What you wouldn't be able to do though is tap into an ASIO stream - so by using ASIO4ALL you're probably going along the right lines. Good luck with that - it can potentially be a bit of a nightmare to get that to work - but it should, unless I'm mistaken. Wave sound events played in Windows (up to ) and MIDI I/O use MME. But if you're using ASIO4ALL it doesn't have to! All you need to do is to configure VAC so that it picks up the streams you want to interconnect. Contents.Multimedia Extensions (MME) The MME API or the Windows Multimedia API (also known as WinMM) was the first universal and standardized Windows audio API. So nothing else is having to handle ASIO - simply because it can't. For why this is necessary, you have also to bear in mind that Windows is trying to get in the way of everything you do - calling it an 'operating' system is a bit of a joke. And that's what it does for Audition - converts its inherently ASIO-based I/O so that it runs with Windows-based drivers.Īs far as I'm aware, VAC can't tap into a real ASIO stream, as the purpose of this is to cut out most of the operating system between the ASIO output of your software, and your audio device - which is how it decreases the latency. During playback using DirectSound or MME via WDM-Audio an error situations could occur when the driver was not supplied with enough playback data by the WDM.

You have to bear in mind that ASIO4ALL isn't an ASIO 'driver' as such - it's a means of converting ASIO-based software so that it will run with native windows audio - MME and WDM.
