I've built this little demo that starts the microphone stream, then tries to record a short clip, and when it's done, decodes it and uses it in a Web Audio context, to loop it.

Sometimes it works.

Most of the times, it simply returns a 596 samples buffer. It *is* a valid blob of audio, which *can* be decoded. But the audio contents do not correspond to what should actually be captured. When this happens, the graph looks like this (just in case it tells you something)

This is totally random and I can't find the rationale behind this. Restarting the browser doesn't really make much of a difference.
