org.quietmodem.quiet's Issues

Working sample is better than instructions

Hi,

I realise you have simple looking instructions to get this working. Do you have a working Android sample which demonstrates sending and receiving? It will boost library adoption rates.

Some reliablitiy issue

Hi,
I am trying out this library and noticed - This only works when mic and speaker are just opposite of each other.
I checked out another app "S-Contact" (https://play.google.com/store/apps/details?id=com.totmob.scontact&hl=en") which works fairly well even at longer distance. One reason i can think of is sound produced by "S-Contact" app is louder than what produced by "Quiet".

Is there any way i can increase the volume of sound being produced by Quiet?

P.S: I tested both application on same phone and phone volume set at max level.

Any suggestion from you will really help me.

How well can I expect org.quietmodem.Quiet to work?

I've made a proof of concept app

I've tested with various quiet profiles but can't make it work reliably. It works occasionally with the phones spaced 30cm apart using the audible-7k-channel-0 profile. I've tested other profiles too without much success.

Is there an official demo app for org.quietmodem.Quiet?

Do you have any tips to make my app work better? I'm not sure if I'm using the API incorrectly or my expectations are too high.

Compatibility with C version

Hi there! This is a wonderful library. I've gotten the C version to work reliably between two computers. I have also gotten the Android version to work between my phone and Genymotion. However, my final goal is to transmit a message from a computer to a phone. Here's what I tried:

Download the profiles from here (https://github.com/quiet/org.quietmodem.Quiet/blob/master/quiet/src/main/res/raw/quiet_profiles.json) into /usr/local/share/quiet/quiet-profiles.json.
Run quiet_encode_file audible-7k-channel-0 msg. I chose this profile because it's the one that I got working to transmit from Genymotion to my phone.
Just to test, I ran quiet_decode_file audible-7k-channel-0. It outputs the message as expected.
I'm running these commands in a virtual machine, so I decided to copy the encoded.wav file to my Windows host to play it from there. I play the file in Audacity, but my phone does not pick up the message (I'm using the QuietShare app). I tried to use the same volume and distance from the speaker that I use with Genymotion. It works every time with Genymotion but not with the encoded.wav file. I also ran quiet_decode_soundcard audible-7k-channel-0 in the virtual machine and it works perfectly when I play the encoded.wav file into the computer's microphone. It picks up the message every time.

So, I'm wondering? Are the C and Android versions of the library incompatible or does it have something to do with my setup? Thanks again! Great piece of work.

target specific option mismatch with devel branch quiet-dsp

Brian -- I am trying to build quiet modem. I misread directions and installed current liquid-dsp on my Ubuntu 18.04 system. It compiled and tested well, but cmake for quiet said I had to switch to devel branch. The location specified was obsolete but I believe that the proper version could be obtained via:
git clone https://github.com/quiet/quiet-dsp.git
Is this correct? I cloned it and ./configure seems happy but make fails with gcc complaining about:
dotprod_cccf.mmx.c function 'dotprod_cccf_execute_mmx': …/pmmintrin.h:
inlining failed in call to always_inline '_mm_addsub_ps: target specific option mismatch.
This can be a nasty one to debug. Any thoughts? Steve

How to implement UDP/TCP?

@brian-armstrong in the usage, I could not see the instance of NetworkInterface being used later. Also what is the significance of 169.254.255.255 ?

Some help needed

Hello Brian.

I have been playing with this lib for a couple of hours and I'm stuck with a bug. When the receiver activity is first started, the logcat would show:

W/AudioRecord: AUDIO_INPUT_FLAG_FAST denied by client; transfer 1, track 44100 Hz, primary 48000 Hz

I/System.out: Read timeout

Subsequent start would show:

W/AudioRecord: AUDIO_INPUT_FLAG_FAST denied by client; transfer 1, track 44100 Hz, primary 48000 Hz

E/AudioRecord: start() status -38

I/System.out: Read timeout

From what I understand, the microphone isn't initialized as per this stackoverflow thread, which results in error status -38. But what is causing the read timeout?

The attached is the source code. Thanks for any help.

