Audio Setup
From Guide
Control how your ASIO device interacts with RiffWorks via the Audio Setup control panel.
ASIO Device
Choose the interface that you will use when recording.
Output Channel
This menu allows you to select the output channel on your interface that you will use when playing your instrument and when listening to what you have recorded.
File Bit Depth
Choose between 16 bit and 32 bit in RiffWorks Standard v2.5.
For more information about File Bit depth and the improved compressor/limiter, please read this press release and this forum thread.
Sample Rate
44.1 Sample Rate for simple setup and CD burning.
Buffer Size
As audio is being recorded into the computer, it is received in chunks of information. A Buffer is essentially a bin that gets filled with audio information. When the Buffer is full, the audio is written to memory or to the hard drive. Then, it is filled again. The Buffer Size corresponds to how big the Buffer is. It is often measured in number of samples. Common Buffer Sizes are 256, 512, and 1024.
The larger the Buffer, the more time it takes to fill it up. This means the audio is being written less often and CPU usage is reduced. However, monitoring latency increases as Buffer Size increases. To decrease monitoring latency, decrease Buffer Size. But a lower Buffer Size means more CPU usage. You must find a balance.
Latency Information
Whenever a digital process takes place, there is an amount of time between the start of the process and the end of it. When recording audio and trying to monitor through effects, the process creates a delay or latency between creating a signal, plucking a string, and hearing that signal. Latency is often measured in milliseconds and can be eliminated or greatly reduced either by monitoring only through Hardware or by decreasing the Buffer Size.
