ASIO 驱动程序仅适用于 Windows，与 macOS 无关。FL Studio 安装包含 FL Studio ASIO，而此处提到的第三方 ASIO4ALL 驱动程序必须单独下载并安装。ASIO 有两个优势：

速度：ASIO 驱动程序（通常）比标准 Windows（"主声音驱动程序"或 WDM 驱动程序）具有更低的 CPU 开销和更低的缓冲区设置。如果您的音频设备自带 ASIO 驱动程序，我们建议您使用该驱动程序。
多音频设备：ASIO4ALL 和 FL Studio ASIO 独有的功能是，您可以从不同的音频设备中选择输入和输出，这是标准 ASIO 驱动程序无法实现的。此功能允许您同时使用 USB 麦克风输入和常规音频设备输出（请参阅下文第 7 点）。
注意：ASIO4ALL 是一款通用的 ASIO 驱动程序，适用于大多数音频设备，您的体验可能会有所不同，包括长时间的静音和令人费解的体验。如果 ASIO4ALL 没有发出任何声音，我们建议您完成以下所有步骤，包括"故障排除"部分，或者使用 FL Studio ASIO 驱动程序。

使用 ASIO4ALL 高级设置
本部分介绍如何使用 ASIO4ALL 设置。要观看视频教程，请点击此处。

按下电脑键盘上的 F10 键，然后点击扬声器图标选择"音频设置"。或者，从"选项"菜单中选择"音频设置"。
选择 ASIO4ALL v2，如下所示。
ASIO4ALL 选项

要打开 ASIO4ALL 设置 - 点击"显示 ASIO 面板"（如上所示）。下图显示了 ASIO4ALL 处于"简单模式"。右下角的"扳手"按钮可在"简单"和"高级"模式之间切换。
ASIO4ALL 基本模式

ASIO 缓冲区大小 - 如上所示，ASIO4ALL 窗口允许您调整 ASIO 缓冲区大小（缓冲区长度）设置，以微调缓冲区欠载问题。您可以调整每个选定设备的缓冲区长度（在本例中，选定的是 Creative SB X-Fi，以深蓝色突出显示）。建议将所有计划使用的设备设置为相同的缓冲区大小。点击设备名称使其高亮显示，然后更改缓冲区大小滑块。缓冲区大小以样本为单位显示，要将样本转换为毫秒 (ms)，请将缓冲区长度（以样本为单位）除以 44.1（如果您的音频设备使用 44100 Hz）或 48（如果您的音频设备使用 48,000 Hz）。在本例中，音频设备设置为 44100 Hz，因此 448 个样本的缓冲区长度 = 10 毫秒（约）。
WDM 设备列表 - 屏幕截图还显示了 WDM 设备列表中的 2 个设备（Creative SB X-Fi 和 Plantronics 耳机）。您列表中显示的设备可能有所不同，这些设备已正确安装音频设备驱动程序并在 Windows 操作系统中注册。如果您的声音在 Windows 下正常工作，则应该至少列出一个设备（名称中带有 Realtek 或 AC97 的设备通常用于基于主板的音频设备）。如果此列表中未显示任何内容，请重新安装 PC 的音频设备驱动程序，然后重新启动并再次查看此处。
高级设置 - 确保您处于如下所示的高级模式。点击扳手（右下角）可在"简单"和"高级"模式之间切换。
ASIO4ALL 高级模式

活动设备 - FL Studio 只能使用活动设备（及其活动输入/输出），即显示在混音器输入和输出菜单中的设备。这是将 USB 麦克风与您的音频设备配合使用所必需的步骤。要激活设备，请点击设备名称前面的按钮，蓝色按钮和箭头将亮起，表示设备已激活。您还必须确保设备的输入 (In:) 和输出 (Out:) 也已激活。点击设备前面的任意 [+] 方块以展开输入和输出列表，然后点击激活按钮。注意：在最高级别激活设备并不一定意味着其输入和输出已激活。例如，在上面的屏幕截图中，Plantronics 耳机输出未激活，因此在 FL Studio 中不可用。
延迟补偿输入/输出 - 滑块。保留这些默认设置。ASIO4ALL 驱动程序会向 FL Studio 报告它添加到音频流的延迟，程序会在适当的情况下将此考虑在内。但是，如果您已经使用环回电缆测量了音频设备的输入/输出延迟，并且知道自己在做什么，那么请根据测量结果设置"延迟补偿"滑块。
使用硬件缓冲区 - 可以减少缓冲区欠载。此选项是否有用取决于音频设备和驱动程序的设计。
始终以 44.1 kHz <-> 48 kHz 的频率重新采样 - 此选项可修复 SigmaTel C-Major 音频设备上的无声问题。如果您的音频设备设置中的其他所有设置都正常，但您没有听到任何声音，可以尝试此选项。
强制 WDM 驱动程序为 16 位 - 此选项可修复 SoundMax 数字音频设备上的无声问题。如果所有

