Details

This library allows you to communicate small amounts of data between air-gapped devices using sound. It implements a simple FSK-based transmission protocol that can be easily integrated in various projects. The bandwidth rate is between 8-16 bytes/sec depending on the protocol parameters. Error correction codes (ECC) are used to improve demodulation robustness.

This library is used only to generate and analyze the RAW waveforms that are played and captured from your audio devices (speakers, microphones, etc.). You are free to use any audio backend (e.g. PulseAudio, ALSA, etc.) as long as you provide callbacks for queuing and dequeuing audio samples.

Here is a list of possible applications of ggwave with a few examples:

Serverless, one-to-many broadcast
- wave-share - file sharing through sound
Internet of Things
- esp32-rx, arduino-rx, rp2040-rx, arduino-tx - Send and receive sound data on microcontrollers
- r2t2 - Transmit data with the PC speaker
- buttons - Record and send commands via Talking buttons
Audio QR codes
- [Twitter] - Broadcast your clipboard to nearby devices
Device pairing
Authorization

Try it out

You can easily test the library using the free waver application which is available on the following platforms:

Browser demos

HTTP service

# audible example
curl -sS 'https://ggwave-to-file.ggerganov.com/?m=Hello%20world!' --output hello.wav

# ultrasound example
curl -sS 'https://ggwave-to-file.ggerganov.com/?m=Hello%20world!&p=4' --output hello.wav

Technical details

Below is a short summary of the modulation and demodulation algorithm used in ggwave for encoding and decoding data into sound.

Modulation (Tx)

The current approach uses a multi-frequency Frequency-Shift Keying (FSK) modulation scheme. The data to be transmitted is first split into 4-bit chunks. At each moment of time, 3 bytes are transmitted using 6 tones - one tone for each 4-bit chunk. The 6 tones are emitted in a 4.5kHz range divided in 96 equally-spaced frequencies:

Freq, [Hz]	Value, [bits]	Freq, [Hz]	Value, [bits]	...	Freq, [Hz]	Value, [bits]
`F0 + 00*dF`	Chunk 0: `0000`	`F0 + 16*dF`	Chunk 1: `0000`	...	`F0 + 80*dF`	Chunk 5: `0000`
`F0 + 01*dF`	Chunk 0: `0001`	`F0 + 17*dF`	Chunk 1: `0001`	...	`F0 + 81*dF`	Chunk 5: `0001`
`F0 + 02*dF`	Chunk 0: `0010`	`F0 + 18*dF`	Chunk 1: `0010`	...	`F0 + 82*dF`	Chunk 5: `0010`
...	...	...	...	...	...	...
`F0 + 14*dF`	Chunk 0: `1110`	`F0 + 30*dF`	Chunk 1: `1110`	...	`F0 + 94*dF`	Chunk 5: `1110`
`F0 + 15*dF`	Chunk 0: `1111`	`F0 + 31*dF`	Chunk 1: `1111`	...	`F0 + 95*dF`	Chunk 5: `1111`

For all protocols: dF = 46.875 Hz. For non-ultrasonic protocols: F0 = 1875.000 Hz. For ultrasonic protocols: F0 = 15000.000 Hz.

The original data is encoded using Reed-Solomon error codes. The number of ECC bytes is determined based on the length of the original data. The encoded data is the one being transmitted.

Demodulation (Rx)

Beginning and ending of the transmission are marked with special sound markers (#13). The receiver listens for these markers and records the in-between sound data. The recorded data is then Fourier transformed to obtain a frequency spectrum. The detected frequencies are decoded back to binary data in the same way they were encoded.

Reed-Solomon decoding is finally performed to obtain the original data.

C library ggwave_decode: logging of binary data

The ggwave library does logging via printf by default. And will print out the data it has received as if it is text. When sending binary data this can lead to corrupted terminals as some binary data can be interpreted as control characters.

Suggested fix:
-allow disabling of logging altogether
-ideally: don't log via printf, instead allow calling applications to configure logging via their own callbacks.
-make no assumptions about the data, blindly printing the data (except perhaps under a debug log level) can lead to unintended behavior.

