What is Buffer Size and why is it important?

Buffer Size

When recording audio into your computer, your sound card needs some time to process the incoming information. The amount of time allotted for processing is called the Buffer Size. Often times a smaller Buffer Size is desirable, however not one that is too small. Here's why:

If you have a very large Buffer Size, you will notice a lag between when you speak in to the Mic, and when the sound of your voice comes out your speakers. While this can be very annoying, a large Buffer Size also makes recording audio less demanding on your computer.

If you have a very small Buffer Size, you will notice little to no lag at all between speaking into the Mic and the audio coming out of the speakers. This makes recording and hearing your own singing much easier, however this can also place more strain on your computer as it has very little time to process the audio.

You can fix this by increasing your Buffer Size to something slightly larger. After some experimentation, you will find the right balance. 

You can adjust the buffer size for our stand-alone applications from the following locations:

RX 3: The Audio Tab of the Preferences window will have an option for buffer size.  The Preferences window is accessible from the edit menu.

The T-Pain Engine:  Buffer size is settable in the Preferences window, the Preferences window is accessible from the edit menu.  It is also accessible from within the Sound Check window by clicking the "Sound Card" button.  Sound Check can be run from the help menu.

Once you've found the appropriate balance for your Buffer Size, you will be all set to go.
