I remember when this addon used to work - in the sense of converting videos to mp3s, it wasn't consistent in converting vids to 320Kbps mp3 files. Even with the ticker set to 320Kbps conversion, this addon would produce 128Kbps! So, no consistencies & reliability. Sometimes on a lucky day, you got 320Kbps, and other times, 128Kbps (with quality selection set at 320Kbps) - defeating the purpose of "Quality Selections to 320Kbps", because when I tried the same vid - that this addon produced 128Kbps in other online, regular converters - I got 320Kbps (except without audio adjustments this addon had)!
Then there was the issue of one moment or week or month - it works. Then the next week or month - it does not work. So I basically had to check all supposedly 320 Kbps mp3 files, from this addon, using the Speks tools, and to my surprise, lots of them were 128Kbps. Last time of using this addon was around November 2022 to around January 2023 or so. Never seen anything like this addon. Nothing gets fixed but I'm sure the developer wants 5 stars. Keep dreaming! 1 star, buddy.