Arduino example arduino-tx cant compile: undefined reference to `GGWave::Protocols::kDefault()::data'

Dear Georgi,

I can´t get the arduino-tx example to compile. All necessary files seem to be in place, but its complaining about not having a reference to GGWave::Protocols::kDefault()::data.
Compile log error:

Is this reference indeed missing or am I doing anything wrong?
This is the file/folder structure I´m working with:

ultrasonic sound in JavaScript

Can you guide me how to generate ultrasonic sound( not audible to human) in JavaScript and which parameter i have to change and save/download as a WAV file?

https://github.com/ggerganov/ggwave/tree/master/examples/ggwave-js

Possible to perform simultaneous communications

Hi, I was wondering if someone could point me in the right direction. I've been experimenting with ggwave-js and am trying to create a chat-type project that allows back and forth between a group of people, however, issues naturally occur when two devices are transmitting at the same time, is there any way to get around this?

MT protocol transmit not work on Android app and browser

Hi,
I try to send some words in MT protocol with android app ( download from google play , version 1.5).
When I click send, no sound out.
But other protocol works fine except MT.

Same thing happened at https://waver.ggerganov.com/

I record a video to show issue.

Cannot build pass for ggwave on Windows

I already install msys2 mingw64 and follow below steps to install related libraries.

[MSYS2]
$ pacman -S git cmake make mingw-w64-x86_64-dlfcn mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2

I use visual studio 2022 and open ggwave folder, but it cannot find SDL2. Then it will show error message with "Aborting".
How to resolve it?
BTW, which IDE do you use for development? Or you just use command line to build ggwave binaries?

Difference between Waver protocols

I'm not entirely sure, what's the difference between normal, ultrasound, dual-tone and mono-tone Tx protocols aviable in Waver.
What are the practical benefits and limitations of each of them? Which one should I choose when?

Usage in AV applications for measuring AV desynchronization

Hi!

I'm currently looking into writing an application that encodes a timestamp into a sound signal for the purpose of measuring desynchronization between audio and video (I already transmit data in the video by writing a bit pattern in the video pixels by modifying the luminance).
For that purpose it's important that the library gives me the exact timestamp of the start of receiving the preamble, is that doable?

Web Demo issue

Very great library!

Firstly, for the Web Demo, inside onchange event of "Tx Protocol" combobox , please assign the integer value to protocolId instead of a string value. Otherwise, the "broadcast" cannot work properly when calling _sendData.

Secondly, on MacOS & iOS Safari, the Web Demo can _getText from hearable sound but not from Ultrasound. They both work on Mac Chrome though. Any idea please? Because I want to embed this into a iPhone Cordova app. Many thanks!

Sending files purely via sound

This project is exactly what I was looking for except the limitation for message length and the transfer of files. I suggest the possibility of sending files purely over sound, without any additional type of connection. This could be beneficial in environment without any internet connection and for secure transfer of private data (such as private keys) without any need of LAN network or any internet at all.

Not sure how difficult would be implement splicing data into 140 chars and then sending initial message with number of messages to be transmitted and then checksum in ending message. Or using less then 140 chars plus initial integer for the number of messages. Then receiver would request these messages to be sent again in case of transmission failure.

Hope this makes sense.

problem installing python package

fatal error C1083: Cannot open source file: 'ggwave.bycython.cpp': No such file or directory
error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30037\bin\HostX86\x64\cl.exe' failed with exit status 2

i am recieving this error when installing ggwave in python using "pip install ggwave" . researched a lot but no solution found. maybe one possible solution is install using wheel file but wheel file is not present for ggwave.

same issue with pyaudio but i managed to install it using pipwin install pyaudio.
Another solution is to add ggwave in pipwin package list.

Soundless file

Hi, I might be misunderstanding how to use the library but regarding the ggwave-to-file the readme states that by using the following commands in the terminal we would be able to produce audible and ultrasound files.

audible example

curl -sS 'https://ggwave-to-file.ggerganov.com/?m=Hello world!' --output hello.wav

ultrasound example

curl -sS 'https://ggwave-to-file.ggerganov.com/?m=Hello world!&p=4' --output hello.wav

When I run the ultrasound command with fast or fastest p codes. I still get a R2D2 like output sound in the audio. I was expecting that the file would contain just the inaudible frequencies that the phones would hear but we wouldn't.

I need to produce a file that I can merge into other sounds, so the inaudible property is really critical for me. Is it possible to generate audios without audible content to transmit the messages?

windows receive ultrasound difference

(1) Compile the source code under Windows to obtain waver.exe.

(2) On the same Windows computer, open waver.exe and then open the website address https://waver.ggerganov.com/.

(3) Another computer sends ultrasonic waves with a frequency of 15000-19500Hz.

