Questions: Equalizer APO support, multi-channel, loopback, and device capabilities

[DevonTM]

Hi, thank you for this project! I’m interested in the current functionality of the Virtual Audio Driver and would like clarification on a few advanced features:

1. Device Type and Capabilities

   • Is the virtual audio device currently implemented as a true WaveRT device, or is it only a dummy/fake device?
   • Does it handle full audio routing and processing (like a real device), or is there some limitation?

2. Equalizer APO Compatibility

   • Does the virtual device support Equalizer APO? For example, is it visible/selectable as a target device for system-wide equalization in Equalizer APO?
   • Are there specific INF settings or steps needed to make the virtual device compatible with Equalizer APO?

3. Multi-Channel Audio Support

   • Does the driver currently support more than 2 channels (for example, 5.1 or 7.1 surround configuration), or is it limited to stereo?

4. WASAPI Loopback Support

   • Can the virtual speaker device be used for WASAPI loopback capture (i.e., is it visible as a loopback-capable endpoint for recording system audio)?
   • Are there current limitations or is there a roadmap for this feature?

5. Audio Processing Objects (APOs)

   • Can the virtual device host custom or third-party APOs aside from Equalizer APO (such as system effect DLLs registered via INF)?

Any clarification on these points or pointers to documentation would be greatly appreciated!

Thanks!
