It's like a filter version of a wavetable. Complex filtering that is difficult with conventional methods can be easily performed.

Exp Filtertable achieves complex filtering with exceptional sound quality by adopting a convolution-based approach, similar to commonly used linear-phase EQs, rather than the STFT-based method often found in typical spectral effectors, which can easily degrade sound quality. This approach avoids the inconsistencies and response fluctuations caused by misaligned STFT blocks, ensuring a consistent, complete response and phase at all times.
