In the past I've chosen I've often kept AC3 audio tracks thinking that their substantially higher bitrates made them better than the AAC tracks I compared them to. As I've since learned that AAC can be comparable to AC3 at a substantially lower bitrate, to have a means of comparing the two codecs, what would the AAC-equivalent bitrates be for 224kbps and 640kbps AC3?
In the case of 1337x.to, the megathread lists 1377x.to as the fake replica of it. In terms of quality, 1337x.to is one of the best public torrent indexers.
While I personally prefer not to use YTS releases due to their low quality, and can't seem to find a legitimate YTS link that yts.mx would be the replica of, as long as you're downloading via Prowlarr rather than going to the website itself, the only risk is the trustworthiness of the releases, rather than the possibility of ads or otherwise unwanted links on the website itself.