(4) Waver.exe is difficult to receive ultrasound, but the website can receive it normally.

(5) Change to another computer to receive ultrasound, and the situation is the same.

May I ask if you have encountered similar problems and what may be the cause?
send:

receive:

Can you provide a static lib instead of dynamic .dylib when build the ggwave cli or ggwave-rx cli?

So we can embed the ggwave-rx cli in App easily.

I'm not familiar with cmake, don't know how to modify the config.

Thanks!

Improve the library's logging interface

Currently, we can only change the output file stream through a global static call.
Maybe add stuff like log levels, filtering, etc.

See discussion in #51 for some ideas.

submodule does not work in the released tar.gz and .zip

dear-github/dear-github#214, it seems to be github's problem.

font

Please increase font. I use waver in iphone SE
fonts are very tiny

and clear all messages in one button

Could you make plugin for Flutter

I want to use this libary in my flutter app. I need data over sound, but i don't know how can i make plugin for flutter. Help me

Memory leak python version

Description

While we were checking to use ggwave in our project, we observed memory leaks using valgrind.

Circumstances

When ggwave is imported in a python script and run against python (valgrind enabled python version), we observed these leaks.

Steps to reproduce

Download Python from the original website
We used python version 3.9.2
Compile Python using the following flags:
./configure --prefix=/check_ggwave/python/ --without-pymalloc --with-pydebug --with-valgrind
make OPT=-g
make install
Creating venv using new compiled python in /check_ggwave/python/python3
python3 -m venv .venv
. .venv/bin/activate
pip3 install ggwave
Cloning repo of ggwave and running valgrind on test-ggwave.py:
test-ggwave: https://github.com/ggerganov/ggwave/blob/master/tests/test-ggwave.py
valgrind --leak-check=full --log-file="valgrind_report.txt" python test-ggwave.py

Results

For more details please execute the steps above and check your output, here is a summary:

==18560== LEAK SUMMARY:
==18560== definitely lost: 1,800 bytes in 9 blocks
==18560== indirectly lost: 568 bytes in 6 blocks
==18560== possibly lost: 790,082 bytes in 6,445 blocks
==18560== still reachable: 84,547 bytes in 18 blocks
==18560== suppressed: 48 bytes in 1 blocks

Observations

During our tests we observed that there are no leaks using the C or C++ implementation. Feel free to confirm this on your own system(s) as well.

Conclusion

Based on our analysis we suspect that the cause of these leaks lays in the way ggwave's python implementation is generated (bindings).
But this is only an assumption!

How do I generate two-channel audio encoded data

hi,Whether the PCM generated by GGWave is single-track by default,How do I generate two-channel audio encoded data?Whether the use of two-channel playback will affect the codec effect,thanks

mesh

please add mesh functions, resend data to next node. like meshtastic (why not put this same protocol? every walkie talkie can send message trought this)

Short transmissions fail

Sending strings less than 4 chars from IOS ggwaveapp to command line (using python binding) fail, 4 chars and above work just fine.

ggwave-from-file with empty results on non-48kHz files

When using the ggwave-to-file binary, there is a flag for changing the sample rate of the output, -s.
I would expect the corresponding ggwave-from-file binary to be able to work with the new sample rate. It does not though and produces empty results.
It appears from my superficial testing that ggwave-from-file only supports file sampled with 48kHz.
I don't understand why, because for example the file generated below contains only frequencies of below 10 kHz and no information is missing in the audio file itself, when its sampled at a lower rate.

What I did:

./ggwave-to-file -s44100 -fout.wav -> then typed "abc"
-/ggwave-from-file out.wav
The output looks like this:

Usage: ./ggwave-from-file audio.wav [-lN] [-d]
    -lN - fixed payload length of size N, N in [1, 64]
    -d  - use Direct Sequence Spread (DSS)

[+] Number of channels: 1
[+] Sample rate: 44100
[+] Bits per sample: 16
[+] Total samples: 47041
[+] Decoding .. 


[+] Done

Python - TypeError: encode() got an unexpected keyword argument 'txProtocol'

I installed the Python library 'ggwave' via 'pip' (on Python 3.8.5 on Ubuntu).
The library works for the most part - I was able to send and receive (and even have two devices have a 'conversation' - which was fun ;-) )

But the example code doesn't work - seems unable to select the protocol?

