Difference between RTA & FFT Analyzer

Post by Vincent Burel »

Spectralissime uses band pass filter bank to analyze audio spectrum, while most of other analyzers are using FFT to do it.

This video below is explaining the main differences between both analysis:

- Spectralissime makes a single measure per band giving the real amount of energy.
- Spectralissime does not need to interpolate data to fit frequency scale.
- Spectralissime provides better display velocity and can better show real time bass frequencies response.
- Spectralissime stays simple and easy to use while FFT provides many parameters for many interpretations...
