It seems the format of the calibration file I downloaded from Dayton for my UMM-6 mic isn't compatible with ATF's PC-TOOL's RTA function.

When I try to import it, it just doesn't get applied.

Here is what is in the txt file:

At first, I thought this was structured for PEQ calibration, with the colums being FREQ - Q - dB

But a closer looks has me doubting that, considering the values ...

In either case, anyone know how I can restructure the file to load correctly into PC-TOOL?

Iirc the install folder has a mic file. Save your file as whatever the mic file is in the helix software install so it overwrites.

The new version actually has an import feature in the UI, but it's not recognizing the format of the Dayton file.

I did look at the cal.txt file in the folder, and it's two columns. I wonder if the Dayton UMM6 file just isn't compatible? I was able to import it into REW without issue though.

I have a umik-1 so maybe the format is wonky for the helix. Just a guess, but I'm thinking collum 2 is for mic pointing forward and 3 is 90°

I emailed Dayton asking for clarification ... hopefully they respond.

Here is what I sent:

email_to_Dayton said:
Hello,

I have a UMM-6 microphone, and recently downloaded the calibration file for it. When I look at the contents of the file, it appears different than what I am expecting. I see three columns, instead of two.

I also have a iMM-6 mic, and the calibration file for this is the standard 2 column layout.

When I try to import the UMM-6 calibration file into certain programs, it is not being recognized as a properly formatted cal file.

Can you please tell me the definitions of the 3 columns for the UMM-6 cal file?

Is the 1st column the frequency, the 2nd the Q, and the 3rd the dB?
Or is the 1st the frequency, the 2nd the dB on axis, and the 3rd dB off axis?
Or something completely different?

I’d like to restructure the file so I can import it into my application, but don’t want to throw off the corrections.

Thanks,

So Dayton responded: The columns are frequency, adjustment, and phase.

So I removed the phase, and tried uploading ... and still not working. I then tried reducing the numbers down to whole numbers for the freq and only 2 decimal places for the adjustment, and it still won't import. Then I went as far as to edit the cal file in the PC-TOOL install folder, and just changed all the 0.0 adjustment values to those which most closely matched the frequencies in the UMM-6 file ... and it still won't load into PC-TOOL.

So I sent a message off to ATF to see if they can help.

Hello,

I have PC_TOOL v 4.77a loaded, and am connected to a V Eight DSP mk2. I am trying to load a calibration file for my Dayton Audio UMM6 microphone, but cannot seem to get it to work.
  • The “Original” calibration file came with 3 columns, representing frequency, dB and phase. This didn’t work
  • So I created a “2-Column” file by removing the 3rd column, but it still didn’t work.
  • Then I created a “Truncated” file, by truncating the numbers so the freq is a whole number, and the dB is only 2 decimal places … but it still didn’t work
  • Finally I created an “ATF-Format” file by copying the “cal” file from the PC_TOOL directory, and simply changed the 0.0 dB numbers in column 2, to match the UMM6 calibration for the same frequencies, but it still isn’t working.
When I click “Load Calibration File”, I can browse my PC to the file, but when I select and load it, I am retuned to the RTA screen where it still says “not loaded”.

I’ve attached the 4 calibration files I have attempted to load.

Can you please help?
Thanks,

I heard back from ATF, and this is what they said:

Thank you for your Mail.

At this time we have a problem with the calibration File load function. We will have a solution available with the next PC-Tool update.

Here you find a short manual how to get the Calibration File loaded:
At this time you can do some special workarounds.
At first, please create a new folder in following path: C:\Users\currentuser\Audiotec Fischer.
The Folder must descript exact like this: DSP PC-Tool

The format of the calibration Files must be the same as the CAL.txt folder: C:\Program Files (x86)\Audiotec Fischer\ATF DSP PC-Tool 4.77a
Rectangle Font Parallel Pattern Paper product


After that you can store your own CAL File.
At least I know it's not just me LOL
