Binaural 3D Audio Recorder

Important: Do not close connectivity panel until connections are fully made or fully disconnected. Sometimes panel might look hanged but it takes time to close. I will fix such problems when i will get time. I have many projects to do.

App to utilize two Android devices as sound recorders & mixers. Recorders behave as Left & Right ears. The recorded audios are mixed with some processing to create one 3D (Binaural) audio file.

Pointwise uses:
- Make Binaural Sound (3D sound), Binaural beats or any real 3d sound as it is.
- Binaural audio is useful for many medical and engineering applications.
- Since binaural audio stores direction of sound its also useful in recording audio with direction. Example, while recording a stage show if some sound comes from back will be saved as it is. Good for witnessing sound source.
- Recording forest or other nature sound for relaxing mind with best results due to direction and distance of sound source.
- Its must for VR (Virtual Reality) sounds and VR film making.
- Record sound for VR gadgets like Oculus Rift etc.
- This app is a cost effective alternative to costly hardware binaural recorders.
- Use phones to record binaural and make videos on YouTube. Go binaural, go 3d because that is the future of sound.

I have tried to record audio of 2 devices as close as possible. However even a delay of few microseconds on one device kills binaural quality. Use of Audacity is highly recommended. Without dedicated hardware for timing control making perfect binaural is very hard.

Features:
- Connect 2 devices using Bluetooth or wifi. Control both using any one device.
- Record audio from devices and mix to create binaural audio.
- Use calibration of audio to align both left right audios. Or do this task in PC using Audacity.
- Ogg audio format is used for recording and export.

IMPORTANT:
Android does not allows two recordings from multiple mic at once in one device otherwise i could have made it available in app. There are so many types of devices i cannot test this app on even 4+ devices. I tested on devices i had.

TODO:
- Automatic synchronization to mix left right audios to produce binaural audio hassle free. This one is tough and consuming a lot of time.
- Helping audio to sync using waveforms with amplitude and frequency domain.
- Manual recording mode to record audios without Bluetooth or wifi. Transfer and mix.
- Project management.
- Connection using wifi hotspot.

This app is in workable state and can help anyone to build two recordings and use Audacity to produce final audio. I highly recommend using audacity.

This app is consuming lots of time.
