Description
I use the recorder for doing repeated recordings.
In the first recording, at 2-4 seconds after the start of the recording there is a weird distortion of approximately 0.5 seconds. All the subsequent recordings with the same instance of the recorder are fine. My current work-around is to simply throw away the first recording (which in my workflow anyhow is a test of the audio settings of my mic preamp). Nevertheless it is annoying.
It seems to be different from the known issues #23 (comment) and #6 (comment) since I do not connect a destination to the mixer.
My naive suspicion was a bug in the initialization of the ogg code. However, I then realized that the problem is there with the mp3 and wav encoding as well.
I attached 4 samples packed in a zip file. In the wav case, the distortion is barely recognizable and one might have to listen to it several times.

After a few more tests it seems to be connected with the bufferSize setting. I see the problem with a bufferSize of 1024 (which, oddly enough, is the browser default value of the system). I do not see the problem with larger buffer sizes.
