[Completed Beta] Automatic timing alignment for Main Speakers and Subwoofer

[slartibartfast]

The latest version in app store is now 2.12.1...so use that version if interested in beta testing?

Have you got the firmware yet?

I’m counting on you! You and I are among the hardcore on rc.

No not yet. I just went to get the app updated and noticed the difference.

Let's see if WiiM respond to my question about firmware availability.

No not yet. I just went to get the app updated and noticed the difference.

Generally, some features might require a beta version of the app alongside the beta firmware, others will not. It all depends.

In case of this beta programme WiiM explicitly say to install the "latest version" (which happened to be 2.12.0 at the time they posted). You can be pretty sure that any newer version should do. Otherwise automatic updates through Google Play would break the beta programme.

I strongly recommend that anyone using subs with the Ultra or either Amp should sign up for this.

There is no need for me to do this because the individual drivers in my speakers are already digitally time aligned and then those are matched to two subs. The speakers are large home built open baffle, so I needed to correct time alignment myself with four drivers per speaker together with two additional drivers per sub.

If anyone is interested but unclear what the process involves using OEM speakers and subs, a simple summary of my own arrangement below:

Measurements of my system at head height, listening position:
Largest sub measures 37.9ms
Second sub measures 35.7ms - requiring a 2.2ms delay
Main speakers measure 33.8ms - requiring a 4.1ms delay
All are therefore 'corrected to 37.9ms (but only at that one 'sweet' spot in the room).

Time alignment makes a very significant impact on the correctness and realism of the overall sound. Subs produce long wavelengths compared to main speakers, therefore treble frequencies arrive at the listening position first, mid range frequencies follow and the bass will be 'slowest'. The WiiM approach will allow overall delay to the main speakers to align with the subs (effectively aligning treble with bass, assuming well designed speakers already have a degree of inbuilt alignment among the varying drivers). I'm not sure what the WiiM technique will be but if it includes impulse graphs then the commonly used (& used by me) practice is to match the timing of initial impulse peaks. An alternative school of thought tries to match the initial rise point, not the peaks.

If done precisely in combination with room treatment the Crossover point will be undetectable & there will be no single frequency that 'jumps out' or dominates during listening, just a continuous and smooth representation of real music and voice. Time alignment really can be a 'game changer'

Woud be great.. looking forward to this excellent feature

 

[BK308]

I would like to try this feature. I think I’ll sign up after I get home from work.

Where it says the firmware for the WiiM Amp is "Coming next week" is that this week (beginning 21/10). It sounds like it should have been released on Monday 21st but no sign of it yet. When it does arrive will it also include the latest updates from the recent official firmware update?

The update was posted yesterday and should have already started rolling out to devices, here's the thread in case you haven't seen it yet: https://forum.wiimhome.com/threads/wiim-amp-firmware-v5-0-633164-update-oct-21-2024.5200/

Ah so is it included in the latest official firmware? I thought it would be in beta firmware.

I just checked in and it looks like they're testing out another build first before it gets into the official version. I believe that build will be 5.2.632652 but I don't think it's gone out to everyone yet. I'll let you know if hear it's on the way (or Wiim Team can jump in if they get here first).

I wouldn't expect a beta feature to go to everyone. We registered to test a beta and so far no beta firmware has arrived.

Beta and official don’t mixed together. If was released on official it would be noted on release note.

Hi Team,

For Beta testers using WiiM Amp, we will whitelist your device for the Beta firmware either later today or early tomorrow. You can use the latest official app alongside this Beta firmware for testing. Last week, we released the Beta firmware with this feature for WiiM Ultra Beta users as well.

Just received 5.0.633341 so will test later. I noticed it isn't marked as beta so will be a pain to leave at a later date.

Let us know how it goes.

 

[slartibartfast]

Just tried it. It doesn't tell you which microphone it is using which I thought was strange. I used the iMM6. It plays a high tone followed by a gap then a mixture of tones another gap and finally a low tone. The automatic result was 8ms latency adjustment of the main speakers. My previous manual adjustment was 6ms latency adjustment of the subwoofer. I have no idea about the methodology behind the automatic setting or if the setting is correct or not. It sounds fine to me with both settings.

Was the 8ms consistent if you run multiple sweep?

I knew you would ask that. Three times with the same result.

If you and others don’t find issue it may go to public release sooner.
