Deezer HiFi - 16-bit 1,411kbps

[Phooey]

Just noticed Deezer are doing a CD-quality lossless service. I'm new to music streaming services but am I right in thinking to get this CD-quality audio I just need to simply purchase a device (bluetooth speaker) and then subscribe to Deezer HiFi?

I read somewhere that it is only 320kbps when "downloaded to phone". Does this mean to get 16-bit 1,411kbps quality you have to stream direct to blutooth speaker from your home wifi - so basically not using the phone (Iphone in my case)? I'm confused

No idea on the Deezer thing, but Bluetooth cannot do CD quality / lossless audio in any real products that I know of.

The best it can do is typically 320kbps for a handful of supported codecs. Some sound better than others

The iPhone can use AAC and SBC as Bluetooth audio codecs, Android phones generally support SBC up to 320kbps to most Bluetooth accessory devices.

The aptX codec is supported on some handsets and some accessories and this offers a flatter frequency response across the audible band but is ultimately still compressed (don't let anyone tell you otherwise). It also uses more over the air bandwidth and is a higher complexity codec which can result in reduced range / more dropouts and shorter battery life (e.g in headphones) / a trade off for the increased frequency response.

In all cases there is some re-sampling / rate adjustment going on as well to compensate for differences in the underlying clock frequencies which cna be audible in my experience (in the Bluetooth industry).

Does Deezer Hifi only play the CD quality music on the devices listed on their website, or on all devices, eg in my car, or simply through headphones?

I know they only used to offer it for Sonus products, but there are now more devices listed, but I would want the improved quality in my car and headphones too to warrant it.

Cheers Bob.

Apologies if I've misunderstood but basically are you saying I won't be able to stream CD quality audio from my Iphone to wireless speaker? It's quite confusing and I can't seem to find an answer online.

Deezer are saying you need a sound-system which supports Google Cast, but if you can only stream at 320kbps it all seems a bit pointless?

To be brutally frank, is there really a need for 16/44 when streaming to a wireless speaker?

I don't know - does it not depend on the quality of the wireless speaker?? B&O do a few quality pieces which I'm sure would sound better for 1411 than 320 for example. Happy to be corrected / taught before I part with some cash

A wireless speaker can be good quality and support FLAC. They list some on their site. Controlling the music it streams, using a phone, would be ok. That's not the same as streaming from a phone.

Cheers. I need to do some reading up. I'm basically looking to purchase one of the B&O Play products and from what I can understand is that as from October they will support Deezer HiFi. So I guess the best way of streaming would be from the app built into the B&O Play speaker and using my iphone to change tracks etc?

Probably. You might find some of the apps expect an iPad for full control, rather than an iPhone, but have a read.

Deezer Elite, or Hifi as it is now called, could only be played in Flac quality through certain devices. At the time I subscribed this was only Sonos products but it may be more now. On all other devices it was 320 bps.
