Reaktor 5 or lower


this spectrometer uses no fft but a filter bank instead. it is not as accurate or analytical but there are some advantages of this method. movements look smoother, the bass resolution is better and there is almost no latency.

version 1.5:
some tweaks and a kind of calibration done.
optional grid, a filter q control.

version 1.6:
no more gaps when used with fewer bands

version 1.7:
optional slower 2nd layer, upscaled version in the b view

Nice work,I just turn down the voices to 256 and the CPU usage is lower.

sure. :) glad to hear this. looking forward to see your instrument. guess the low cpu usage is more a result of the r5.9.3 update.
