Binaural 3D sound recorder app using 2 devices as mic. - Android Apps and Games

Hi,
I have been using xda forum for long but wanted to share my own app(s) now. I completed my binaural audio recorder in January 2016 and published on PlayStore.
Many of us might have listened to some kind of 3d sounds like virtual hair cut etc. Without using expensive hardware anyone can record binaural 3d sounds using 2 android devices. It uses 2 devices as left right ears and mixes to build final output. Features -
- Connect 2 devices using Bluetooth or wifi and control both phones to start and stop recording.
- With wireless connection pressing start and stop affects both devices. Means operate with only one device!
- Records at 44.1KHz 16Bit OGG by default
- Limit of recording is decided by battery and disk space.
- Handles most of tasks automatic.
- Tested on Moto-G, Redmi phones, Yu Yunique, Samsung Galaxy 3 Mini. However due to hardware fragmentation it might fail to work on some devices.
Its an ad-supported freeware in nearly a beta stage due to wifi connectivity operations. Due to no access to universal time source the 2 recorded audio are many times out of sync means some sound plays earlier on a device. This can be calibrated using mixing panel.
I am working on many projects and suffering app discovery problem making almost no downloads of my apps.
Since i am not allowed to post links i am posting how to download. My app can be searched on play store by GamesGreh Binaural 3D Audio recorder or visiting ourinnovativemind dot in or gamesgreh dot in.
Anyone interested in 3d audio please take a look at this app and do let me know any problems you get.

Found this app while searching binaural recording on Android. I downloaded it on two phones but I can't get it to work. Did you give up on it?

Hi,
I stopped working on this project after 2-3 months as i started my other projects. This project required extremely precise timing sync between devices. Due to delay in communication the binaural effect used to fail and it required user intervention for shifting audio channels to get better binaural output.
I use my phonw which has 2 microphone at opposite ends and records stereo +(kind of binaural). I think using hardware is the best way to record binaural. Actually real 3D is not possible by 2 earphones until full research is done how 3d perception in achieved by mind. There is role of other body parts also in 3d. Not just ear passage.

[Q:Android] A way of streaming sound from microphone over Wi-Fi

Hey there, how's your day going?
Now, this is not a can-it-be-done kind of question, because the IP Webcam app already does just that - it exposes the audio from microphone via http on localhost:8080/audio.wav and .ogg for anyone to access.
The thing is that the app also does a pleyhora of other things - most notably video streaming, which makes the app one hell of a bad boy when it comes to battery consumption. And not only that, the audio streaming - as implemented - is severely delayed and the format / compression used can't really be adjusted to alleviate that issue, which in turn renders it impossible to turn the droid into a remote microphone (which would be an awesome thing to do ).
And since I don't think the author has ever released a source code (I stand to be corrected), I'm asking whether there is an app dedicated just and only to audio streaming (obviously couldn't find any, hence I'm asking) or whether I'll have to act a dev once again.

[APP][2.1+] Calls Recall

"Calls Recall" is a non-disruptive call recorder that records calls in the background without user attention. Minimalism is a goal.
Whenever calls are made or received, the conversion is recorded automatically and stored in external storage.
How many temporary recordings to keep is set by user in the setting screen. Old recordings are replaced by new ones.
User can browse recordings and set recording as saved so it will not get replaced.
User can play and delete recordings.
* If you use headphone, you can barely record the voice from the other side, because this app use phone MIC to record (as of now, there is no other commonly supported audio source).
Hello people, this app is on Google Play. Feedback is welcomed.
I wanted a call recorder and downloaded a popular one but it's interface is too complex and even failed to record anything after like 10 presses of things. So I sit down and wrote my own. I come from traditional UNIX world and believe tools should be simple and do one thing well. If people want further process the result, they can adopt another tool in the pipeline.
My disappointment is audio source VOICE_CALL is not implemented by most phone manufactures, and I have to record from MIC. If you have other choices that make it works better than now, I will appreciate.
Thanks

[APP][3.0+] Around Sound - Have your phone pay attention while you enjoy your music

Update (4/11/2017): Updated the app to use the Superpowered audio library. Performance is greatly improved. Lag is pretty much gone.
This was my first app and recently just overhauled it with a lot of the updates I had been doing to Wave Control. I've decided to take this out of incubation in the device specific forums and put it fully out there. All feedback is appreciated!
Around Sound allows you to listen to music, watch movies, or play games and still be aware of your surroundings. It's meant for when you're using sound isolating earbuds like Shure or others that are basically earplugs so you have no idea what's going on around you.
It uses the mic on your headset or phone to listen around you. You set how loud a noise needs to be to trigger it. When a loud sound is detected, it pauses your music or movie for a timeout period. During this time, it feeds the outside sound through to your headphones so you can hear what's going on. After the timeout period it then resumes playback.
With games, you can use the non-pause mode which will overlay the outside sounds on top of the current audio. Usually the game audio will lower itself during this time. I would really like for games to support the pause feature. I've reached out to some developers but need everyone's help to request the feature be added to their favorite games.
Play Store Link:
Free Version
Some known issues:
1. Audio lag - when the outside sound is fed through there's about a 500ms delay. It's a known issue with Android. It's rumored to have been fixed in Jelly Bean (or there's some low level API's available to fix it) but I haven't had a chance to play with it yet. Finally fixed! Practically realtime now!
2. Bluetooth Mic Option - Currently only works with mono headsets and not the AD2P kind, adds lag
Some use cases:
- At the office: pause your music automatically when someone is trying to get your attention
- At home: Don't miss door slams, children crying, your dog barking, or other warning signs

