I am sending mSBC audio buffer from ESP32 via websocket.
I just want to know if this library can convert mSBC (Wide Band Speech) into Buffer of wav?

How do i export to mp3 instead of WAV

Hi!
Just tried your plugin in my Angular 9 project.
My goal is to take a voice recording, run it though a couple of audio effects using Web Audio API and upload the result to my backend server that stores it.
This plugin comes in when I have my resulting AudioBuffer from the Web Audio API and I want to turn it into a ArrayBuffer and later a Blob/File for upload.

To my surprise, the uploaded recordings are always exactly 6.7 MB and 40s long. If you just recorded a short clip of 5 seconds the rest of the file plays filled out with silent. If I recorded a 50s clip the recording is clipped at 40 seconds.

Are anyone familiar with this problem?

Here's some of my code for reference:

const ctx = new OfflineAudioContext(2,44100*40,44100);
.... Code that adds the Web Audio API effects ....
const audioBuffer:AudioBuffer = await ctx.startRendering();
const wavArrayBuffer = toWav(audioBuffer);
const wavFile = new File([vocodedWavBuffer], 'Voice.wav', { type: 'audio/wav' });
... Code that uploads the file to server ....

Would be helpful for my project to have this on bower
