@lamb @wyatt Fortunately, Opus is available out of the box pretty much everywhere nowadays except in Safari prior to macOS 15.4. This was helped by Opus being a collaboration between vendors (Microsoft and Xiph), not just something coming out of Xiph's or Google's cathedral. I do see on https://caniuse.com/opus that Safari supported Opus in Apple's CAF container before Xiph's Ogg container; might Apple have identified some obscure patent encumbering Ogg?
And you're right that Opus soundly beats MP3 in the "bitrate needed to stop being terrible" measure.

Apple added OPUS and FLAC support to AudioToolbox a while ago (iOS 17), but for some reason AVPlayer does not support it.
While I appreciate it, it feels very half ass. It’s like they want to use it internally (iMessage Audio Messages are using OPUS), but they don't want to incentivize a larger adoption of it.
So if you want to use OPUS to play audio, you need to build the whole HTTP Streaming mechanic on your own.

Das #Xiph Directory ist wohl gerade nach Bad Gateway umgezogen.
Hat jemand einen Status? Wann das wieder läuft?

Never mind that I saved this to the wrong place.
I like #PhonographPlus because I can edit the tags. There are so many tag fields! I decided for full albums, some are worth writing the tracklist in a [custom] field. Perhaps there is a better choice, I'm not sure yet but, this will do.

He documented the process on his blog, joining the tracks as a single stream and compressing it down to 6.7 kbps until it fit a single 1.44 Mio 3½-inch disk.
An album on a floppy.

@liaizon Maybe @alcinnz or someone writing about #xiph?

... (#acxi con'd)
A few things acxi is NOT:
* a cd ripping tool. Check out #abcde, it does a good job for cli ripping tool.
* a media player
* a strong supporter of #nonfree #audio #codecs like #AAC or #MP3. It offers adequate, basic support, and that is it.The focus is always going to be on mainly #xiph.org #vorbis things like #flac, #opus, #ogg (to a lesser extent, since vorbis has moved all dev efforts to opus).
acxi will support the others enough to let you translate them to free codecs.
-
And #acxi is now in #slackbuilds!
https://slackbuilds.org/repository/15.0/audio/acxi/
and that was picked up quite rapidly by #repology.
https://repology.org/project/acxi/versions
I do not expect this to make any real difference, beyond maybe a few people discovering that acxi does something they find useful that might not otherwise have discovered that.
Here's to Free Audio, something not to be taken lightly or for granted, for without the tireless efforts of groups like #xiph.org and others, we would be in proprietary codec hell.

This video on digital sampling is still extremely relevant: https://www.xiph.org/video/vid2.shtml
I again saw a video today claiming that the quality of a digital signal degrades as you approach the Nyquist frequency (half of the sampling frequency). No. That's just not true. A band limited signal, containing information of to a frequency f, can be captured *exactly* by sampling it at any frequency larger than 2f. If you sample a band-limited signal according to this limit and then pass it through a digital to analogue converter you get *exactly the same thing* as you started with. Even if it contains data at 22 kHz and you sample it at 44.1 kHz. (But you really want it to contain nothing above 22.05 kHz or it will be aliased and you will definitely lose data).

I've recently become a big fan of the Opus audio format. Before this week, I'd probably never knowingly used it. I started using it because I was using youtube-dl, and using the default for highest quality for which .opus is often the format. #opus #Xiph #XiphOrg #freesoftware

This is the stuff that gives me hope for humanity. The level of technical and advanced stuff that goes into this and makes something truly useful and astonishing and inspiring. Always amazed whenever I read stuff from #Xiph Fountadion .