- At the airport: Relax at the gate and have your music or movie pause when the gate announcements start

- Anywhere relatively quiet where you want to know if something happens around you
Permissions Needed:
Network Communications: Full Internet Access (For Ad Supported Version)
Phone Calls: Read Phone status (shuts off the audio processing during calls)
Hardware Controls: Audio Settings, Record Audio (to use the microphone, no audio is ever stored)
Coarse Location(Not GPS): For Ad Supported Version
Write External Storage: For Ad Supported Version
Billing: For in app upgrades
Bluetooth: For Bluetooth mic feature
Broadcast Sticky: For Bluetooth mic feature
Limitations:

-For Pause Music Mode: You can't be in a really loud environment otherwise the microphone input will be maxed out and there is no way to detect a louder sound. Use Street Mode instead
Developed on a Samsung Galaxy S7
I played with this a bit in a few of its earlier incarnations and I have to compliment you on the app. One thing I've wondered -- instead of muting the underlying app, would it be possible to play what the microphone picks up over the top of whatever being played?

i guees that is not possible ...hardware limitations
anyway if it is...would be a great addition
I hope someone can explain this to me. I'm not doubting it's a hardware limitation, I just can't understand what sort of hardware limitation it might be.

Yeah, it's possible. If you uncheck pause mode, it'll play over the other app. The way it's setup now, depending on the playing app, the music/movie might dip in volume. Alternatively there's Street Mode in the Pro Version that will play all sound above the trigger on top of your music/movie.

Woo hoo! Cool, thanks! Pro, here I come.
Any idea when you think you might be able to look into that lower latency JB API?

This is so genius! Installing now!
I bought Pro this morning and used it on my walk. Worked like a charm!
It was pretty bright out and my screen couldn't brighten enough to let me see the trigger slider. A suggestion: how about adding +5 and -5 buttons so I can adjust the trigger level without having to see the slider? I don't mean remove the slider, I mean add +5 and -5 buttons.
Got the pro just to support the Dev. Great idea and great work. Keep it up man!
A little coverage on the portal for you

Sounds perfect....
i saw this while ago and was going to use it but deleted it by accident and than forgot about it this has reignited me to use it now ill download it later.
any news on the bluetooth issue as i have bluetooth headphones and there not mono and was wondering if it work well or not with em?
Wow...this is great. Thank you.
I like the sound of this (No pun intended) but I've only got bluetooth stereo headphones with a mic. so I'll have to wait until it supports them.
App2SD would be nice ...

I don't have a set to test it with but I've gotten mixed feedback. Some stereo ones do work and some don't. Or.. it may be a particular phone's bluetooth implementation since it seems more like a bug in Android than a headset specific issue.
Please give it a try and let me know if it works!
Will this save me if I end up in the middle of a shoot out, and I have in noise canceling headphones? As bizarre as that sounds... I'm paranoid lol

Possibly... but I make no guarantees
New Angle
So after un-intentionally (really, I swear!) ignoring my girlfriend while playing a game, I realized... I could use Around Sound with games.
So far the non-pause mode works pretty well with the games I play. I'm reaching out to some other developers to include the ability to pause when asked by Around Sound.
I need people's help to request their favorite game dev's to support auto-pause with Around Sound

Audio Recording App with Monitoring/Live Recording/Active Listening????

So I need to record a track, and I have a 3.5mm splitter plugged into my Droid Turbo and the input and headphones connected to the splitter. Sound comes in and out just fine, I can record and playback without any problems, but I cannot find and Android app that has a good monitoring feature; meaning while recording the phone simultaneously outputs everything it inputs, allowing me to listen to myself through the headphones while recording. I say a good monitoring feature because there is one app, Miidio Recorder, which claims this feature, but has extremely high latency and almost a whole second of lag. There are many ios apps that I have personally used which can accomplish this perfectly, but I cannot find one single Android app.
The apps I have tried so far are:
Miidio recorder
Fl studio mobile
Caustic 3
Pocket studio
At least 5 or 6 different audio recording apps.
If anyone knows of or can code a simple app that does this I would greatly appreciate it.
Thanks
[EDIT] this is my first post so if I'm supposed to like add anything or something please lmk
Wow, almost 5 months, no reply. leaving a reply because I too would like to know the answer. Is it an Android issue or just plane dislike of developers for Android owners??

Music recording sounds very bad

Hi everyone,
It is common knowledge (I hope) that when you try to recording a video or just a simple audio file with some music (for example a song during a concert or, in my case, an audio while I play the guitar and I sing something) everything sounds very very badly! Now, my question is:
Is it a software or hardware problem?
This is important to me because I use very often my phone for these kind of things, mostly during a concert. I've tried to look for something about it but I could't find any useful answer. I hope it's a software problem and it can be fixed just changing a ROM. I'm using the phone as stock now. With no root and, of course, no custom ROM. Thank you
Wtf, completely disagree...
Em, I am a musician, and I wouldn't really agree. There's no way that recorded music is better than live music cause obviously, the live one is 100 times much more powerful.
Do you have a case on it?
(Lol, don't cover any of the mic ports with your fingers and keep people, objects out of the sound path.)
Are all the mic ports open and free of debris?
What file type are you recording in?
I wouldn't expect miracles from any smartphone for HQ sound with the built in mics. Some do fairly well.
