Bug Fix: Hopefully fix flickering visualizations

Now buffer twice as much audio as would be requested for a single visualization PCM/FFT chunk, which should hopefully prevent it from flickering due to running out of audio because of too low latency. Now it buffers up to two chunks at the current hard coded visualization sample rate, which works out to about 186 milliseconds. Signed-off-by: Christopher Snowhill <[email protected]>
