2.3.1.1. Stand-Alone Audio Settings
Device Choose your computer's audio driver protocol in the top Device drop-down menu.
The Mac uses Core Audio. Windows uses ASIO, DirectSound, or Windows Audio. ASIO
provides the best performance with Windows, but requires an external ASIO-compatible
audio interface.
In the lower Device drop-down menu, choose your audio interface, such as the Arturia
AudioFuse Studio or AudioFuse USB interface.
For the remaining options, Mac and Windows work similarly.
Output Channels To hear Vocoder V's audio output, select an output channel from your
audio interface that connects to a monitoring system. The number of outputs you'll see
depends on your interface; this field may show your interface's name. Note that some audio
interfaces use proprietary mixer applications that must be set correctly to hear outputs and
receive inputs. Please refer to your interface's documentation for information on its mixer
application (if any).
Input Channels Select an input channel from your audio interface, such as a microphone
input, to provide an audio signal to Vocoder V's modulator.

♪: If you are using two different interfaces in stand-alone mode, like a laptop's microphone for the
input and a USB interface for the output, you will need to aggregate the two interfaces so that they look
like a single interface to the computer. For Windows, use Windows native drivers (Windows Audio or
DirectSound) as the Device in Audio Midi settings, and all available inputs and outputs will show in the
Audio Midi settings. For the Mac, open Audio MIDI Setup (under Utilities), and then choose the Audio
Devices window. Click the little + sign in the lower left corner; an Aggregate Device box appears, and
you'll see a list of available I/O. Check the interfaces you want to aggregate, and check "resample" for
the secondary interface or interfaces. Now all input and output options will be available to Vocoder V.
For more information, see the in-app tutorials.
Buffer Size and Sample Rate Vocoder V will read these parameter values from your
audio interface. With some interfaces, changing these values in Vocoder V will change the
parameters values in the interface, and vice-versa. With other interfaces, Vocoder V will
change the parameter values, but you will need to close and re-open the interface's control
panel to see these changes. To see the audio interface's control panel, click on Show Control
Panel.
The Buffer Size trades off CPU load with the delay between playing a note on your keyboard
and hearing it. This delay is called latency, as listed in ms to the right of the buffer size.
Lower buffer sizes give less latency, but too low a buffer can produce pops, clicks, or
audio distortion. A buffer setting of 256 or 128 samples should work properly with any
modern computer running a project of average complexity. Projects with multiple virtual
instruments, CPU-hungry reverbs, and lots of plug-ins may require increasing the buffer
size. However, remember that sound travels at about 1/3 meter (1 foot) per millisecond. So,
a 3 ms delay is only about the same amount of delay as sitting a meter away from your
monitor speakers.
Sample Rate is traditionally 44.1 kHz for CD quality, 48 kHz for use with video, and 96 kHz for
"high-resolution" audio. 96 kHz operation requires more CPU power, and is rarely necessary
with most music production.
Test Tone Click Play to send a test tone and verify that the output is going to your monitoring
system.