ASIO Drivers are only relevant to Windows, not macOS. The FL Studio installation includes FL Studio ASIO, while the 3rd party ASIO4ALL Driver mentioned here must be dowloaded and installed separately. There are two advantages of ASIO:

Speed: ASIO drivers (in general) allow lower CPU overhead and lower buffer settings than the standard Windows ('Primary Sound Driver', WDM Driver). If your audio device has a native ASIO driver then we recommend you use that.
Multiple audio devices: Unique to ASIO4ALL & FL Studio ASIO, you can select inputs and outputs from separate audio-devices, something that is not possible with standard ASIO drivers. This feature allows you to use a USB microphone input and your regular audio device output at the same time (see point 7 below).
NOTE: ASIO4ALL is a generic ASIO driver that works with most audio devices, your experience may be different, including long periods of silence and head-scratching. If ASIO4ALL doesn't produce any sound we recommend that you work through all the steps below including the Troubleshooting section OR use the FL Studio ASIO driver.

Using the ASIO4ALL Advanced Settings
This section explains how to use the ASIO4ALL settings. To see a video tutorial Click here.

Press F10 on your PC keyboard and select the Audio settings by clicking on the speaker icon. Alternatively choose Audio settings from the Options Menu.
Select ASIO4ALL v2 as shown below.
ASIO4ALL options

To open the ASIO4ALL settings - Click on the 'Show ASIO panel' (shown above). The screenshot below shows ASIO4ALL in 'simple mode'. The 'spanner' button, on the lower-right, changes between 'simple' and 'advanced' modes.
ASIO4ALL Basic Mode

ASIO Buffer Size - As shown above, the ASIO4ALL window allows you to adjust the ASIO Buffer Size (Buffer length) settings to fine-tune Buffer underrun issues. You can adjust the buffer length for each selected device (in this case the Creative SB X-Fi is selected, highlighted dark-blue). It is a good idea to set all devices you plan to use to the same Buffer Size. Select each device by clicking on the name so it becomes highlighted and then change the Buffer Size slider. The Buffer Size is displayed in samples, to convert from samples to milliseconds (ms) divide the Buffer length in samples by 44.1 (if your audio device is using 44100 Hz) or 48 (if it is at 48,000 Hz). In this case, the audio device is set to 44100 Hz so the Buffer length of 448 samples = 10 ms (approximately).
WDM Device List - The screenshot also shows 2 devices in the WDM Device List (Creative SB X-Fi and Plantronics Headset). The devices that appear in your list will probably be different and are those audio devices that have audio device drivers correctly installed and registered with the Windows operating system. If your sound is working correctly under Windows, there should be at least one device listed (something with Realtek or AC97 in the title are common for motherboard-based audio devices). If nothing is showing in this list, re-install the audio device drivers for your PC, reboot and look here again.
Advanced settings - Make sure you are in Advanced mode as shown below. Click the Spanner (lower-right) to change between 'Simple' and 'Advanced' modes.
ASIO4ALL Advanced Mode

Active devices - Only active devices (and their active Inputs/Outputs) can be used by FL Studio, i.e show in the Mixer IN and OUT menus. This is the step that is required to use a USB microphone with your audio device. To activate a device click the button in front of the device name, the blue button & arrow will light to indicate the device is active. You must also ensure that the device's Inputs (In:) and Outputs (Out:) are also activated. Click on any [+] squares in front of the device to expand the list of Inputs and Outputs and click on the activate buttons. NOTE: activating a device at the highest level does not necessarily mean its inputs and outputs are activated. For example, in the screenshot above the Plantronics Headset Output is not activated and so won't be available in FL Studio.
Latency compensation In/Out - sliders. Leave these at the default settings. The ASIO4ALL driver reports to FL Studio the latency it adds to the audio stream, and this is taken into account by the program where appropriate. However, if you have measured the input/output latency of your audio device using a loop-back cable, and know what you are doing, then set the 'Latency compensation' sliders according to your measured results.
Use hardware Buffer - Can reduce Buffer underruns. Whether or not it helps will depend on the design of your audio device's design and drivers.
Always resample 44.1 kHz <-> 48 kHz - This option fixes a no sound issue on SigmaTel C-Major Audio devices. If everything else seems to be correct on your audio device settings and you are not hearing anything you can give this option a try.
Force WDM Driver to 16-Bit - This option fixes a no sound issue on SoundMax Digital Audio devices. If everything
