Re: Vorbis better than opus?

I can hear frequencies above 20KHz, confirmed by ABX, with and without 20KHz lowpass. This guy is smoking some good shit, lol. Anyway, nobody is using Vorbis anymore. It is dead format. If you want compatiblity and good all-around format stick with MP3. Use latest LAME encoder and use V2 preset. You will get ~192 kbit/s files that work everywhere and sound great. If your equipment has been made in the past ~15 years you can use AAC-LC. Recommended encoder is Apple (qaac). Ideal bitrate is around 144-160 kbit/s. Third "relevant" format acording to HydrogenAudio is Opus. This is totally false in real life. Even today, many programs have problems with playing Opus files. It is really only useful for VoIP applications. I can guarantee you that every single person on HA that is using Opus is very familiar with compatibility problem but they also have lossless archive so they can encode to any format that they want. Main point of lossy files is transparency at smallest bitrate. Lossy codecs achieve this at 192 kbit/s. Everything about 192 kbit/s kills the point of lossy files. I'd rather use 192kbit/s Musepack and with Android being so popular compatibility not a issue these days, Since MPC seems more robust on some Noise/transient samples that Opus groans on. But overall Vorbis is worse than AAC/MP3 by long shot not even transparent on most samples at 256kbps while AAC/MP3 are to be blunt.
