Hi! I think I should write some notes about how circuit modeling works in Kirchhoff-EQ. There are two methods for circuit modeling. The key is how to treat the non-linear distortion of the circuit. If we consider nonlinear things in the circuit, some kind of numerical integration should be used(as many many simulations did). Numerical integration […]

Some notes of Psychoacoustic Adaptive Filter Topologies About 15 years ago, I made a simple eq in matlab when I was studying on DSP. Compared with some famed commercial products, I was surprised that their sounds are much, much better than mine. After more study and research, I believe there’s no magic in their algorithms, […]

Some notes of Harmonic Shifted Envelope When we say “compressor” or other types of dynamic processing, what do we actually mean? We means amp modulation. Yes, all dynamic processings use a curve to modulate audio volume, which is indeed amp modulation. For amp modulation, when a envelope of frequency A to modulate the signal of […]
