None of the audio samples play for me (In neither Chrome nor Edge... Other sites play just fine.)

Makes it very hard to evaluate claims of codec quality, which seems like the primary purpose of the blog post. :(

Seriously impressive and game-changing results, especially when you take Wavenet into account. I'm curious to see how Wavenet would perform w/Opus.

Works for me on my iPad.

On a related note, I wish more (any!) podcasts were distributed in opus.

Make sure you get to the end and listen to the WaveNet samples, amazing stuff.

All the +2k podcasts hosted on Podigee (a podcast hosting company mainly known in German-speaking countries) are distributed in opus. But it is, and probably will always be, a rather niche distribution format. AAC had its moment, but MP3 is alive and kicking. Even Apple acknowledges its importance by adding support for chapter markers in iOS12.

As far as I know, enough podcast apps require MP3 (and not even VBR!) that you have to use MP3, and you can't have multiple s, so how would you do this? A separate RSS feed for Opus, linked only on the website and not submitted to aggregators?

Having grown accustom to MP3 artifacts, it's strange to hear artifacts that are natural, but just aren't quite right. More specifically, in the male voice sample: "sold about seventy-seven", I received it as "sold about sethenty-seven".

There are a lot of playback issues - VBR MP3 and older OS releases of both iOS and Android, never mind the car players and similar all contribute to the problem.

The post-show of this podcast talks about these and other issues in detail - Marco is on both sides of the issue as a podcast producer and podcast app developer: http://atp.fm/episodes/182
