Program crashes when using AudioInput

I am running the example file inputToFile.js. However, when I run node inputToFile.js, it simply outputs the following:
Input audio options: default device, sample rate 44100, channels 2, bits per sample 16, max queue 2
And exits with no indication of what happened.

Using the following command forever --spinSleepTime 1 inputToFile.js,
I get the following message:
Forever detected script exited with code: 3221225477 (0xC0000005)

Apparently this is a windows error similar to SEGFAULT.
Any one know how to fix this?

Segfault Handler dependency causes issues with Electron 8

I am using naudiodon with an electron app, and when running an Electron app, it complains that the NODE_MODULES_VERSION is mismatched. Electron has a NMV of 76. Node 0.12 is 72, and Node 0.13 is 79. This prevents naudiodon from being loaded in electron.

I fixed this locally but just commenting out the 2 segfault handler lines in index.js. Looking at Segfault handler, it hasn't been updated for a while and doesn't support the N-API system.

Not sure what the right path forward for this library is, that's your call, and I understand needing to handle segfaults, but you might need to find another library, or another solution.

Doesn't block me, but thought I would report it anyway.

Repro steps:

1. Get the electron quick start
2. Add naudiodon as a dependency
3. npm install (for things to build)
4. Do a simple getDevices call using naudiodon in the main.js.
5. Run NPM Start
6. You will get a NVM version mismatch error related to Segfaulthandler.

Buffer underflow on Raspberry Pi

Receiving a buffer underflow error when trying to play audio on a Raspberry Pi via USB audio device.

Also, lots of distortion when playing via the headphone jack.

Suggestion from @scriptorian

There is a MaxQueue parameter in AudioOut.cc, currently set to 2. You could try upping that. Next you would need to check the pa callback size - if it is only asking for a small amount of data each time that is going to hurt on the RPi. There is a parameter in the paOpenStream call that can affect this if so.

Duplex audio issue on MacOS

Hello! I'm using MacOS Catalina, Node v12.19.0 and if I run output or input it works properly, but if I use duplex(input and output together) It crashes and log the following:

step 1step 2step 3step 4.2NAPI error in file ../src/AudioIO.cc on line 109. Error 10: An exception is pending
NAPI pending exception. Engine error code: 0
NAPI error in file ../src/naudiodon.cc on line 31. Error 9: Unknown failure

Can anyone help me?

Update:

When I pass nothing on outOptions it emit my input sound with glitches

Ubuntu: getting a string instead of samples in data event.

My app works perfectly on my mac. When I run it on my ubuntu machine (my actual target) the 'data' event returns strings instead of samples.

I've tried it with a couple of different USB microphones. Here's an example of a message that is coming through the 'data' callback:

re/alsa/alsa.confommon:CARD=0,DEVICE=3,CTLINDEX=0,AES0=4,AES1=130,AES2=0,AES3=2m

What's causing this? I am able to record on this PC using arecord, so it appears ALSA is working in the system.

Error using with Windows. "Error: Could not initialize PortAudio: Internal PortAudio error"

I tried to use naudiodon in my Node project. It worked in my Ubuntu, but in Windows I'm receiving an error. I tried to reinstall all packages, but still the same. I'm not sure what's wrong. Follow some prints.

Support for ASIO?

Hey there,

Just wondering if there are plans in the project's roadmap to implement ASIO compatibility? I know that there is a fork that has implemented this successfully. I have tried and tested and it indeed works.

Otherwise, if no one is planning on doing it I'm thinking I could dive into it using the mentioned fork as a start off. Would need to check exactly what the differences are. As far as I can tell, @gschmottlach-xse has used NAN, so I guess the first thing would be to switch it over to NAPI. Then try figure out a way of getting the correct driver to start according to the ASIO host API when an ASIO driver is specified.

I particularly think ASIO support is important when wanting to stream multichannel audio that is higher than the 8 channel limitation put on by windows drivers. I have an application that is required to stream 24 channels to my interface which I can't currently do with the 8 channel limitations.

