Maxium 24bit/192khz or 24bit/96khz

[Ptk9]

Hi guys,
I'm new here on this forum.

2 questions:
1. If I stream 24bit/192khz music files that are stored locally on my mobile to the Wiim Pro, will they also be played in 24bit/192khz?
(I do use the internal DAC from my receiver)
Is this via Chromecast audio protocol?

2. Can the built-in "chromecast audio" handle 24bit/192khz files?
I ask this because the original "chromecast audio" can only stream to maximum 24bit/96khz music files.

Thanks in advance for your support.

Regards,
T.

Afaik all Chromecast streaming regardless of device/manufacturer is limited to 24/96

Thanks for answer my second question, and my first question?

If it's from WiiM home app then it will play the max quality whatever the file is and your settings in the app.

Thanks, all my questions are answered, have a nice day, regards, T.

It is possible to get 192 over chromecast, e.g. Roon.
But for all intents and purposes, expect 96 to be the max.

re. 1) "Is this via Chromecast audio protocol?" That would all depend on what app you use / target renderer type you choose.
For example, using bubbleupnp on android you can cast to a wiim as either upnp or chromecast target.

If I recall when I first got my Pro, I could ChromeCast 24/196 files no problem - it was only when I tried Qobuz that its app capped it at 24/96. I think the presumption that CC is capped at 24/96 comes from the limitation of the ChromeCast audio devices themselves whose hardware limited anything higher. Try it

but when you play a 24bit/192khz music file in the Wiim app, the music file is always played in 24bit/192khz?

Yes.
Unless you use digital outputs and cap them.
The 'now playing' screen shows you the source details.

 

[Ptk9]

Sorry, but what do you mean with "Unless you use digital outputs and cap them"?

 

[Mr Ee]

You can set the max sample rate / bit depth that the wiim will output, per digital output.
e.g. if your external dac supports up to 96 khz you can set this so that a 192 file played to the wiim will be downsampled to 96 so your dac can play it.

I don't have any first hand knowledge, but according to Wikipedia I would assume that 96 kHz/24 bit is a limitation of the Google Cast protocol, indeed.

Supported audio codecs are HE-AAC, LC-AAC, MP3, Vorbis, WAV (LPCM), FLAC (up to 96 kHz/24-bit) and Opus; AC-3 (Dolby Digital) and E-AC-3 (EC-3, Dolby Digital Plus) are available for audio pass-through.

Edit: This is obviously not correct, see below.

Okay,

You can set the max sample rate / bit depth that the wiim will output, per digital output.
e.g. if your external dac supports up to 96 khz you can set this so that a 192 file played to the wiim will be downsampled to 96 so your dac can play it.

Thank you Mr. Ee

 

[Mr Ee]

Okay,

Thank you Mr. Ee

No worries.
A number of dacs (and amps/receivers etc.) don't support 192 over optical.
Some say they don't, oficially, but actually can - 192 over optical can be troublesome at times!

I really only mentioned all of this 'cos you wrote 'I do use the internal DAC from my receiver', but didn't specify optical or coax.
Wasn't sure if you were asking (in a roundabout way!) 'cos you were having issues at 192!

I use a coax cable, so no problems with 24bit/192khz music files?

Should be absolutely fine.
Only time I ever had issues with my coax (occassional dropouts) was when it wasn't plugged in fully.

Enjoy!

Chromecast Audio Review

Wire from the Cloud – With Chromecast you can stream music from Qobuz & Co. directly from the cloud to your streamer – without a PC and in HiRes. Soundwise that should be ideal.

Later on if I get a chance I’ll post some screenshots of Chromecasting a local 24/192 track to my WiiM pro/Plus

Of course, ymmv

Here is a screenshot of a local 24/192 file being ChromeCasted (not upnp) to My Pro Plus using BubbleUPNP on my android phone. My amp/DAC showed it was indeed receiving 24/192.
