What are Beacodes?
Beacodes are like QR codes. Both can contain short messages that can be read by your mobile device. Unlike QR codes which are transmitted visually, Beacodes are sent using specially crafted sound that is inaudible to human ears, yet fully “audible” to mobile device microphones.
What can I do with them?
They can be used for fully cross-platform ad-hoc communication. Instead of enabling WiFi, Bluetooth, NFC or a QR code scanner, you can just send a Beacode! It will work on all platforms, even on old devices.
You can use loudspeakers or a smartphone to transmit a short message (1-63 bytes) to any mobile device in the area, including Android, iOS and Windows Phone based devices. This can be any text message, an URL, email address, geographic location, etc.
You can even mix Beacode signal with music and other audio content1. Beacodes withstand lossy audio compression of AAC, MP3, Ogg Vorbis and Opus2.
Are there any special use cases for them?
In some cases they can replace BLE beacons, but unlike radio transmitters, our acoustic signals offer some special capabilities. For instance they can be embedded within an audio or video file. This includes sending messages embedded into ambient music or even broadcasting them through TV cable or satellite networks. Imagine sending coupons through your advertisement movie on a TV.
Can I try them?
Of course. You can download our Beacode Scanner app right now and use it to receive the messages. Please go to our demo page for more information.
What about the software?
We provide an SDK for Android, iOS and Windows Phone. Minimum operating system requirements are:
- Android 1.5+
- iOS 6+
- Windows Phone 8+
giving broad supported device coverage. The software we provide can, in theory, support any device capable of recording audio at either 44.1k or 48k sample rate. For more information please read our SDK documentation.
1 Only if the audio doesn’t contain strong high frequency signals, however it happens rarely. We successfully tested our signals with different music backgrounds.
2 Confirmed with 96+ kbps AAC, 128+ kbps MP3, 110+ kbps Ogg Vorbis and 96+ kbps Opus.
