if it works well with RadioBoss and is accessible with screen readers, that's a great find.
It does not work well with screen readers if you use the default interface of the plugin, but it is definitely interesting.
It works well if you use it with the accessible interfaces that rap vst's such as the combination reaper and osara provides, as well as those found in audacity and goldwave.
In terms of the plugins performance... I feel that master_me delivers a smooth sound by default and includes a useful phase correction module for signals that are out of phase. That said, pushing the plugin to apply aggressive compression or limiting, which you may need for a radio stream, results in an overly harsh, edgy signal. Additionally, the built-in leveler operates quite slowly, which can be problematic. Sudden transitions from quiet to loud audio often cause the brick wall limiter to temporarily deal with peaks exceeding 0 dB until the leveler adjusts and takes effect.
Despite these limitations, master_me would be great for gently leveling audio, particularly for formats like talk shows or easy-listening content, where subtle adjustments would give the result a little polish.
Although this plugin is inaccessible by default, as are plugins such as JB Broadcast, and TB Broadcast, I'm still going to recommend it in the specific use cases mentioned above. Thank you for point it out.
