| | 180 | ͏ Note it's noted in the documentation that "is not designed for real time" use: mostly due to performance cause.\\ |
| | 181 | ͏ [ !^ Likely implementation issue: this should be similar (or simpler) [1] comparing to "fftdnoiz". ]\\ |
| | 182 | ͏ Might worth notice to who considering performance in selection of denoise algorithms.\\ |
| | 183 | [ [1]\\ |
| | 184 | ͏ Unsure if "fftdnoiz" uses DCT or DFT:\\ |
| | 185 | ͏ FFT may compute both. ] |
