Still no SoundCloud scrub/skipp long tracks....all other competition can do it.

Welcome.

I'd suggest raising a feeback request from the '... More / Feedback and Tickets' menu in the wiim app with details of what you'd like to see.
I have to admit that I'm not entirely sure what you mean by scrub and why it / skipping seems to be an issue just with long tracks.

Hi, when will you do something about the YouTube Music Premium app in the Wiim Amp Ultra menu? I can't add or remove songs from the list, only listening is available... Regards

 

[Goodnews]

Anyone tested the new auto amp pro/sub pro alignment?

Yes
The process is presented in a completely different way, both audibly and visually

 

[Goodnews]

Is the sub/main sync done using the mic at the listening position (phone or calibrated mic)?
The old way of doing it used a mic built into the amp...

That’s a question I’d also like to have answered.

However, the external software that allows you to do this costs over €300. That’s almost the cost of a WU and half the cost of a WAU.

REW is free

Requires a PC
While Wiim Software isn't perfect, it is clearly more practical

Which software were you thinking of that doesn't need a PC? Doesn't everyone have a PC? You only need to do it once unless you move the speakers.

The new fixed version of sub/speaker sync does use the phone mic or external mic.

Did you know that if you tap the "Like" button, you can add that track to the "Highly Rated Tracks" playlist in the YTM app? And if you tap "Unlike," you can remove it from the playlist.


I think good at you add the track to this list for now, and then add it to another playlist in the YTM app later.

My perspective is a bit different.
The Wiim Amp Ultra is a standalone device; the Wiim Ultra is a streamer/DAC.

The comparison should be made within this segment, and in that regard, I’m on the same level as DIRAC.

No. Many youngsters just have phones. Hence the focus on the wiim home app and every other means of controlling your Wiim system is just an afterthought.

I must be getting old

I must be getting old

I was late to computers. My first one was second hand. I think it had 512 mb RAM, Ubuntu 7.04 and ran the old slimdevices slimserver software with 2 squeezeboxes no problem at all.

I think my car keys have more processing power than that now,

Thank you

By scrub/skipp I mean that when you listen to some song, or in my case where I listen long DJ sets, you can skip to some time position in that track. It's pretty normal to be able to do it, except with Wiim and thats a huge let down, because I need to listen that long tracks from the beginning every single time.
I have HEOS system, it can do it....I have Eversolo system, it can do it....only Wiim can't....

I just re-ran Roomfit, but I always get an error.
There always goes something wrong when it wants to measure the right speaker.

This is often due to local issues with the phone and app.

Some don't like to hear this, but rebooting your phone and clearing the cache of the WiiM Home App (if you're on Android) often cures this.
