DS WASAPI ASIO 路由器混音器是音频输入到音频输出路由器/混音器，支持 Direct Sound、WASAPI 和 ASIO 模式。任何类型和数量的音频输入都可以通过矩阵混合、VST DSP 插件支持、11 段均衡器和录音选项路由到任何类型的音频输出。 ASIO 输出混音器可选多线程，以通过 DSP 实现高分辨率 96/192KHz 输出的最低延迟。均衡器、矩阵混音和 VST DSP 有一个预设系统来存储和调用设置。
使用 DS WASAPI ASIO 路由器混音器的基本步骤：
在窗口的中上部选择一个输出设备。在右侧设置所需的格式，然后单击“启用”开关。 ASIO 通道对继承根设备的参数，因此如果需要，请先设置根参数。
在窗口的左侧选择一个输入设备。在右侧（整个窗口的中心）选择输入所需的格式，然后单击“启用”开关。选定的输入设备将开始在先前选定的输出设备上播放。输入设备始终通过最后选择的输出设备启用。可以为 1 个输出设备启用多个输入设备，但输入设备仅支持 1 个输出，但在输入设备选项面板中，可以（在底部）指定另一个“监视器”输出设备，这需要之前启用，这也将播放选定的输入设备。
要访问底部的 3 个 FX，请从列表中选择一个输入或输出设备。最后选择的输入或输出设备将受到影响。下部面板的组框标题显示当前选定设备的名称（输入或输出）。
例如，要将均衡器应用于设备，请设置 EQ 轨迹条并单击“启用”。当然，参数也可以随时更改。
ASIO 通道对从根设备接收音频数据，因此在根设备上设置任何效果，如音量或 EQ、VST DSP 都会影响所有通道对。请注意，大多数 VST DSP 插件仅支持立体声，因此 1/2 以外的通道可能不受影响或静音，在这种情况下，请在通道对上设置 VST DSP。
提示：
输入和输出通道/设备“格式”设置可能无效。 WASAPI 和根 ASIO 设备的通道数总是如此。输入和输出 ASIO 设备将始终具有支持的最大通道数，ASIO 对通道将始终为立体声。启用设备/通道后，实际格式显示在设置选项下方。要设置 WASAPI 设备的格式，请使用 Windows 音频设备控制面板。
ASIO：如果输出正在跳过，则增加 ASIO 设备的缓冲区大小。可以通过启用设备然后右键单击设备名称并选择“ASIO 控制面板…”来访问 ASIO 设备的配置窗口。更改设置后可能需要重新启动 DS WASAPI ASIO Router Mixer。如果您的计算机的 CPU 具有省电功能（CPU 在空闲时被节流），如果输出仍在跳过，请将 Windows 控制面板中的 CPU 省电选项调整为 50% 或更高。用鼠标中键单击输入/输出峰值编号可以节省一点 CPU 时间。这将禁用峰值计算过程。最快的 CPU（截至 2019 年 4 月）是适用于该应用程序的 Intel Core i9-9900K @ 3.60GHz。对于 ASIO 输出，如果在设置中启用了多线程处理，则具有更多内核的 CPU 更佳，此功能是实验性的，只有在有很多 ASIO 通道时才有优势，通道上有很多 VST DSP 等效果.
VST DSP：双击插件名称，弹出插件配置窗口。要重置它的设置，请右键单击插件的名称，然后从菜单中选择“将插件重置为默认值（禁用）”。
在处理输入和输出通道/设备时，建议始终以 32 位浮点样本格式模式工作。录音可以设置为任何需要的格式，样本数据将转换为设置的格式进行录音。
ASIO 根设备录制：可以录制 ASIO 根设备，并选择仅录制启用的立体声通道对。对于“通道”选择“活动对”，将仅记录活动通道对。例如，如果启用 ASIO 对 1/2 和 5/6，则录制将包含 4 个通道：1/2 和 5/6。请注意，仅 WAV PCM、Opus、FLAC 和 Ogg Vorbis 格式支持多声道录音。
DS WASAPI ASIO Router Mixer is an audio input to audio output router/mixer with support of Direct Sound, WASAPI and ASIO modes. Any type and number of audio inputs can be routed to any type of audio output with matrix mixing, VST DSP plugin support, 11 band equalizer and recording option. ASIO output mixer is optionally multi-threaded to achieve lowest possible latency for high resolution 96/192KHz output with DSPs as well. Equalizer, matrix mixing and VST DSPs have a preset system to store and recall settings.
