Any way to increase audio bitrate/channels?

[ThreeDeeJay]

Even though ShadowPlay vanilla allows adjusting video bitrate, audio bitrate seems to max out at a measly 196kbps.

So I was wondering if this tool could force a higher bitrate or better yet, record lossless (WAV/PCM) audio, perhaps using WASAPI loopback which should even allow recording surround sound from games/apps.
