Calibration files smaart

I then output 2 columns as a text file lines , first column being the frequency and the second column being the SPL delta from the 3rd worksheet.

I added an extra 0 to the last 2 lines 3rd column as what is in the CS calibration files. Don't know if this is necessary or not. Example Delta Text File: 9. Hope this helps and if anyone has a better way to do it, or corrections, please advise.

DanDan Moderator Staff member. Joined Mar 10, Messages It will typically show a false HF roll off due to cancellation between the tweeters at slightly different distances and other asymmetries. Are you saying that impacts whether this is an accurate measurement of the speaker? Or that it invalidates comparing the mics and using their deviation as a correction factor?

Last edited: Jan 13, Good point and in the context of this thread, it is the difference between the two mics, and not the speaker response in any absolute sense, that achieves the goal of the thread. Joined Aug 14, Messages 1. Reading this, I just want to emphasise that HF measurements are best done with the mic close to a dome tweeter on a diffraction free baffle.

You're in the far field even 10cm away, and this will clean up your response no end. Accurate calibration requires a smooth response from your speaker. Placing a ring of mineral wool around the dome tweeter usually ensures that any cabinet diffraction effects disappear. Sometimes this can prove challenging, usually due to restrictions such as firewalls in your router. At any time, you can revert to the default configuration by tapping the "Default" button on the Calibration Files screen.

The name of the current calibration file or the word "default" will appear on the Calibration screen. Studio Six Digital.
