suppot - unlock the graphFFT and mono2FFT resolutions
by tester » Fri Mar 01, 2013 7:28 pm
Hey support, we are discussing some things regarding multiple peak finding in spectral domain at high resolution and we came to a point, where you should probably do something.
1. Unlock "mono to FFT" primitive - it seems to take not more samples than 44100 samples (what interesting - at SR higher than 44.1kHz too? Don't know, used SR selector with directsound output on board instead of asio - maybe this was the reason; anyway - selection independent from SR would be useful) - it is needed for proper windowing.
2. Unlock "graphFFT" primitive or add an input node for selecting user window sizes. Right now it seems to be limited to 16384 pts resolution and nothing can be done about it. It would be good to have at least 256k pts or 512k pts max resolution.
or
Please provide alternate ways to deal with high resolution (live or non-live) spectral measurements.
