nodejs error TypeError: Cannot read properties of undefined (reading 'bind')

[Goddard]

feeding chunks to resampler errors out immediately -

const { create, ConverterType } = require('@alexanderolsen/libsamplerate-js');

just importing this causes the error let resampler = await create(nChannels, inputSampleRate, outputSampleRate, { converterType });

I'm happy to help, but I can't really help you without more information. Please either consider closing this issue + reopening using the bug report template I've provided, or specify more details about your environment. Node version, LibSampleRateJS version, OS, etc.

About all I can say right now with what you've provided is:

• It looks like libsamplerate-js is failing to load the wasm glue code, which suggest you're using an older version of the lib
• I've just created a sample node project, installed, and loaded lib correctly using your code

Seems to me there might be an older version in use, but please provide more info and we can figure it out.

[Goddard]

I used this command as stated on the readme today to install.

npm i @alexanderolsen/libsamplerate-js

I am using node version 16.20.0

[Goddard]

I also tried building from source with the docker image and got the same issue.

[aolsenjazz]

What operating system are you using? If I run the following:

nvm install 16.20.0
nvm use 16.20.0
mkdir lsr-test
cd lsr-test
npm init -y
touch index.js
npm i -S @alexanderolsen/libsamplerate-js

edit index.js:

const { create, ConverterType } = require('@alexanderolsen/libsamplerate-js');

and run

node index.js

The program completes without error, so this must be an environment issue. Please provide as much environment info as you can. What OS/version are you using? Is this in the browser, node AudioWorklet, etc? Please double check node version with node -v

[Goddard]

Manjaro(Linux) it is rolling so latest.

I am running it in the cli so node. I also use nvm.

But this is running in a docker instance that is ubuntu. node --version v16.20.0

[aolsenjazz]

Thanks. Does the CLI example work for you? I don't have a Linux installation, but I need to install one for another project anyways. Will bump that up in my to-do's so I can check this out too. Thanks for verifying node version.

[aolsenjazz]

I've fresh installed Manjaro Kernel version 5.15.131 and the following works as expected. Same process - init empty project, install, create index, execute using node 16.20.0

const { create, ConverterType } = require('@alexanderolsen/libsamplerate-js');

(async () => {
  const inSampleRate = 44100;
  const outSampleRate = 96000;
  const nChannels = 1;
  create(nChannels, inSampleRate, outSampleRate).then((src) => {
    const d = new Float32Array(44100);
    const resampled = src.simple(d);
    console.log(resampled.length);
  });
})();

Inspecting the trace you got, the .bind() statement is being called on console.error. So for whatever reason console.error is not defined in your env.

Sorry to say, not sure what else I can do for you here.

Closing as this seems to be an environment issue. Feel free to followup and we can reopen
