The range is 6Hz to 96kHz. I always wanted to see what's beyond the audible range.
The resolution is 2x that of Reason's SA. First I tried to make it evenly dense on the logarithmic frequency scale, and it even worked, but the latency at the low frequencies was too high (3 seconds). I had to make it the usual way. There is still a use for that evenly dense approach, in a spectrogram device, for example, where the latency does not matter.
