Advantages of using Fixed resolution?

[Smartplug]

That option does not exist for my WiiM Ultra.

I didn't try setting my phone to Polish language, though.

It does I have it on my ultra. You need put location on ultra like bedroom then you will see the option.

Android or iOS?

I conclude that this setting is simply superfluous for Android as Chromecast will always use the "full dynamic range" (whatever the restriction posed by the opposite might actually be).

There may be another reason. I read somewhere that Google stopped supporting Chromecast Audio. Maybe that's why it's not on Android devices. Maybe they left it on iOS on purpose? A few years ago I read on some forum that this setting is important for high sound quality, because the default is low quality.

Nope, not on Android.

Why would they leave it on iOS?

Chromecast Audio was a product, which Google stopped making and eventually supporting. Chromecast built-in (as it once was called, I have no idea if or how many times they might have changed the name) is a different story (but also audio only).

And it's lossless, currently supporting 16 bit 48 kHz using the Ultra. I cannot imagine what dynamic range would need improvement here.

Interesting, listening qoboz using chromecast is louder than using wiim app using same volume setting.

Chromecast audio on other WiiM devices supports up to 24/192 despite that (outdated?) spec. WiiM are working on improving Chromecast for the Ultra.

When I use chromecast on qoboz app, high resolution doesn’t show number even on wiim app. I’m not sure what resolution it’s playing. This is on ultra.

A while back WiiM removed bitrate/ resolution info for Chromecast from the WiiM app as they couldn’t be sure it was accurate. However, from memory, the Qobuz app will show the playing resolution albeit just up to 24/96 as that’s what its app caps Chromecast at.

My understanding is that "full dynamic range" is the normal audio output. Nothing special. Turning it off narrows the range and eliminates distortion on small speakers, etc. It may look a little like normalization.

Yes, someone correct me if I am wrong.

The qoboz app when I play high 24/96 via chromecast it’s down sample it to “cd quality” I tried several music and all came the same cd quality. If I play it via wiim app it play on its native resolution. I’m not sure why chromecast down sample music to cd quality. Now, if I play it on my my phone it’s fine with correct information.

I tried it while playing music using toggle on and off it did not change any behavior from loud to soft passage. There was no effect. To me it’s just light show thinking you get full range.

Yeah, sorry that’s currently a restriction with Chromecast (or CastLite) only on the Ultra - should’ve mentioned that…

Hmm, ultra got less quality chromecast than the rest of the wiim. That’s suck!

If fixed resolution is upsampling everything, dose that mean the Wiim dac is being used and not bypassed although I am using digital out on my Pro.

No - a DAC converts digital to analog by definition and if it the output is digital, I’d say it’s not being used and that the upsampling is being achieved computationally

To my opinion the only way I would use such feature if your hearing pop and click when changing music with different samples.
