Good news on the read-aloud! I have figured out what muddied up the sound in my last audio test (pretty obvious - it was hot as hell, so I had a fan running) and done a few audio tests with fans off on different mics. Picked which headset I want to use. Next step, when I get to it, is to play with Twitch a bit to figure out a good setup.
Also... sigh... Twitch has (misogynistic!) adult content moderation bullshit instead of giving options for CWs or, hell, selective muting*, so there are certain scenes I'm going to just have to figure out handling separately.
...the torture scenes, meanwhile, are allowed to stay in because the book doesn't "exclusively focus" on them.
