 +If the Bare Metal Framework Wizard does not currently show in CCES under **File → New → SHARC Audio Module Bare Metal Project** does not show, try clicking **File → New → Other** and it should show under the C/C++ tab. This is normally a result of installing a new version of CCES after the Bare Metal Framework has been installed.

 +  * **Audio block size** - A smaller audio block size will reduce the audio latency through the framework but it also slightly decreases the processing efficiency.  A larger block size, on the other hand increases the audio latency while also increasing processing efficiency.  Generally, a block size of 16 or 32 is a good compromise.
 +  * **Audio sample rate** - The audio sample rate is number of audio samples present in a second of audio.  As sample rate increases so too does the maximum frequency we can capture (Nyquests theorem).   However, higher sample rates also reduce the number of processor cycles available to process each sample.  Generally, a sample rate of 44.1kHz or 48kHz is a good compromise.
 +  * **Use both cores to process audio** - The framework can use either one core or both cores to process audio.  When using both cores, audio is first processed on core 1 and then it is passed to core 2.  Using both cores effectively doubles the amount of processing power available.  However, it also increases the audio latency.  There's a good discussion on the wiki about the different latencies in single core and dual core mode.