Crashing with error: "PID received SIGSEGV for address: 0x0" on reinitializing instances

Initially, I'm creating two instances one for input and another for an output with these configs

{
  channelCount: 2,
  sampleFormat: portAudio.SampleFormat16Bit,
  sampleRate: 44100,
  deviceId: -1, // user can change the device using a dropdown menu
  closeOnError: false,
  framesPerBuffer: 1024,
}

and then piping the input stream to the output and starting the stream. This works fine. Now, let's say I want to use a different deviceId for input or output. To do that:

• first, I'm quitting both instances using instance.quit()
• then, reinitializing the instances with different deviceId's
• and finally, starting the stream.

when I do that I get an error saying

    return new portAudio.AudioIO({
        [`${type}Options`]: {

        },
      });
throw new Error('Invalid type');
};

/* This will run when the app is initialized */
const init = () => {

Audio gets cut at the end

Hello all,

I'm facing this issue where the audio gets cut (~1 sec) at the end and can't figure out why it's happening. I hope someone can help me out here please!

Here's the code snippet (it's really just the sample code):

var ao = new portAudio.AudioIO({
  outOptions: {
    channelCount: 2,
    sampleFormat: portAudio.SampleFormat16Bit,
    sampleRate: 22000,
    maxQueue: 1,
    closeOnError: true
  }
});

var rs = fs.createReadStream('./audio/output.wav');
rs.pipe(ao);
ao.start();

Troubleshooting 1:
I've tried to debug and step through the code, however during debugging, the full audio gets played fine and I don't see anything amiss throughout code stepping.

Troubleshooting 2:
I've also played the same file via VLC media player and the audio file was complete (no cut at the end).
Using a different audio file also results in audio getting cut at the end too.

Troubleshooting 3:
To narrow down the issue more, I did the following:

var rs = fs.createReadStream('./audio/output.wav');
var ws = fs.createWriteStream('./audio/output-write.wav');

rs.on('data', (chunk) => {
  console.log(chunk);
  ws.write(chunk);
});

and the file write out complete without audio cut when played via VLC media player.

However when I change it to:
ao.write(chunk);
the output audio gets trimmed at the end.

Troubleshooting 4:
I realized that changing the outOptions.maxQueue affects how much audio is being cut at the end. Setting to 1 and I get the longest audio play, setting it to 2 and it gets shortened more, 3 even more and so on. Setting it to 0 and no audio was played.

Troubleshooting 5:
I've also logged out the close event from the readstream and finish event from ao write stream,
it seems that the close event gets called, then the finish event and that's when the audio gets cut. It does not seem to wait for the audio to finish playing.

I hope someone can help me out with this! Thanks for your time!

Segfault Issues

Hi, similar to a few other users on here I am getting repeated Segfault errors causing node js to crash. I am playing a short audio clip on loop (2s long). The error occurs after ~5-20seconds, but always occurs pretty early on. It only occurs when outputting audio through naudiodon (I have tested piping to a file and error does not occur).

Unlike a most others I do not use electron, It is a custom audio application, with other dependencies, but this error only occurs when the pipe to naudiodon. I recieve a slightly different (and often earlier) segfault error when piping to an audio device which exists, but is not connected to any speakers, which directly references naudiodon, but get a very similar error even if I avoid this use case.

Error when sending to audio device not attached to speakers:

How would I record system audio.

Forgive my ignorance if this is obvious but how would you record system audio?

I tried creating an instance of AudioOutput but I could spot anything on the stream.

Can't enumerate supported hosts

There doesn't appear to be any wrapping of Pa_GetHostApiCount and Pa_GetHostApiInfo, which would allow me to get a list of the supported host apis and the default devices.

How does naudiodon feed PCM data to portaudio? Interleaved or non-interleaved?

Hey there!

Hoping someone can clear this up for me, I've only just got into naudiodon and portaudio. Reading the portaudio c documentation, it says that it reads in multichannel pcm as interleaved or non-interleaved samples and 'automatically performs conversion where necessary'. I'm a bit confused how this concept applies within naudiodon.

