Changing Bit Rate Session in Sonar X2 !

Here is a short video clip that explains both terms in music.

I record in 24-bit depth.  CD's are 16-bit, so when I mix down it is to 16-bit for burning to a CD.

I also record using ASIO drivers for my interface, and set the Sample Rate for the audio interface to 44.1, and the ASIO buffer size to 64.  This is a good combination for me - I use a Presonus Audiobox 1818 VSL audio interface.

Your interface may or may not need an ASIO buffer size to be larger.  The basic idea is to start with something that works - where you do not have audio dropouts and crackles and stuff, so perhaps start with an ASIO buffer of 256.  This will produce a high latency, but at least there are no dropouts.  So, after you have a setting that works, even though it is a high latency result, you can start dropping the ASIO buffer size, say from 256 to 128, check for dropouts.  If no dropouts, try to drop the ASIO buffer size to 64.  If still no dropouts then you are probably good to go.  If there ARE dropouts, then you have to change the ASIO buffer size back up to the next level (128).

All of the above changes are made in the UI of your audio interface - the ASIO Control Panel.  Some audio interfaces have their own little program for making these changes, and other audio interfaces require you access the ASIO Control Panel from within your Host Recording Program (Sonar).

One more thing, the Sample Rate in SONAR must match the Sample Rate you have specified for your audio interface.  You will find the Sample Rate in Sonar in Preferences>Audio>Driver Settings.

I hope the above helps you to understand,
