Memory Processing and Memory FFT
Posted: Thu Jan 08, 2015 1:30 am
Hi,
Thought it was time to extend the memory functionality a bit.
Here are a set of modules that deal with large memory quite fast. Basically you have to apply one function after the other all connected to the same source/destination memory. I've included an adapted version of the Stream FFT, slightly optimized for batch processing. So you can load in a large memory and then tell the FFT/iFFT to loop through x-times. I've tested it with 32x 2048 FFT + iFFT and it is done in miliseconds.
Most difficult module beside the FFT is the "Memory Merge" module, it can do several different things depending on the inputs. eg. it can copy, do math with two different Memories, and it can combine that with interlacing/deinterlacing. Makes it perfect for dealing with multichannel waves.
Though, there is an important rule when using these modules: Make sure that the input memories are all existing and valid before you trigger the processing function or Copy/Paste the module, else FS says good bye. There is no chance at the moment to find out if a memory input is valid or not, so we have to live with that for now.
Have Fun!
PS: no time to document that stuff... use it or not. It's quite difficult to understand the mess in that schematic, I know!
