Oh, my, CNN is really full of nitwits. They say: Apple Music will sound worse but save on your data plan. (To be fair, there are a number of tech websites, such as The Next Web, that get this wrong too.)
It just goes to show, digital music codecs are confusing. You can’t blame them for just looking at the numbers. But a bit of research would show that this is simply wrong.
Apple Music will stream music in AAC format at 256 kbps. CNN compared this to other services, such as Beats Music, which stream MP3 files at 320 kbps.
What they don’t consider, however, is that AAC – also known as MP4 – is a much better codec. It won’t sound worse at that lower bit rate; it will sound just as good, if not better, than 320 kbps MP3 files. And, it saves you money on bandwidth.
While they point out that Spotify only uses 320 kbps for paid subscribers (others get 96 or 160 kbps), they still manage to say that Apple Music will sound worse. And they don’t point out that Spotify uses Ogg Vorbis files, which are much lower quality than either MP3 or AAC.
Frankly, I think Apple Music should have an option to stream 128 kbps AAC files, when you’re using it on mobile devices. You don’t need the difference in audio quality between 128 and 256 kbps unless you’re listening in a quiet environment, at home, or on really good headphones.
Couldn’t agree more about the need for a <256kbps stream. Let's be honest… when you're playing music on your stock stereo over Bluetooth, a 128kbps stream will sound just fine.
If you save your music for offline use, sure… send the 256kbps file (an option to allow this only when on Wi-fi would be good here). But otherwise, give users a choice.

I wouldn’t be surprised if Apple Music ends up using Apple’s own HLS (HTTP Live Streaming). This would effectively allow them vary the bit rate depending on a listener’s bandwidth at any given time. If you have a good connection, you get a high quality 256kbps stream and if you’re in an area with poor speeds, it downgrades to a lower quality but smaller stream.

The current Beats Music app has a setting for lower bit rate when on cellular. User selectable.

re – Ogg Vorbis files, which are much lower quality than either MP3 or AAC.
Thats not what I’ve understood over the last few years. My understanding was that OV was similar to AAC at the same bitrate, with both being better than MP3 VBR.
Is there anything out there that shows a recent comparison I wonder.

Once additional thing, AAC is hardware decoded on the iPhone, so will use less battery than Spotify’s Ogg Vorbis files.
Good point.

I’d like even *lower.* I pretty much use my phone as a radio and have an Icecast server at home running HE-AAC at 64kbps. With Bluetooth to the car stereo or earbuds on the train, the quality’s surprisingly good. It goes easier on my data plan and is virtually rock solid on AT&T’s network, especially compared to the performance of iTunes Match.

I see that CNN’s article has a number of comments correcting this mistake. Of course it probably won’t be corrected.

You need to get your own facts straight before criticising others.

Could you provide a reference for Ogg Vorbis beeing inferior to AAC in terms of quality? I couldn’t find any.
Here are results of listening tests at different bit rates. If you use Google, you’ll find plenty of others.
Thanks for the link. Never found this one. However, in my opinion, the difference is not meaningful due to the minimal difference in the range of values representing audio quality between Ogg V and AAC.
Where does it show that Ogg Vorbis is lower quality than MP3? Because I’m seeing the opposite. Please correct your article as it currently states that Vorbis is “much lower quality” than MP3, which looks to be unsubstantiated and false.

I think it’s overstating to say Ogg is much worse than AAC/MP3.
At mid to high rates differences can be minimal.

But as Kirk says (kind of), the audio codec/bit rate dick waving by the music companies is full of ignorance, that’s very true. It’s used to lie to consumers, meanwhile the quality of the source is never discussed.