Are we required to feed our multichannel files as interleaved or non-interleaved samples? I.e [chan1sampl0,chan2sampl0,chan3sampl0, chan1sampl1,chan2sampl1, chan3sampl1] or [chan1sampl0,chan1sampl1,chan2sampl0,chan2sampl1, chan3sampl0, chan3sampl1]?

Doing some tests, I see interleaving 8 bit samples seems to do the trick.

Now, when streaming more than 8 bit samples, how do we fill a buffer with the correct bytes for each sample? For instance, a 16 bit word, do we fill the buffer [upper16chan1sampl0,lower16chan1sampl0,upper16chan2sampl0,lower16chan1sampl0,... Etc ] or some other way?

Would appreciate any guidance with this!

Trying to understand number of processed buffers per second

Hi

I'm really trying to understand why the following happens.
Any insight would be super useful. 🤪

I have set the following settings from an audio-in readable stream:

sampleRate: 44100
sampleFormat: 16   // 2 bytes per sample per channel
channelCount: 12   // sound card with 12 inputs (6x Left/Right)
highwaterMark = 12 * 2 * 512 // (12 open channels) * (2 bytes per frame) * (512 frames per buffer) = 12288 bytes

I'd think that the buffer-callback gets called +- 86 times per second:
44100 samples per second / 512 samples = 86.1328125

Yet, when I manually count the amount of buffer-callbacks, I get 172, which is exactly the double.
Here's the code how I count the buffer-callback:

let prevTimestamp = 0
let processedBuffersInSecond = 0
this.stream.on(`data`, (buffer) => {
  processedBuffersInSecond++

  if(buffer.timestamp - prevTimestamp > 1) {
    console.log(`Buffers processed in 1 sec: ${processedBuffersInSecond}, ${this.sampleRate} / ${this.framesPerBuffer} = ${this.sampleRate / this.framesPerBuffer}`)
    processedBuffersInSecond = 0
    prevTimestamp = buffer.timestamp
  }
})

# Output
Buffers processed in 1 sec: 172, 44100 / 512 = 86.1328125
Buffers processed in 1 sec: 172, 44100 / 512 = 86.1328125
Buffers processed in 1 sec: 172, 44100 / 512 = 86.1328125
Buffers processed in 1 sec: 173, 44100 / 512 = 86.1328125
Buffers processed in 1 sec: 172, 44100 / 512 = 86.1328125
Buffers processed in 1 sec: 172, 44100 / 512 = 86.1328125
Buffers processed in 1 sec: 172, 44100 / 512 = 86.1328125

Why is this? Am I missing something?

Select input channel

Hi, I'm using a multi input sound card (16 input channels). How can I select the channel I want to record? I mean, how can I set the input source of a stream?

Thanks

A dynamic link library (DLL) initialization routine failed.

I am trying to use naudiodon to stream audio in an Electron.js application. When I attempt to use naudiodon, I get a series of errors related to a dll not being able to be initialized.

Here is my calling code:

const portAudio = require('naudiodon');

// get a list of devices
module.exports.getDeviceList = () => {
  let deviceNames = {};
  for(var x of portAudio.getDevices()) {
    if (x.maxOutputChannels > 0) {
      deviceNames[x] = x.id;
    }
  }
  return deviceNames;
}

The code in my Electron.js html page:

let deviceList = Object.keys(api.getDeviceList());
let optionsHtml = '';
for(var x of deviceList) {
     optionsHtml += `<option>${x}</option>`;
 }
 $('#device').html(optionsHtml);

With api being a reference to the first bit of code.

The traceback:

Part following the ellipsis appear to be irrelevant. (the error echoing up through my code)

I installed naudiodon with npm install naudiodon --save.
I am using the following version of npm and nodejs:
Nodejs: v8.10.0
npm: v5.6.0

And the module (naudiodon) version is: 0.4.6

I am on Windows 10 (64 bit OS)

Please reply as soon as possible. Thanks!

Playing an audio stream from a pipe does not close properly.

If an input stream piped to the audio player ends, the audio player does not end and no finish event is emitted. Probably need to call stream.end() when we're done.

