Windows comes with a Virtual Loopback Network Adapter, why not an Audio one? Does anyone here have experience with writing Audio Drivers in Windows? It can be optimized for minimum overhead and since it's a driver it will run continuously in the background. It could receive all audio streams, process them and transfer them to the actual Sound Card Driver to output. It should be possible to create a standalone Virtual Loopback Audio Driver without attaching it to hardware. Media Player -> Reaper ReaRoute -> Reaper VST DSPs -> Sound Card -> Amplifier

It has a very good virtual audio driver called ReaRoute and a VST host simplifying this type of work. Another popular solution is the DAW Reaper. The hardware of SoundCard1 is not necessary, the sound stream is usually routed in the driver and never reaches the card itself. Media Player -> SoundCard1 -> DSP software -> SoundCard2 -> Amplifier Then the software sends the processed sound to SoundCard2 which outputs it to the amplifiers.

Usually that is done in a VST host that runs several plug-ins. A software that runs continuously on the PC picks up the stream from SoundCard1 and does the necessary processing. SoundCard1 routes the stream internally and makes it available at its inputs. All sound applications output to SoundCard1. The most popular solution for a PC crossover seems to be using 2 sound cards.
