Capturing with shared event driven mode
This example shows that the capturing audio with shared event driven mode.
Prerequisites
Build the executable
go build
That's it. Then you'll get CaptureSharedEventDriven.exe. Note that your platform is not Windows, you need set the environment variable GOOS='windows' before building the executable.
Usage
./CaptureSharedEventDriven -o music.wav -d 10
Please specify the flag -o or --output for saving audio file. The -d or --duration is optional and it indicates recording duration in second. If the recording duration was not specified, it keeps recording until receiving interruption by Ctrl-C.
Note
This example captures the audio as 44100 Hz / 16 bit wave format audio. The capturing step will be failed when the sample rate and bit depth of system default capturing device is not set as that value.
To avoid this error, please set the system default settings for shared mode recording.
- Open control panel and select sound.
- Select recording tab and open property of the main recording device.
- Select the advanced tab, set the default sample rate and bit depth as 44100 Hz / 16 bit.
- Apply changes.

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.
