Rendering with exclusive event driven mode
This example shows that the rendering audio with exclusive event driven mode.
Prerequisites
- Go 1.8.1 or later
go-ole(https://github.com/go-ole/go-ole)
Download
You can download the executable from Releases page.
Build
go build
That's it. Then you'll get RenderExclusiveEventDriven.exe. Note that your platform is not Windows, you need set the environment variable GOOS='windows' before building the executable.
Usage
./RenderExclusiveEventDriven -i music.wav
Please specify the WAVE audio file with -i or --input flag.
Note
Whether the wAV file can play or not is up to hardware settings. You need specify the WAV file which is encoded as same as output settings.
For example, when the output is configured to comibination of 96 kHz and 24 bit, you can only play WAV files which are encoded with 96 kHz and 24 bit.
Known issues
Some audio interfaces fails playback in exclusive event driven mode. I use Steinberg UR22 as an external audio interface, and the interface can play correctly in timer driven mode, but it makes glitch in event driven mode.
I don't know why but if you want to use exclusive audio rendering, you should use timer driven mode for now.

The Windows Core Audio API was introduced Windows vista, so that the later than that version of Windows could run this example. However, I'm not sure because I've just tested this example on Windows 10 version 1607 at the moment. Operation verification including bug report are welcome.
