On Windows you have the ability to use different audio driver standards, WASAPI or ASIO.
ASIO is a proprietary audio interface standard which bypasses the operating system’s mixing kernel, so providing lowest latency direct communication between computer audio software and hardware. Some Hardware manufactures supply an ASIO driver, or you can use ASIO4ALL.
WASAPI is the Microsoft solution to get lower latency. It has 2 modes:
- WASAPI Shared mode, that shares the audio in/output with other applications, restricting the setting of Sample frequency and data bits to be determined by the Systems Sound Playback/Recording Advanced Properties ->
- WASAPI Exclusive mode, that handles an in/output exclusively giving LUCI the ability to determine sample frequency and data bits.
When WASAPI is selected you can set the hardware’s desired latency or leave it to it’s default. At Shared mode you also see the Samples frequency set at the device properties.
Known problems on Windows 10 ,and newer MAC os:
If on Mac the audio input is not working or on Windows 10 you get the message:
Can not start audio I/O.
Please check the sample-rate or connections.
and you are sure that the Audio device Input and Output are connected and in working order than chances are that the Systems Microphone privacy settings are not properly set.
On Windows 10: Type “Microphone privacy settings” in the Search bar of your System and set the “Allow Desktop apps to access your microphone” to on.
On MacOs: Navigate to Security and Privacy in the System Preferences drop-down menu. Next, open the Privacy tab, where you will find a list of different features and services that can be accessed by the apps you have installed. Choose the Mic and select the LUCI app to grant access to the Microphone.
