function start() {
  microm.startRecording().then(function() {
    console.log('recording...')
  }).catch(function() {
    console.log('error recording');
  });
}

Seems like Microm class doesn't have startRecording method

Trying to re-play the audio don't work well

• startRecording
• stopRecording
• pause Pause current recorded audio
• getMp3 Lazy mp3 encoding
• getWav
• dowload Forces browser file download
• getUrl
• getBlob
• getBuffer
• getBase64 Get the base64 representation of the mp3 --> Use FileReader.readAsDataURL

hello，i found gh-page demo not work in my local, but chrome worked.

Browser : firefox 43.04

error report:

please give me some help ,tks.

hey, @zzarcon

Great library, any chance to update the npm package with the latest changes you made in the dist/ files?

Hi , i have a problem with recordings that are more than 1 min long , it takes a lot of time to compress in MP3 and on top of that , it blocks the thread (window freeze). i think the usage of web workers for this kind of job will be more suitable.
But i'm not really sure what blocks the thread, because before compression there's a "filereader" call with big chunks of data getting in, needs to investigate more, in the meantime if someone has a workaround for this, it will be a good help, Thanks

Cool library idea. I gave the demo a shot in OS X Chrome Version 47.0.2526.80 (64-bit) and recording didn't work. I see "error recording" in the console.

Ideas?

Using same JS Audio event names.

var microm = new Microm();

microm.on('timeupdate', onTimeUpdate);
microm.on('ended', onEnded);

microm.startRecording();

Encode buffer depending on the recorded data channels:

ld = left.splice(i, i + maxSamples)
rd = right.splice(i, i + maxSamples)

mp3buf = mp3enc.encodeBuffer(ld, rd)

vs

mono = samples.splice(i, i + maxSamples)

mp3buf = mp3enc.encodeBuffer(mono)

Can you check. The demo and dist can't run on Firefox 48.

I have a music application where user can write & play music, I am wondering if I can use this library to record the music played by browser & export it. is it possible to do that using this library. Please help

Until I removed import 'babel-polyfill', I was encountering an obscure error during microm.stop().

I was able to avoid this problem by using babel's transform-runtime plugin instead of the babel- polyfill (v6.9.1).

Gulp build task (partial)

...
        .transform(babelify, {
            presets: ['react', 'es2015', 'stage-2'],
            plugins: ['transform-runtime']  // use this instead of the babel-polyfill
        })
...

Browser

Chrome 51.0.2704.103 (64-bit) OSX

Error details

This line in stop() was blowing up:

self.buffer = new ArrayBuffer(view);

The Uncaught RangeError: Wrong length! error was thrown from this code block:
(found somewhere in /node_modules/babel-polyfill/node_modules/core-js/modules/...)

var validateArrayBufferArguments = function(that, length){
  anInstance(that, $ArrayBuffer, ARRAY_BUFFER);
  var numberLength = +length
    , byteLength   = toLength(numberLength);
  if(numberLength != byteLength)throw RangeError(WRONG_LENGTH); // <<< ERROR here
  return byteLength;
};

And the underlying problem began here:

    $ArrayBuffer = function ArrayBuffer(length){
      return new BaseBuffer(validateArrayBufferArguments(this, length));
    };

In the return line above, this had a value of:

{
  byteLength:  [Exception: TypeError: Method ArrayBuffer.prototype.byteLength called on 
    incompatible receiver #<ArrayBuffer> at ArrayBuffer.get byteLength [as byteLength] (native) 
    at ArrayBuffer.remoteFunction (<anonymous>:3:14) at new ArrayBuffer

}

I was able to use the debugger and breakpoints to track the problem down to the babel polyfill. Commenting out this line solved the problem.

import 'babel-polyfill';

Hi,
I'm trying out this module. The recording works fine but the audio quality is not great. There's a lot of echo and pop noise. This is true for the demo app listed in readme as well. Is there a way to record better quality audio using this module?

Greeting. @zzarcon . I'am a graphic designer. I wanted to contribute to your project and I've designed a logo for your project. If you like it, I'll send you files and pr. what do you think? If you have an idea please share with me, it would be better for me. Thank you. Best Regard

Was the intent to have microm be under a GPL compatible license of some sort? Could you post a license file if so?

How to stop Microm or destroy after recording, because recording icon on tab is not hiding..

I use Chrome 57 on Ubuntu 16

@zzarcon
Thanks

I'm using the dist/microm.js file to integrate Microm in my JSF web application.

It doesn't seem to have the fix made for #24

Could you update dist/microm.js with #25 ?

Thanks