Output silent

Running using the latest stable version of Node on Mac OS X Mojave. I'm routing my audio with Soundflower. I can record my soundcard output with Quicktime with no problem using this routing configuration. Any output from the module whether sourced from mic or Soundflower outputs an empty raw file with no sound.

Getting Audio Decibal Level?

Hello, i hope this is the right library to be using.

I am trying to get the current audio level to detect if sound is currently being played from the speaker (like when a youtube video is opened, i can detect that)

I am not sure if this library has an example for that scenario so I wanted to ask.

Record error when using Soundflower(2ch)

Hello,

When I use Soundflower(2ch) to record audio, sometimes it works well, but sometimes it prints an error and cannot receive any audio data:

||PaMacCore (AUHAL)|| Error on line 2490: err='-10863', msg=Audio Unit: cannot do in current context

What's causing this? Or is there any way to capture this error? I listened error event, but it was not triggered.

Thanks

Big delay when using bluetooth microphone (airpods)

I'm using this library to record the user's audio input stream. With a built-in microphone it's perfect. However when I use my airpods microphone, there's such an initial buffer/delay that the first 1/2 seconds of talking are cut off. Any ideas on how to improve this?

I've tried using ai.on('data', buf => console.log(buf.timestamp)); to determine when the audio input actually starts collecting data, but this seems to first get called way after the audio begins to be captured.

Code for reference:

  ai = new portAudio.AudioIO({
    inOptions: {
      channelCount: inputDevice.maxInputChannels,
      sampleFormat: portAudio.SampleFormat16Bit,
      sampleRate: 44100,
      deviceId: inputDevice.id,
      closeOnError: false 
    }
  });

  // Create a write stream to write out to a raw audio file
  const ws = require('fs').createWriteStream(`tmp/${title}.raw`)

  //Start streaming
  ai.pipe(ws);
  ai.start();

Allow setting framesPerBuffer through js api

Currently the framesPerBuffer is hardcoded in PaContext.cc (it defaults to paFramesPerBufferUnspecified, but is hardcoded to 256 on arm).

Could framesPerBuffer by exposed on the js api in/outOptions part?

This would allow experiments without needing to recompile the C++ module each time.

Problems when installing on Windows

Did a fresh install of windows yesterday(2018-12-06) and were having some issues installing this module.
System info:
Windows 10 Pro 64-bit
Version 10.0.17134 Build 17134 (1803)

I installed nodejs, python2, vscode, git and github desktop on the fresh install. Albeit that i did get other errors before i reinstalled.
There seems to be some unmentioned prerequesites for this module, and im not sure if you are aware of this?
First i had issues because i had python3 and not python2 installed(this was before i reinstalled windows!)
You can see the first error i got here:

This should be fixed by installing python2 and having it in your PATH. I am not sure if you need to remove python3 from PATH before this will work.

The second error goes something like this:
MSBUILD : error MSB4132: The tools version "2.0" is unrecognized. Available tools versions are "4.0".
The solution for this seems to be that you either have to install a redist that supports the mentioned version. Or you can download and install Visual Studio Community 2017 and add atleast one of or both these Workloads: .NET Desktop Development and Desktop Development with C++.
I added both.

After that the installation worked perfectly with no issues.

Playback on osx is high-pitched

Tried with several files, samplerate is set fine .. but playback is pitched very high, so samples play fast.
No errors or messages of any kind ...

Anyone met something like this?

Update the README with a list of available events and methods

I was hoping to get a bit more of an idea of the event handlers that I can hook into.

For example, I want to created a recorder that starts whenever an audio signal is received from a usb device. Something like:

ai.on('audioSignal', () => {
    // Start recording
}

Is there anything like that in portAudio? Or is that more something I would have to create an wrapper around the USB audio interface?

naudiodon stops working after about an hour and a half

I have been using naudiodon for input and output for a desktop application built with Electron.
Everything works fine at the start but after an hour and a half or so the output audio stops and the application stops working. Below is the stack trace outputted by the electron application. Does anyone have an idea about what is causing the problem?

