Is it possible to gain more control over recording quality? AFAIK Opus supports much worse quality than the "worst" setting. I am actually looking for something exacly like this, but I need to support as many streams as possible and being able to fiddle around with sample rate and bit rate would be preferable over some predefined quality levels.
