Allows recording from eCapture(recording) and eRender (playback) devices Audio capture UDf in autoit allows you to capture 'what you hear' to a wav file using a loopback Event driven capturing allows your GUI to stay responsive and doesn't use a lot of your cpu Loosely based on https://github.com/mvaneerde/blog/blob/master/loopback-capture/loopback-capture/loopback-capture.cpp Wav saving inspired by Eukalyptus https://www.autoitscript.com/forum/topic/164700-directsound-udf/ UDF WasApi_Capture.au3 Example Edit: added IMMEndpoint.GetDataFlow to allow the loopback flag to be removed from eCapture Devices so you can record eRender and eCapture Devices now added _WASAPI_Stream_Dataflow to get device direction eRender (playback), eCapture (recording), eAll Cleaned up error handling in the UDF should be more comprehensive (At least CLEANER!) Fixed Windows 10 event mode Proper handling of Wave Extensible Format, Cleaned up example code a bit FIxed Error with Non Wave Extensible Formats and added paused code from Argumentum Cleaned up code added the ability to only capture every n number of frames 1Ms in the example Capture_Example.au3 WasApi_capture.au3