Get exact timestamp of audio recording start in with PortAudio

Basically, we record audio and video separately, but afterwards we still need to sync them together, and in order to do that, we need exact timestamp of audio start, and by piping into AudioIO or listening to data events we not getting it right. Port Audio has some delay in releasing chunks.

Fully described problem here.

Support for windows loopback, record the output of soundcard

Hi,

Can you add support for windows loopback? Need the ability to record the output of soundcard.

One fork of Pyaudio supports this. Could you please add support for this?

intxcc/pyaudio_portaudio@aa30196

Or if you could guide me how to do this on my windows machine, I'm happy to send PR

Generates squeaks

When i try the sample program , it generates squeaks instead of the sound. I am using an external USB speaker to play.

Library not loaded: /usr/local/opt/portaudio/lib/libportaudio.2.dylib

Am running this in my app

import portAudo from "naudiodon"

console.log(portAudo.getDevices())

and get the following error

Input Overflow Error when stream is not read from

Is there a way to ignore the input overflow error thrown by a stream such that the stream is not closed, and continues to work?

My application records system audio and broadcasts it over a network; sometimes due to network issues or no clients listening in, the stream is not emptied quickly enough, and it overflows and closes, necessitating a server restart for it to work again.

Can the exception be ignored? I remember older versions of naudiodon not closing the stream when an input overflow error occurred, allowing the program to continue running

Record system output

Hi,

Basically I want to record and stream the system output of the host. If this is possible how do I modify the inoptions to point to an output?

Thanks

Is there a way to convert the recorded .raw file to a .wav file?

I realize that the README here says:

Note that this produces a raw audio file - wav headers would be required to create a wav file.

However, do you have any idea for how I should go about this? (Using JS, not a command line tool such as SoX, unless there is a wrapper for it)

Uncaught TypeError: Path must be a string. Received undefined

On the latest version of naudiodon, getDevices will throw an exception. I'm on macOS Sierra if that is any help.

var naudiodon = require('naudiodon')
...
console.log(naudiodon.getDevices()) // Uncaught TypeError: Path must be a string. Received undefined

I hope you'll be able to help - I'm looking very much forward, to use your great addon.

Reading from microphone every x seconds

Thanks for sharing this great package! I am currently trying to read data from the microphone every x seconds using the code below, where I just try to print out the length of the buffer obtained from the microphone:

const setTimeoutPromise = require("util").promisify(setTimeout);
const AudioIO = require("naudiodon").AudioIO;
const interval = 1;
let handleMICPromises = [];
let readPromises = [];
let microphoneOn = false;

const options = {inOptions: {channelCount: 1, sampleFormat: 16, sampleRate: 8000}};
const microphoneStream = new AudioIO(options);

function handleMIC(resolve, reject)
{
    if (microphoneOn)
    {
        const readPromise = setTimeoutPromise(interval * 1000);
        readPromise.then(read);
        readPromises.push(readPromise);
    }
    else
    {
        microphoneStream.quit();
    }
    handleMICPromises.shift();
    resolve();
}

function read()
{
    readPromises.shift();
    const handleMICPromise = new Promise(handleMIC);
    handleMICPromises.push(handleMICPromise);

    if (microphoneStream.readable)
    {
        let buffer = microphoneStream.read();
        if (buffer !== null)
        {
            console.log(buffer.byteLength);
        }
    }
}

process.on("SIGINT", () => {
    microphoneOn = false;
    Promise.all(readPromises.concat(handleMICPromises)).then(()=> {process.exit();});
});

microphoneStream.start();
microphoneOn = true;
const handleMICPromise = new Promise(handleMIC);
handleMICPromises.push(handleMICPromise);

When I try to run the above file, it prints out 16384 for the length of the buffer every 1 second. This seems about right, since audio sampled every second at 8000 samples per second with a sampling format of 16 (2 bytes) will be about 16,000 bytes. So far so good.

However, when I try to set the interval at the beginning of the code to, say, 5, I still get the same buffer length of 16384 printed out. This shouldn't be right. According to the NodeJS documentation on read(), read() should read everything that's in the readable stream. But this is not happening in this case.

