktop OS it simply isn't designed for phone things such as sms or calling.
[Galaxy S I9000 Android Development] AllGamer:
it'll be cool if they added phone support and 3g support
[Galaxy S I9000 Android Development] carlocb:
Lol it would be... I don't think Google would like spending many years of work to develop a mobile version of Linux (so to say...) and people start using ubuntu on their phones!

Just kidding, I also think that maybe power-management and things like that are not implemented, right? Maybe just "simple" 3G connectivity could be enough... :D
[Galaxy S I9000 Android Development] BenF1:
You'll be right there. The battery will be lucky to last day on a full OS. Its not designed to run on a battery so small.

[Galaxy S I9000 Android Development] Josh_AxeY:
Download keeps failing CRC check for me. Winrar won't decompress the zip.

Also, made the one script to run to boot it... haven't been able to try it though.

Needs to be placed in the same directory as your image.

Also, check out the below app for conveniently running the script from your handset instead of adbing, or using terminal:

GScript:

GScript Lite:

#!/bin/bash
#Script to start ubuntu image on SGS

su

if `test -d /data/local/mnt` ; then
echo "/data/local/mnt"
else
mkdir /data/local/mnt
fi

export HOME=/root
export USER=root
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH

mount -o loop,noatime -t ext2 ubuntu.img /data/local/mnt
sleep 3
mount -t proc proc /data/local/mnt/proc
mount -t devpts devpts /data/local/mnt/dev/pts
chroot /data/local/mnt /bin/bash

When I get home, I'll give the zip another go, and also grab the source for GScript and have a crack at churning out a customised version with the script built in soely for running the image should it turn out to be worth it.

I apologize, it seems something went wrong with the upload. I have uploaded a new zip file and have updated the download links on the blog. I am still not authorized to submit links here so I have to ask you to go to my blog for the download link.
[Galaxy S I9000 Android Development] jodue:
i just read this thread and felt like i had to clarify some things as 90% of the people don't seem to understand what this is!

i have had this running 2 weeks ago from this howto.

first of all. this is not a full OS, so any questions regarding wifi/data/telephony/3g support are completely senseless. this is only a chroot environment which contains the typical programs of a ubuntu/debian system compiled for arm. it has no own kernel or drivers! it DOESN'T BOOT! the internet connection is of course just shared from android, so no need for any wifi or other drivers. and you can do apt-get install xyz to install programs!

yeah, it looks cool and you can do a lot of things you can do on a full pc! regarding performance: the guy from nexus-one-hacks compares it with a slow netbook and i think i can agree with that. but keep in mind that it runs parallel with android!
[Galaxy S I9000 Android Development] INeedYourHelp:
Anything worth while? I tried finding sites that list arm linux programs, but couldn't find anything.
[Galaxy S I9000 Android Development] jodue:
what do you need? did you try

apt-cache search xyz
[Galaxy S I9000 Android Development] ArminC:
This is not for daily use and will probably not be for a long time but it is fun to play with, the performance isn't that great. I do think if you look how fast the smartphones are getting that in a year or two we will be able to run Ubuntu as a full desktop for small tasks. I wouldn't mind if i could connect my phone to a monitor and use it like a pc to internet, do office tasks and maybe some small games.
[Galaxy S I9000 Android Development] Joschi75:
Thanks Armin, It's working now perfectly

Update:

When using your start script I get "test: not found", so "test -d /data/local/mnt" is failing due to missing "test" executable.

Should this be available on the SGS by factory or do I need to install it via a package (or copy it over)
[Galaxy S I9000 Android Development] ArminC:
Try busybox test, if you have the /data/local/mnt folder you can comment these lines.

test is part of busybox

thanks
[Galaxy S I9000 Android Development] ArminC:
There is no auto start, see my post about creating the image to accomplish that. To start your vnc use:

vncserver -geometry 800x480

Password is testing but you can change that if you wish.
[Galaxy S I9000 Android Development] xedamen:

[Galaxy S I9000 Android Development] ethanfel:
it works pretty good, exept arora, who's not launching but i have install chromium (via daily ppa) and abiword, pretty decent.

I will not obviously try Openoffice and firefox, they are too much gtk dependant. I'm using the touchpad mod btw, much more easy to use.

Now, i will try to automatise the vncserver start.

For autostart the vncserver :

When you are in your chroot ubuntu or in the vnc chroot session.

edit /root/.bashrc (with vi or leafpad)

add at the beginning of the file :

and that's all.

it's exactly the same than here. So thanks to them !

Next issue : when i use the "stopa_ubuntu.sh", he can't umount /data/local/mnt, any idea ?
[Galaxy S I9000 Android Development] ArminC:
Or use sed like I showed in my blog:

sed -i '1i vncserver -geometry 800x600' /root/.bashrc

Maybe you have some processes running.
[Galaxy S I9000 Android Development] azazin:
Isn't there a way to dualboot Ubuntu without the use of a PC because honestly the PC actually running Ubuntu, the SGS is just the screen..
[Galaxy S I9000 Android Development] Jim_D:
I think you misunderstood it. This is actually running on your Samsung Galaxy S. Your phone just doesn't natively support the gui, so there is a VNC server set up, to actually view it.
[Galaxy S I9000 Android Development] 19arek93:
