To the dev: the tuner gives me an incredibly high error window with the following message. It doesn't prompt to access the mic (I think that's related). Ubuntu/KDE/Firefox:
Thank you for providing error feedback. We will work hard to address it. Currently, the model-related data is relatively large, which may be related to network speed.
I got the same error on Ubuntu/GNOME/Firefox. On Chrome, I don't get an error and I'm correctly prompted for microphone access, but if I grant permission, it does not seem to pick anything up (I've used my mic successfully with other web apps).
