Aside from what is stated in the commit description, the last commit also brought back absolute frequency, and added a new PROP_UNIT_FREQUENCY unit to represent numbers in Hz.
More details…
I think a lot of this is already solved by the
Map Rangenode which significantly simplifies the math one has to do. I think the logarithmic scale is not necessary yet. It should be easy…
Personally, I don't really like using relative frequencies. I think it makes it much less obvious what data you get out of this node. Would prefer to keep using absolute frequencies in…
575b26c196f48336b8c411896decc06b96417910 discards bin_index as part of the key of the map, i.e. caches are now continuous like how blender/blender#122228 (comment)…
The last commit refactored the caching system into C++, used std::shared_mutex to achieve thread safety, improved user interface, and removed unnecessary node category.
More details can be…
That reminds me… Yes, it's possible and also very useful. It's very common that a user is expecting to get more details (in frequency, not time) in lower range. That would be hard to implement…
Sampling a range of [0, infinity] with FFT is different from directly sampling without FFT. FFT inevitably decreases time resolution, as depicted below:
 caching structure. The change also allows user to select FFT size by themselves. More details can be found on [devtalks](https://devtalk.blen…
