♪ What does it do?

Air Waves is a "one to many" local radio broadcasting service which could be used for many things such as live translations for an audience, a baby monitor or a 2-way intercom/walkie-talkie.

Prior to creating this app, we had looked into alternatives. The translation system we needed for Ecclesia Mission Hills church (translation service) was almost $8,000. That included only a transmitting station, microphones and 4 headset devices.

With Air Waves, we paid (in $AUD):

• wireless N150 router ($60)

• $120 for x2 cheap Android phones to test our setup with

• $20 for x2 in-ear Sony headphones

• $0 to bring your own additional listening device

So for $200 we've provided the same service which an $8,000 system would have, except Air Waves is easier to set up and far cheaper if we need more headsets.

♪ How to use it?

It doesn't get much simpler than this!

• Broadcaster: Click on the microphone to start broadcasting immediately.

• Listener: Simply click on the headphone icon and choose the channel (or language) you want.

Note: all devices need to be on the same WiFi network.

♪ Advanced usage

• Press menu to set your device name

• Press menu to enable/disable audio playback via headset (for speaker)

♪ Hardware required

• At least 2 Android 4.1+ devices

• A router with wireless capabilities (preferably at least N standard)

• (optional) Some headphones and/or microphone for better audio quality

♪ Notes

I've only tested on a handful of phones, simply because I can't afford to buy every phone in the market.

Below are the phones I've personally tested and works with Air Waves:

• HTC Droid Incredible 2

• HTC One X

• Nexus 4

• Samsung i9000 / S2 / S3 / Note 2 / S 3 Mini / S4

• Sony Xperia X10 mini / Z1 / Z3 / Z5

• Xiaomi Mi 2S

• ZTE T12 / Telstra Uno

♪ Some additional advice

• Lite version can only broadcast for 2mins. You can get the full version here: https://play.google.com/store/apps/details?id=twig.nguyen.airwaves.pro

• Both broadcaster and audience must be on the SAME wireless network.

• Each listener will use approximately 20Kbps, so please ensure your broadcasting device can handle the given number of listeners. See below for a detailed breakdown.

• There is noticeably less audio latency on Android +4.1 devices as Google has fixed up some audio processing issues and again in Android 6

• If you use a hands free microphone, the microphone used will affect recording quality. (Garbage in = garbage out)

• Each broadcasting device has different methods of noise cancellation. Pick the one which works best for you.

♪ Some features on wishlist

• automatically reconnect to server

• use non-blocking IO
