摘要翻译：
许多音响系统为音乐家昂贵和笨重。因此，对它们进行建模并用计算机仿真来代替它们是有利的。在吉他演奏者的世界里，音频系统可能具有理想的非线性行为（失真效应）。因此，很难找到一个简单的模型来实时仿真它们。Volterra级数模型及其子类是非线性系统建模的常用方法。不幸的是，这些系统很难用分析的方法识别。本文提出利用神经网络的新进展，对其进行实时仿真。实验结果表明，管放大器信号与神经网络输出之间的均方根误差小于1%，可以达到精确的仿真效果。此外，该研究还扩展到放大器增益参数的建模。

英文摘要：
Numerous audio systems for musicians are expensive and bulky. Therefore, it could be advantageous to model them and to replace them by computer emulation. In guitar players' world, audio systems could have a desirable nonlinear behavior (distortion effects). It is thus difficult to find a simple model to emulate them in real time. Volterra series model and its subclass are usual ways to model nonlinear systems. Unfortunately, these systems are difficult to identify in an analytic way. In this paper we propose to take advantage of the new progress made in neural networks to emulate them in real time. We show that an accurate emulation can be reached with less than 1% of root mean square error between the signal coming from a tube amplifier and the output of the neural network. Moreover, the research has been extended to model the Gain parameter of the amplifier.
