Comment (by jyavenard):

 I'm actually thinking of doing it the following way:

 make the audiobuffer 32 bytes bigger than what it currently is. Then stop
 using the constant kAudioRingBufferSize to determine the length of the
 buffer, instead use a dynamic variable.
 When doing a reset, the length of the audio buffer would actually be
 changed so the length between raud (which is now the new waud) and
 kAudioRingBufferSize is now a modulo of bpf.
 That way there is no thread/locking issue, and we will always be able to
 fit everything to the end of the buffer.

 Doing so would actually remove the requirement of having such a big audio
 buffer, simply because it needs to be a multiple of all the possible bpf
 values
