  • Amplifier matching in a digital amplifier modeling system
    Patent number: 11164551
    Abstract: In one example, a method to match a digital amplifier model to a real guitar amplifier comprises obtaining an amplifier output filter and an amplifier input filter for the real guitar amplifier, using the amplifier output filter and a model output filter to obtain a corrective output filter, using the amplifier input filter and a model input filter to obtain a corrective input filter, and applying the corrective input filter and the corrective output filter to the digital amplifier model. The amplifier output filter and the amplifier input filter can be obtained using exponential sine sweep (ESS) and a matched filter. Other examples and related methods and apparatuses are also disclosed herein.
