摘要： The invention provides an audio signal processing system for simulating sound engineering effects. The audio signal processing system may simulate, emulate or model sound engineering effects that may be present in a sample audio signal contained in a sound recording. The audio signal processing system may include an input signal, a first filter system, a nonlinear effect simulator and a second filter system. The input signal may include an audio signal and the sample audio signal. The audio signal may be a signal generated with a musical instrument and the sample audio signal may be a previously processed signal for a sound recording. The first filter system may include a chain of filters configured to condition the audio signal. The nonlinear effect simulator may receive the audio signal processed by the first filter system and modify the audio signal nonlinearly. The second filter system may be configured to receive the modified audio signal from the nonlinear effect simulator and process the modified audio signal according to a frequency response that corresponds to the sound engineering effects. The sound engineering effects are determinable based on the sample audio signal and the modified audio signal.

摘要： This invention provides a system for customizing musical instrument signal processing enabling users to produce different tonal characteristics in created musical pieces. In order to create such tonal characteristics, a new mathematical model of tonal characteristics may be digitally created based on two or more initial mathematical models of tonal characteristics. After simulating a first and second initial mathematical models of tonal characteristics, the new mathematical model is created by interpolating one or more coefficients of the first and second initial mathematical models. The new mathematical model may also adjust a control parameter where the control parameter may exist between two values. When the control parameter is the first value, the new mathematical model is the first initial mathematical model. When the control parameter is the second value, the new mathematical model may be the second initial mathematical model. When the control parameter is located at a point between the first and second values, the new mathematical model may represent a convergence between the first and second models.
