## What is Waver?

Waver allows you to send and receive text messages from nearby devices through sound waves.

This application can be useful for communicating with multiple nearby devices at once. Both audible and ultrasound communication protocols are available. The app does not connect to the internet and all information is transmitted only through sound. In order to receive incoming messages you only need to allow access to your device's microphone so that it can record nearby sounds.

How to use:

- Before starting - make sure the speaker of your device is enabled and disconnect/unplug any headphones. The app uses your device's speaker to emit sounds when sending a text message
- To send a message - tap on "Messages", enter some text at the bottom of the screen and click "Send"
- Any nearby device that is also running this application can capture the emitted sound and display the received message
- In the settings menu, you can adjust the volume and the transmission protocol that will be used when sending messages. Make sure to adjust the volume level high enough, so the sounds can be picked up by other devices
- Tap on "Spectrum" to see a real-time frequency spectrum of the currently captured audio by your device's microphone

File sharing in a local network:

As of v1.3.0 Waver supports file sharing. It works like this:
- Add files that you would like to transmit by sharing them with Waver
- In the "Files" menu, click on "Broadcast". This plays an audio message that contains a file broadcast offer
- Nearby devices in the same local network can receive this offer and initiate a TCP/IP connection to your device
- The files are transmitted over TCP/IP. The sound message is used only to initiate the network connections between the devices
- Waver allows sharing multiple files to multiple devices at once

## Key features

- Text messaging via sound
- File sharing over local network
- Audible and ultrasound protocols

## Frequently asked questions about Waver

### How does Waver send messages?

Waver sends messages by emitting sound waves from your device's speaker. These sounds can be picked up by other nearby devices running Waver, which then decode the message. Ensure your device's speaker is enabled and headphones are unplugged for optimal transmission.

### Does Waver require an internet connection?

No, Waver does not connect to the internet. All information is transmitted exclusively through sound waves between nearby devices, making it ideal for offline communication scenarios.

### What is the file sharing feature in Waver?

Waver allows you to share files by broadcasting an audio message that initiates a TCP/IP connection between nearby devices. Files are then transmitted over this local network connection, not through sound itself.

### Can Waver send messages to multiple devices at once?

Yes, Waver is designed to communicate with multiple nearby devices simultaneously. This is particularly useful for broadcasting information or files to a group in close proximity.

### What are the available transmission protocols in Waver?

Waver supports both audible and ultrasound communication protocols. You can adjust these settings in the app's settings menu to optimize transmission based on your environment and needs.

Since Waver does not use the internet and transmits data solely through sound waves between directly connected devices, it offers a high degree of local privacy. All information is shared only with devices that can physically detect the sound.
