I used to dabble in Internet streaming. I used JB Broadcast in my DSP chain many years ago. I agree that it does work decently enough to get the "commercial broadcast sound" without a significant learning curve.
I have a Stereo Tool license these days. I use ST more for listening, usually meaning *reverting* much of the "commercial broadcast sound" with declipping, dynamics, etc. ;)
BTW, if looking for hardware solutions, the various older Alesis micro and nano processors used to be rather reasonable on eBay and used audio gear sites. I have not used them in a long time, but I hang onto have my old Alesis compressor, enhancer, noise gate, etc. since hey do not take up much storage space.
