Capturing audio with shared event driven mode
This example shows that the capturing audio with shared event driven mode.
Prerequisites
- Go 1.13 or later
Build
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'.
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
Stability of the event driven mode is much lower than the timer driven mode. Because we cannot control the scheduling of goroutines, when the goroutine which observing audio ready event was stopped, stutterring occurs.

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.
