2.1.2 Loopback Recording (Windows only)
Sample Rate. Changes the sample rate.
You can set the sample rate to 44.1, 48, 88.2, or 96 kHz. A higher sample
rate will increase the fidelity of the recording but will increase the file size
and the amount of system resources necessary to process the audio.
At 44.1 and 48 kHz, all DSP functions are available. At 88.2, 96,
176.4, and 96 kHz, Fat Channel processing will be available on
analog inputs only and the delay bus will be disabled.
Safe Mode. Adjusts the Input Buffer Size.
These modes allow you to adjust the input buffer size
to optimize performance for your computer.
When adjusting the safe mode, the block size will be adjusted
automatically to provide the best performance.
Block Size. Sets the buffer size.
From this menu, you can set the buffer size from 16 to 4,096 samples (Mac), or 64
to 8192 samples (Windows). Lowering the buffer size will lower latency; however,
this will also increase performance demands on your computer. In general, you will
want to set the buffer size as low as your system can safely support. If you begin
to hear pops, clicks, or distortion in your audio path, try raising the buffer size.
Note: When adjusting the block size, the Safe Mode will
automatically change to provide the best performance.
The windows drivers for the StudioLive AR-series mixers provide two virtual
streams that allow you to record the output of on audio application in
another application. Loopback can be useful in a variety of situations:
• Recording the audio from a video game or YouTube
video for a podcast or livestream.
• Recording a vocal in real time over a karaoke track
played from a web browser or media player.
Power User Tip: Because the StudioLive AR-series mixers are class compliant Core
Audio devices, these virtual streams are not available in OS X. However, there
are several third-party applications that provide this functionality in OS X.
