CiCueDenoise

CiCueDenoise is a denoiser that applies a memory-less expanding nonlinearity to each CQT coefficient. Low-amplitude components are reduced, and high-amplitude components are preserved. Its structure is very simple, but it works well on tonal material, and its artifacts differ from those of conventional DFT-based denoisers. Its 10 control bands are spaced logarithmically from 0 Hz to Nyquist.
