Minimum buffer size for beEncodeChunk?

Is there a minimum number of samples that should be sent to beEncodeChunk?
I wonder this as my app is recording from a sound input device and playing
to a sound output device, with the option of encoding directly to an MP3
file in the process.  This generally all works fine, but if they switch off
recording and back on again, the encoder can in some situations receive a
much smaller buffer size than the usual 9kb, and this appears to corrupt the
audio being encoded from that time onwards, with a continuous static noise
along with the correct audio.

That is my theory anyway.  Would there be an issue sending 1 sample of audio
to beEncodeChunk?