Complete string is not received at once

I am sending 40 characters long string from webapp (queitjs) to android app (quiet android sdk). However I am receiving this string in parts of 32 and 8 characters. I have used code as stated in samples as below-

transmit.transmit(Quiet.str2ab(cryptogram));

final byte[] buf = new byte[BUFFER_SIZE];
private static final int TIEMOUT = 30;
private static final int BUFFER_SIZE = 1024;

while (keepListening) {
                    long recvLen = 0;
                    try {
                        recvLen = frameReceiver.receive(buf);
                        byte[] immutableBuf = java.util.Arrays.copyOf(buf, (int) recvLen);
                        String receivedText = new String(immutableBuf, Charset.forName("UTF-8"));
                        Log.d("quiet", "run: receivedText: " + receivedText);

x86_64 precompiled libraries are badly linked

I am trying to build my own library on top of this library. When running my tests, the native C libraries (e.g. libcomplex.so, libfec.so) will not load and I get the following error in Java:

java.lang.UnsatisfiedLinkError: /path/to/org.quietmodem.Quiet/quiet/build/libs/x86_64/libfec.so: /usr/lib/x86_64-linux-gnu/libc.so: invalid ELF header

	at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941)
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1857)
	at java.lang.Runtime.loadLibrary0(Runtime.java:870)

	at org.quietmodem.Quiet.FrameTransmitterConfig.<clinit> (FrameTransmitterConfig.java:58)
        ...

Running ldd on the precompiled libfec.so yields this output:

$ ldd libfec.so
libfec.so: error while loading shared libraries: /usr/lib/x86_64-linux-gnu/libc.so: invalid ELF header

(On my system, the correct path for libc.so is /lib/x86_64-linux-gnu/libc.so.6)

Here's some details of my system:

Manually recompiling the libraries seems to resolve the problem. If you think this would be an appropriate solution, I am happy to send a PR with the recompiled libraries.

A/libc: Fatal signal 4 (SIGILL), code 2, fault addr 0xa042c885 in tid 8138 (AudioRecord)

The code for receiving is
receiver.setBlocking(5, 0);
byte[] buf = new byte[1024];
try {
recvLen = receiver.receive(buf);
} catch (Exception e) {
e.printStackTrace();
}

We are getting the Fatal error from the JNI and unable to catch in the java.

Could you please help on solving this issue.

Build native libaries

Is it possible to build the NDK code as part of the build process rather than just including the pre-built binaries?

opensl error code=0002

Hi, i was trying QuietShare sample app on my phone, but when i open it, it show

Nextbit Robin (Snapdragon 808?) support

I built an example app that runs on the Samsung Galaxy S5 but not the NextBit Robin. I assume this is because the Snapdragon 808 is not supported.

Initializing "NetworkInterface" echos sound without send or receive

Intialialize (onCreate())

initFrameTransmissionConfig();
initNetwork();

 private void initFrameTransmissionConfig() throws Exception {
        transmitterConfig = new FrameTransmitterConfig(
                this,
                "audible-7k-channel-0");
        receiverConfig = new FrameReceiverConfig(
                this,
                "audible-7k-channel-0");

        conf = new NetworkInterfaceConfig(
                receiverConfig,
                transmitterConfig);
    }

private void initNetwork() throws Exception {
       intf = new NetworkInterface(conf);
}

once I call initNetwork() sound transmittion plays audio for min 3 times

LoopbackFrameReceiver receives data even if the volume is 0

Created a sample activity and implemented the LoopbackFrameReceiver, LoopbackFrameTransmitter. Then I connected my device to a speaker(via Bluetooth) and start the activity received data in the receiver.

I was expecting that no data will be detected as the volume was 0, but it detects how?

note - I am using the spectrum-analyze app to detect generated sound

when using README example code, exception is thrown

    sSend = new DatagramSocket(new InetSocketAddress("0.0.0.0", 3333));
    // listen on 3334
    sRecv = new DatagramSocket(new InetSocketAddress("0.0.0.0", 3334));

    // don't block for more than 10 seconds
    sRecv.setSoTimeout(10000);

    // get broadcast permission
    sSend.setBroadcast(true);

when using provided code example shown above, this exception is thrown.
