How can i scan this and have values read into a text file, like
Freq Vol
20 0,00
23 0,04
...
20000 -12,2
? Is there a software for this type of thing?
Note: for actual speaker calibration I'll use omnis, of course.
You're viewing a single thread.
By the way, i used to live not far from the Oktava factory. @_jayrope, if you will need it, i can help you to buy their microphones from the manufacturer, including those that are no longer in production.
@ivan zlax Thank you, Ivan, for the offer.
@ivan zlax Hey Ivan, i hope, that you are doing fine. One thing I would love to pass on to the marvellous engineers at Oktava is, that their microphone clients would benefit a lot from finding data sets/value lists of their frequency diagram on a dedicated Oktava page.
If such lists were available upon entering a serial number into a page on their website, then customers could escape a lot of the possible errors, when doing a manual scan yourself.
Here's an example, scanned from the lower one of the diagrams above:20.2486 -3.7746

And there's a link to the techspec there too.
If you need the data exactly in text form, as you wrote above - i think it is better to make an email enquiry: [email protected] (it's an "export" mailbox, so you can write to it in english)
