1 声卡设置
⮮依次选择“OPTIONS”，“Audio settings”，“Audio”。如图所示。
⮮因为本机没有安装独立的声卡，这里选择了默认的“FL Studio ASIO”。
如果没有ASIO devices这个选项，选择“主声音驱动程序”也是可以的。
⮮一些不太详细的说明如下：
ASIO Audio Interface
The proprietary ASIO interface standard is essential on Windows for low latency recording and playback. It is also usually the best way of making Multi-channel recordings on Windows.
Latencies on Windows, Linux and Mac
ASIO is a proprietary audio interface standard in use on Windows which bypasses the operating system's mixing kernel, so providing lowest latency direct communication between computer audio software and hardware.
- ASIO supports 24-bit sampling which is only otherwise available under Windows WASAPI or WDM-KS (Windows Driver Model Kernel Streaming). 24-bit sampling allows greater dynamic range, lower theoretical noise floor and greater resolution at lower audible volumes.
- An unmixed ASIO output is "bit identical" to the original source.
- Multiple physical input and output channels of the hardware are accessed over one single device.
On Linux, the standard ALSA audio API typically provides lower latencies than Windows under MME or Windows DirectSound. However, many Linux distributions now use PulseAudio by default for audio routing and mixing. PulseAudio sits between the sound source and the Linux kernel and thus has somewhat higher latency than direct use of ALSA. For lowest latencies, you can use the JACK API that provides both low latency audio communication and audio routing between applications. Current Audacity supports JACK fairly well, but with some limitations.
On Mac, Core Audio is the standard API and is fully supported by Audacity. Core Audio also has lower latencies than Windows under MME and Windows DirectSound but Jack OS X can be used for lowest latency.
简而言之一句话：优先选择ASIO！。除非没得选，才选DirectSound Device。
而ASIO中，优先选择你声卡对应的ASIO，或者FL Studio ASIO。
