    • A computer implemented method for improving audio, comprising processing audio with a combination of wave adjustment tool WAT and a collection of preset settings for adjusting specific harmonic content to specific genres of music. The preset is selected from the group comprising different genres (styles or types) of music; auto-preset; and generic preset. The auto preset value is determined by the metadata which is commonly included in an audio file. In the event there is no match between the preset genre names and the one in the metadata, then the selected preset will be "Generic." This particular genre preset is designed for optimal sound across many genres, making it generic.

    • A device for determining the quality of an ouput signal to be generated by a signal processing circuit with respect to a reference signal is provided with a first series circuit for receiving the output signal and with a second series circuit for receiving the reference signal and generates an objective quality signal by means of a combining circuit coupled to the two series circuits. The poor correlation between said objective quality signal and a subjective quality signal to be assessed by human observers can be considerably improved by reducing, in a differential arrangement, present in the combining circuit, for determining the difference between the two series circuit signals, said difference by a certain value, preferably as a function of a series circuit signal, and the poor correlation can be further improved by disposing a scaling circuit between the two series circuits for scaling at least one series circuit signal, it is furthermore also possible to scale the quality signal as a function of said scaling arrangement.
    • 用于确定由信号处理电路相对于参考信号产生的输出信号的质量的装置设置有用于接收输出信号的第一串联电路和用于接收参考信号的第二串联电路,并且产生 通过耦合到两个串联电路的组合电路来实现客观质量信号。 通过在组合电路中存在差分布置来减少用于确定两个串联电路信号之间的差异的所述目标质量信号和由人类观察者评估的主观质量信号之间的差的相关性可以被显着改善,所述差异 优选地作为串联电路信号的函数,并且通过在用于缩放至少一个串联电路信号的两个串联电路之间设置缩放电路可以进一步改善差的相关性,此外还可以对 质量信号作为所述缩放装置的函数。
