Change Deezer streaming codec from MP3 to AAC
At least, for now, it isn't on our plans, but we haven't closed the doors for it 
I hope it eventually comes cause I love everything about Deezer except the codec you still use. Ogg is clearly better, miles better. Right now I use spotify and the change in space occupied by the same music is huge. Right now spotify is using 5.5 GB (I have a lot, a lot, of musics downloaded xD). The same quantity of musics would be like 3x that, which is a lot. The deezer UI is so much better, more modern, easier to use and less cluttered. Spotify has the same UI for years. Its cluttered with multiple menus that arenāt adding anything. But that Ogg on spotify is miles better. Better sound quality and clarity.
Do you see Ogg codec coming to Deezer in maybe 2 years at least?
You sound like a customer who may benefit from Deezer Hifi. One year annual plan discounted.
It has BEST quality. Even better than Spotify has ;d
Perhaps you are interested?
Search on Google āDeezer Hifi sonos dealā and you will find it!
I've heard this claim about AAC Bluetooth pass hrough before, but I haven't been able to find a reliable source to back it up, and I've also heard that AAC audio is recompressed a second time with AAC anyway and still loses quality. Cam anyone give a definitive answer for this?

AAC is superior to mp3 by every stretch of imagination, it gets better fidelity at the same bitrate, (like when comparimg a 256kbps mp3 vs a 256kps aac, aac will be better), it would also occupy less space in this same scenario, so basically AAC gives you better quality in less space.
You can even let the AAC Codec at a variable bitrate in a way that it would be able to reach well over 500kbps when its needed, like when theres a big crescendo in that classical concert with 300+ instruments, originally recorded in 192khz and converted from 5000kbps FLAC to AAC. That gives you even better quality than mp3 can ever dream of achieving.
But you need to convert the original source or at least a lossless version like FLAC to AAC not an MP3 file to AAC, that would be recompressing, also, quoting our friend Mark, AAC is a native codec over bluetooth, that basically means thats the codec bluetooth 4.0 aptx runs at, that means anything else will be encoded into AAC passing through a recompression as you mentioned. But that shouldn't take that much off of the music if you're converting from MP3, should still make a little difference. But it wouod be really hard to make a comparison.
It might or might not make a difference in latency but that depends on a lot of things so I wouldn't count that as a plus for AAC,
+7Thank you for your votes! We passed your feedback on to our devs and they decided not to work on it at the moment, however, we will keep this topic posted about it if things change in the future!
Having just switched from Tidal, the difference between MP3 and AAC when using BT headphones transmitting with AAC is quite noticeable. Quite a drop in quality. This makes me sad. Looking forward to iOS HiFi and AAC in future!
Good time of the day.
I am happy with 320K, but Iāve seena trend when streaming services change 320K MP3 or OGG for 256K AAC. I do find AAC better, and it even sounds better than same bitrate MP3. But please Deezer please if you change to AAC do not change to anything less than 320K AAC!!! Make it the best experience, do not accept less. Many basic users expect to have 320K, not 256K and who else is going hifi. I do not want to pay more, I want 320K only. Just my word and voice around it.
+9Thanks for sharing this detailed feedback, 
There are many claims about the quality of different codecs, most of them based on empiricism only.
For example, I have a mastering-grade DAC with studio monitors and my trained ears still struggle with hearing the difference between 128k MP3 (pop music, professional encoder, VBR) and the original file. 
It might be easier to hear the difference for classical music, though.
In any case, for scientific and blind-tested results I recommend to have a look at http://soundexpert.org/encoders. You can improve their results by simply downloading and listening to a sound file, too. 
AAC is leading all of the quality ratings I have looked at (which shouldnāt surprise anyone who knows a bit about the internals of MP3 and AAC).
+9Thanks for sharing your knowledge and opinion with us
Will pass your comments on 
I second this. OGG Vorbis/AAC give better sound for the Bitrate.
If you donāt want to fully switch to Vorbis, you should REALLY consider it for 64 and 128 kbit/s
You can try it for yourself: encode the same piece of music as .ogg, .mp3 and .aac (64 kbit )
mp3 sounds terrible, aac sounds bad/ok-ish, .ogg doesnāt sound that bad (losing precision, but no extreme artefacts)
Maybe I can find something nice and royalty free to use and link as an example later (currently on mobile)
Bluetooth is also a good point.
Deezer, AAC, please =) Itās the only way to enjoy music in wireless headphones on iPhone.
+8Deezer is currently re-encoding their MP3 catalogue to enable gapless playback with this format for the most listened songs and albums, so it is very unlikely that they will do this again to support AAC or Ogg Vorbis.

+9Thank you for your detailed feedback - our developers love these comments to help them understand real needs.
It's really hard to say if we're going to go for that format, in Tech all can change very rapidly. But please subscribe to the topic so that you're kept up-to-date with developements

+9Ogg maybe, but it's a no for AAC. It doesn't represent better value from MP3 for the effort required to implement

Iām a free user so I understand that Iām not exactly a āpriorityā, but I would love it if Deezer could implement this.
I recently had to abandon Deezer when I realised just how much better the quality on YouTube Music was. I seriously thought I was going deaf using Deezer. To my surprise, I found out that both sites offer 128kbps on the free tier. So naively I thought, they should be the same, right? Thatās when I learned about the differences between MP3 and AAC.
Itās a real shame because Deezer is drastically superior to YouTube Music in every other way. But alas, sound quality is more important.
One way they could do that, is to raise 128K to 160K MP3 on Free tiers.
I do not think they will change codec anytime soon.