Basic steps for using DS WASAPI ASIO Router Mixer:
In the upper-center part of the window select an output device. To the right set the desired format and click the ‘Enable’ switch. ASIO channel pairs inherit the root device’s parameters so set the root parameters first if needed for the pairs.
In the left part of the window select an input device. To the right (center of the entire window) select the input’s desired format and click the ‘Enable’ switch. The selected input device will start playing on the previously selected output device. The input device is always enabled through the last selected output device. It’s possible to enable multiple input devices for 1 output device, but only 1 output is supported for an input device, but in the input device options panel it’s possible (at the bottom) to specify another ‘monitor’ output device, that needs to be enabled previously, that will play the selected input device too.
To access the 3 FXes on the bottom select an input or output device from the list. The last selected input or output device will be affected. The lower panel’s groupbox caption displays the currently selected device’s name (input ot output).
For example to apply an equalizer to the device, set the EQ track bars and click on ‘Enable’. Of course the parameters can be changed on the fly too.
ASIO channel pairs receive audio data from the root device, so setting any effect, like volume or EQ, VST DSP, on the root device will affect all the channel pairs. Note that most VST DSP plugins support only stereo, so other then 1/2 channel might be unaffected or muted, in this case set the VST DSPs on the channel pairs.
Hints:
Input and output channel/device ‘format’ settings may have no effect. This is always so with WASAPI and with root ASIO devices’ channel count. Input and output ASIO devices will always have the maximum number of channels supported, ASIO pair channels will be always stereo. After enabling the device/channel the actual format is displayed below the set option. To set WASAPI devices’ formats, please use the Windows audio devices control panel.
ASIO: if the output is skipping increase the ASIO device’s buffer size. It’s possible to access the ASIO device’s configuration window by enabling the device then right mouse clicking on the device name and selecting ‘ASIO Control Panel…’. Restart of DS WASAPI ASIO Router Mixer might be needed after changing the setting. If your computer’s CPU has power saving functionality (the CPU is throtled when idle) adjust the CPU power saving option in Windows control panel to 50% or higher if the output is still skipping. A little CPU time can be saved with middle mouse button clicking on the input/output peak value number. This disables the peak calculation process. The fastest CPU (as of April 2019) is the Intel Core i9-9900K @ 3.60GHz for the application. For ASIO output, if multi-threaded processing is enabled in settings, a CPU with more cores is more optimal, this functionality is experimental and only has advantage if there are a lot of ASIO channels with a lot of effects like VST DSPs on the channels.
VST DSP: to bring up the plugin’s configuration window double click on the plugin’s name. To reset it’s settings right mouse click on the plugin’s name and from the menu select ‘Reset Plugin To Defaults (disable)’.
It is advised to always work in 32 bit float sample format mode when dealing with input and output channels/devices. Recording may be set to any desired format, the sample data will be converted to the set format for recording.
ASIO root device recording: It’s possible to record ASIO root devices with option to only record the enabled stereo channel pairs. For ‘channels’ select ‘Active pairs’, only active channels pair will be recorded. For example if ASIO pair 1/2 and 5/6 is enabled the recording will contain 4 channels: 1/2 and 5/6. Note that multi-channel recording is only supported by WAV PCM, Opus, FLAC and Ogg Vorbis format.
