Sorry, if it may sounds obvious...I'm actually quite new to Kyma...
I am wondering how to converts a linear frequency spectrum input into a logarithmic frequency spectrum output?
There is a SpectrumLogToLinear prototype but no SpectrumLinearToLog?
Anybody know how to achieve this?
Thanks!

If you use 'SpectrumInRAM Harmonic' there's a checkbox for Log (vs linear) frequency.

Thanks for your answer!
This isn't exactly what I am looking for because I will have to use a spectrum analysis file.
For example, I want to convert it after a "LiveSpectralAnalysis" sound and I get an error from "spectrumto linear". But I have found that I can delete the "spectrumtolinear" and it works.
I 'm trying to rebuild this sound file from "jedsound": http://jedsound.com/blog/?p=116
There is a "Log magnitude" which seems to do a linear to log conversion and I can't figure where to find it.

LogMagnitude is in the Prototypes (in the Math category).

Weird but it isn't in my prototype library...I attached a screenshot.

Here it is (sorry, it looks like we had thought it was no longer needed).

Great!!! Is there a way to import it in the prototypes system? That's the part as a newbie i never explored, I searched quickly and I haven't found it.

I also see that it's now not possible to create a custom prototype from the menu->new as mentioned in Kyma Revealed.

To open a custom Prototype strip:

Create a Sound file with your new Sounds. To categorize them, gather them into SoundCollections; the name of the collection will be the name of the category in the custom strip.

Do a File>Open with file type: Custom Prototype selected.

Then select your .kym file.

It opens as a Prototype strip with all of the system prototypes PLUS your new Sounds organized in categories named for your SoundCollections. Any Sounds that were not in collections appear in a new category called General.
