Change Deezer streaming codec from MP3 to AAC


For a better audio fidelity experience Deezer should change the streaming codec from the old inefficient mp3 to the newer and more efficient ACC which a.o. enables newer Blutooth headphones to sound better, because no conversion is needed.

So 160 on a MP3 is about equivalent to 128 AAC? Interesting.

To be honest, I didn’t think I’d gain much traction here, I just thought I’d leave my two cents.


As their manager said they are not seeing AAC possible. They’d need 70M tracks to encode.

If that ever happens, they will write out.

If you extremely need free music with best quality, I see that 128K MP3 may not be the best offer.


I tested Hifi Deezer and it sounds better on Hifi on same earpieces. I think it’s because MP3 320K gets re-encoded at loss to AAC bluetooth codec. This said I see that people asking 320K AAC just to avoid that layer. For me I am not going back to non-HiFi service just because of that. Even on Sony high quality €129 Bluetooth no wires earphones the improvement in sound is decent.

 


I am testing out now AAC 320K .

MP3 320K sounds muddy and not clear at all . I feel like on AAC 320K it is much easier to get lyrics and that hype tracks has to provide. There was one or few words I couldn’t hear on Deezer MP3 and now I totally get them when AAC 320K makes the clarity. I do not listen FLAC is it takes too much of my internet and I do not want to have slow internet when it loads flacs all time.

I think, perhaps, they really need to look into it. Sound is what customers seem to want.

The MP3 is good for my dog, one reviewer on YouTube said and I actually laughed.

But now I know why he said that. AAC and FLAC is the future .


The MP3 audio sounds very good, as if LAME 3.100 encoding had been used; it is really transparent.

There is already a request

please everyone who wants aac check out opus and see how you feel about that! Opus is imo a much better undertaking for Deezer as a company and also for it’s listeners considering the BSD licensing!
