The Sound Recordist involved sent it back and went back to the ordinary CMIT's which are great.
I don't know if they have improved it since, but I would not go near it again after that experience.

Yeah, I usually ask recordists to always record the second unprocessed channel if they insist on using that mic. But then the problem is that 99% of boom work is wireless nowadays and sending two signals via AES42 from the boom is not an option most of the time.

Don't like that mic either, and I generally love Schoeps mics

Auto Align Post V2 is generally working well here, had a couple of occasions where it creates clips that sound chorused though, having to keep an eye out for that. Pure guess that that's the all pass filters working too hard.

It was almost impossible to align those tracks in the old days. because the phase was different in the lows and highs. I guess that's the main reason for the new version improvement.

Interesting. I personally never was really convinced by the superCMIT (and its price).

And just like Pete mentioned, I too noticed with v2 some delay/chorus behaviour on certain material. Reimporting and re-processing it fixed the issue.

One issue I have had with the v1 plug is that I get these clicks in the 100-200 range from time to time. Not often, but enough that it was annoying. Had one today, and tried the new version on the same material. Click was gone. So it seems to work better I think.

yes. Great update and I did not have to pay really anything for it. $99 upgrade was a deal, but it's worth it at any price.

Definitely a plugin that's become one of my indispensables. Simple, quick & effective.

Tip for the SuperCMIT:

A dx editor I know recently told me that after a bit of comparison the "old" workflow of first using the FIR filter (from the Schoeps website) on the SuperCMIT and then either AApost 1 or 2 still sounds better than the AApost v2 alone so that mic is still a tricky one even with v2. Maybe they need to implement a dedicated SuperCMIT mode that has the FIR filter built in.

Hi Frank, could you explain your workflow with the FIR filter please.
I found it here:
https://schoeps.de/fileadmin/user_up..._FIR_48kHz.zip


We have an upcoming project where most of the dialog is captured with a Super CMIT. The production sound mixer is recording the unprocessed sound as well. Does one need the FIR filter for both processed an un processed outputs? How do you implement the filter during editing? Do you use the filter when the Super CMIT is source for auto alignment as well? (we mostly align lavs to boom)



Concerning the Auto Align issues with phase in the first version, we noticed that having different frequency HPF on tracks could throw the alignment off i the low end, so we started advising location mixers to keep HPFs at same frequencies on all channels. With v2 that will probably be not necessary anymore (still have to investigate further as it's early days, but first experiments looked good).


I tested the Super CMIT on location when it was released to the market and wasn't very impressed by it at the time. I haven't come across one in projects since, but that will change in December this year, so I'm very curious how you and your dx editor handle it in post, especially with Auto-Align.

Hi Thierry,

so he uses this

https://auroradsp.com/en/strona-glow...se-loader.html

It renders the processed signal (it will be 6dB lower after but you can pull that back up again) and then does the AApost alignment.
But I guess Altiverb would work too as a convolver.

The INV FIR will correct the group delays before you use AApro.

I don't think the unprocessed output needs it but I can't say for sure.

Thanks for the link. Apparently the unprocessed output doesn't have the same issue. We were researching it this WE after your remark and one of our sound engineers found the thread below on the Jeff Wexler forum, with an answer from Helmut Wittek (Schoeps) himself:



https://jwsoundgroup.net/index.php?/...issues/&page=2


And I quote:

"Posted December 31, 2016:

I was pointed to this thread about the SuperCMIT latency and I'm happy to comment.
When we designed the SuperCMIT in 2010, we opted for a minimum latency for ch1 at higher frequencies and accepted the compromise that the latency got frequency-dependent. In practice we found no real disadvantage (loudspekers also have a frequency-dependent latency), but nevertheless we told our customers to keep it in mind.
It has always been more a theoretic issue, no practical user identified it as a problem. Actually, there has been one sound engineer that wanted to experiment with the SuperCMIT, ch1, in M/S, where you really need exact phase alignment. For this guy we produced the attached compensation FIR filter.
Remember that the normal CMIT signal on ch2 of the SuperCMIT has a normal, frequency-independent latency. So whenever you need to mix a lav with the Super, simply choose ch2!
When using the SuperCMIT, in my guess 90% of the users use ch1, Preset1, 5% use ch1, Preset2 and 5% ch2. Usually ch2 is only recorded as a backup when the situation makes you doubt the algorithm or when you want to offer an option to post."
