Promisify encodeWav.js ?

[jmarcosfer]

Currently encodeWav expects a callback that will be passed the blob after a 30ms timeout.

Why is the timeout necessary in a function that appears to be otherwise fully synchronous? I tried swapping the setTimeout for a simple return blob; and it works fine.

Assuming there's some asynchronicity that has to be waited for, why not return a promise that resolves with the blob?

In my use case, I'm encoding many different chunks of audio and then putting the blobs into a zip file for download, so I have to wait for all blobs to be returned. The callback was not a practical solution for me, but maybe other people using this library typically don't have this problem and are okay with the callback solution.

I could submit a PR with a very simple change to promisify encodeWav, but I wanted to understand the library's rationale first.

Thanks!

If return blob works why is using async or Promise necessary?