The following code fails:

waveform = ggwave.encode("hello python", txProtocol = 1, volume = 20)

With:

TypeError: encode() got an unexpected keyword argument 'txProtocol'

Removing that named keyword "txProtocol" gets rid of the error.

waveform = ggwave.encode("hello python",volume = 20)

Thanks - great project by the way!
Cheers

React Native

Hi, I'm wondering if it's possible to use the ggwave in React Native and if there is an exemple of it!

ggwave not installing on fedora linux with `pip install ggwave'

So I keep getting this error when trying to install ggwave with `pip install ggwave' on my Fedora Linux machine but running the same command on Linux Mint on my brothers laptop installs fine...
I really need this module to work for me since it seems to be one of a kind in the python world roigh now and I do not have the technical skill to write my own right now...

How to disable Truncating data

How do I disable Truncating data for ggwave python?

Thanks!

It only installs lib/libggwave.so, and no headers

Waver displays wrong data rate for MT protocols

It's 2 times bigger than the actual rate

C library ggwave_decode, no bounds checking

ggwave_decode doesn't accept a size parameter for the output buffer, nor does it honor the gParam.payloadLength parameter, and will write out of bounds beyond the memory given to it.

ppp

Meybe creating a ppp

every laptop and any radios (like baofeng) will be generaly irc server ;-)

question: how about using a Goertzel filter?

I was wondering, did you try using a Goertzel filter? That allows you to compute the power of a single frequency, that is what is used to detect the DTMF tones. This would spare you having to compute the FFT.

Final config for TxProtocols.

Thank you Gwave team, your library is very helpful to me.
However when I use it, I'm noticing that TxProtocols is final in ggwave.h
With default parameters, are these the best parameters? should i edit it or not?

Android

Is there any javascript for android or can I find any source code for your Android app?
It will be very helpful to find one

It is possible to increase max lenght of messages?

Max message lenght is 140. It is possible to increase max lenght of messages? I need 280 message lenght to my project

Is there any way to build to iOS/Android module?

Hi,The demo show this code is so great.
I am not familiar with the C building to iOS/android sdk, there will be more helpful for a example to build to mobile platform.

Thank you very much.

Please add android app able to download from this repository

Or upload it to f-droid.org too.

arduino-rx yields garbled data

Hello Georgi!
My name is Xavier from Melbourne, Australia, and I'm interested in the data-over-sound space.

I've just received my Arduino Nano RP2040 connect and loaded your arduino-rx example code.

Some environmental info:

There's no display, button or speaker connected
DISPLAY_OUTPUT is not defined

Issue description

examples/arduino-rx shows garbled data when sent a message from waver.

This has been tested with both the waver website and android app. Both are setup to transmit [MT] Fastest. The Arduino is set to receive GGWAVE_PROTOCOL_MT_FASTEST.

Steps to reproduce the issue

Open https://waver.ggerganov.com/ and change TX protocol to MT Fastest, and Fixed-length to true, and 16 bytes
Upload https://github.com/ggerganov/ggwave/blob/master/examples/arduino-rx/arduino-rx.ino onto the RP2040
Open serial monitor - set to 57600
Send the message 'test' using waver

What's the expected result?

Turkish characters problem?

How can I use characters like "ğ" "ı" in waver?

exclude the wasm binary from ggwave.js

Ideally the wasm binary file would be a .wasm file

ggwave.js doesn't have much options like waver.js

I am trying to receive a message on the web page (https://github.com/ggerganov/ggwave/blob/master/examples/arduino-rx-web/index-tmpl.html) without any success.

it works great with the waver android app using the following settings in screenshots.

But I could not find the same settings in ggwave.js. Please pay attention to the following console warning "[Deprecation] The ScriptProcessorNode is deprecated. Use AudioWorkletNode instead. (https://bit.ly/audio-worklet)"

Ultrasonic Protocols in .js Examples

Hi There @ggerganov,

I'm developing a web app based on the javascript examples provided here, however I'm not able to receive any messages sent using the ultrasonic protocols. I noticed this was consistent across the .js based examples in the repo. Ultrasonic transfers have been working really well in the Python and C++ versions and with Waver as well. The problem does not appear to be microphone related as I am able to receive ultrasonic messages correctly in Waver on the same device.

Can you tell me if this is a known limitation of the .js binding or if it's something I might be able to fix? I'm not a super confident .js developer so I figured I'd ask before digging in too much.

Basing my initial development on this simple example: https://ggwave-js.ggerganov.com/

Thanks!
