Deceptively Difficult Windows Audio Routing Problem

How is possible to insert VST Audio Effects, running in an ASIO Host, into the Windows Audio Stream?

Goal : talk with a processed voice when using Skype. Not interested in the various 'voice changer apps out there, but intend to use pro vst effects for things like compression and noise reduction.

Steps :

  1. Speak into a headset, and pass the audio to Ableton Live (ASIO VST Host)
    • No Problem – Have a Bluetooth headset windows audio device. Can pass its input – my voice – into my EMU 1212M "PatchMix" mixer via the 'Listen to this device WIndows "Mic Properties" dialog. From there I can mute the direct signal and pass it into Ableton via ASIO.

  2. Process my voice in using a VST chain in Live, routing the output back to windows where it can be used as a device in Skype.

    • This is the tricky part. I can pass the processed audio back out to my EMU Mixer, but the resulting stream will not appear within Skype since it is an OUT stream; not IN.

So, the remaining problem is to find or write a piece of software something akin to a virtual webcam, but for audio.

Does anyone know of such a driver/device which can make an output of one windows audio device appear as an input of another virtual device?

Best Answer

You might have some luck with Virtual Audio Cable by recording the mic directly into Live, routing Live's audio to VAC. Then just tell skype to use VAC as its input device.
