The article's author, Chris "Monty" Montgomery, is one of the authors of Ogg Vorbis [1] and Opus [2].

It puzzles me that many people don't yet know about Opus. Let me quote the FAQ [3]:

"Does Opus make all those other lossy codecs obsolete?

Yes.

From a technical point of view (loss, delay, bitrates, ...) Opus renders Speex obsolete and should also replace Vorbis and the common proprietary codecs too (e.g. AAC, MP3, ...)."

I use Opus for music playback for all my archived music. The reason it's not more widespread was opposition of the likes of Apple to free codecs. Today they are losing this, and Opus is making its way even to Apple's systems.

    Is there a particular reason you don't opt for lossless formats (e.g. FLAC) for your music archive? I imagine the only constraint would be space, though storage gets cheaper by the year.

      I use FLAC for storage, and Opus for playback. I.e. in essence I use both. The benefit of lossless is ability to re-encode later to any new codec (Opus-next?) if it will be useful. For playback, transparent Opus is good since it takes less space.

      I.e. in practice - in my main archive I use FLAC. On some portable players and etc. I use Opus encoded from that FLAC.

      That's why I always try to buy music in FLAC when possible and stores like Bandcamp are great for it.

I love opus just as much as I loved musepack and vorbis, the one thing all of them lack to one degree or another is support and hardware acceleration. If I throw an opus file on my Android 8.1 phone, it has no idea what to do with it unless I manually open it with vlc or foobar. For the regular user the support needs to be seamless, otherwise they are not going to bother.

I thought for a moment that Spotify uses Opus, but it turns out that they use Vorbis. Wonder why a switch isn't on their roadmap.