Let me know if I'm missing something, or if this is a possible bug. I also looked at the resulting audio file when I parse and save the results of the buffer to a WAV file, and I only get 1 second worth of audio for every call to read() even if I make that call to read() every 5 seconds.

Thanks in advance for your help!

input overflow error when thread blocks

I am trying to capture input audio from device. This works great when the thread is free, but I have noticed that if the thread blocks for a short while, this can cause portAudio status - input overflow to be thrown and then the stream stops.

Managed to get the scratch/inputToFile.js to reproduce this by adding a fake sleep (loop that takes a long time to complete).

// add to scratch/inputToFile.js
var collection = []

setInterval(() => {
  for (var i = 0; i < 1000000; i++) {
    collection.push(i)
  }
}, 1000)

Then after a few seconds, you should see:

Error: portAudio status - input overflow 
    at Error (native)

I tried messing with the maxQueue value:

naudiodon/src/AudioIn.cc

Line 218 in d0d3146

mInContext = std::make_shared<InContext>(std::make_shared<AudioOptions>(options), InCallback, 2);

But still hitting this.

Any ideas?

V1 installation is OK.
Is there something I am missing ? node-gyp is well installed, tested with different node version.

Thanks !

Electron libportaudio image not found - binding.gyp enhancement

I got hit with the Image not found error for libportaudio when I packaged up my electron application and ran it on a different machine, application ran fine on the development machine though. After digging through some documents about node-gyp, I was suggested to look for the linker section of the naudiodon.node binary and found out that the LC_PATH was set to an absolute path of the build/Release path on my development machine. What I did to make it work was to change the OTHER_LDFLAGS of OS=="mac" to "-Wl,-rpath,@loader_path/" which tells the linker to look for libraries relative to the binary file location.

Error from calls when running inside a docker container on RPi3

I am doing the following from within an ubuntu container running on an RPi3 Raspbian...

        var portAudio = require('naudiodon');
        var devices = portAudio.getDevices();
        var devices_str = ""
        for (device in devices) {
          temp = devices[device]
          if(temp['id'] == requested_device) {
            response_string = "<pre>" + JSON.stringify(temp, null, 4) + "</pre>";
            response_string += "Reading Data : <a href=\"socket_audio?device_id=" + temp['id'] + "\">" + temp['name'] + "</a>"
          }
        }

I am seeing the following coming out of the nodejs server

No support for IEEE Sample Format.

I have a small script just loading in a single .wav file, mostly just a copy and paste from the README and the sound quality that outputs to my speakers is terrible. It's mostly screeching.

I've confirmed that the audio file was saved at 44100 Hz with 32 Bit Float (IEEE), 2 channels. So I've set up the outOptions accordingly.

var ao = new portAudio.AudioIO({
    outOptions: {
      channelCount: 2,
      sampleFormat: portAudio.SampleFormat32Bit,
      sampleRate: 44100,
      deviceId: -1 // Use -1 or omit the deviceId to select the default device
    }
});

The only way I could get the audio to behave nicely was to convert it to 16 Bit and then change the sampleFormat to SampleFormat16Bit. Is this intended by this library? Or is there some lower level detail that I am missing? Playing this same audio file through something like Audacity sounds just fine.

Edit

So from my understanding, this library is expecting Signed 32 Bit Integers, not floats at all. Yikes!

Confirmed within PaContext.cc Line 226, the switch statement looks for a parameter of 32 and then assigns a Sample Format of paInt32 to the context. This lib should be able to distinguish between 32 Bit Int and 32 Bit Float which could mean a more robust parameter coming in from the node side or a new implementation of enums here that map to a wider range of PaSampleFormat enums.

Does this binding support full-duplex (simultaneous input/output) PortAudio streams?

I see that it supports, separately, both input and output streams. What is not clear is whether it support full-duplex (e.g. both input/output) audio streams? Trying to create separate Input and Output audio streams with the same device ID fails. Can this be easily achieved via some other mechanism?
