    • The invention relates to a method of enabling a user to adjust at least a first and a second control parameter for controlling an electronic system. The method comprises the step of displaying a coordinate system on a display screen, a first coordinate of said coordinate system representing a range of values of the first control parameter, and a second coordinate of said coordinate system representing a range of values of the second control parameter, the step of visually indicating a position in said coordinate system corresponding to a currently selected combination of values of the first and the second control parameter, and the step of enabling the user to select a new combination of values of the first and the second control parameter by indicating a position within said coordinate system.

    • In the method of coding the audio signal, the values of first parameters (P1,1), which represent aspects of the audio signal at a first instant (ti), are calculated to obtain first calculated values (A1,i). The values of second parameters P2,i), which represent the aspects of the audio signal at a second, later, instant (t2), are calculated to obtain the second calculated values (A2,i). The number of the first parameters (P1,i) and the number of the second parameters (P2,i) differ. A subset (SUS2,i) of the second parameters (P2,i) is associated with a particular portion (SFRAi) of a frequency range (FR) of the audio signal This frequency range (FR) of the audio signal is preferably selected to cover all the frequencies present in the audio signal. The values (A2,i) of the subset (SUS2,i) of the second parameters (P2,i) are coded based on a difference of this subset (SUS2,i) and a subset (SUS1,i) of the first calculated value(s) (A1,i) associated with substantially this same particular portion (SFRAi) of the frequency range (FR). Thus the differentially coded values (7) of the second parameters (P2,i) are obtained by coding the difference of the values of second parameters (P2,i and first parameters (P1,i) which are associated with substantially the same frequency subrange (SFRAi). This allows to differential code the parameters (P1,I P2,i) even if the number of the parameters changes in time.
    • 在对音频信号进行编码的方法中,计算表示第一时刻(ti)的音频信号的各方面的第一参数(P 1,1)的值,以获得第一计算值(A 1,i)。 计算表示第二,稍后时刻(t 2)的音频信号的方面的第二参数P 2,i)的值,以获得第二计算值(A 2,i)。 第一参数(P 1,i)和第二参数(P 2,i)的数量不同。 第二参数(P 2,i)的子集(SUS2,i)与音频信号的频率范围(FR)的特定部分(SFRAi)相关联。音频信号的频率范围(FR)优选为 被选择以覆盖音频信号中存在的所有频率。 基于该子集(SUS2,i)和子集(SUS 1,i)的差异对第二参数(P 2,i)的子集(SUS2,i)的值(A 2,i)进行编码 )与基本上与频率范围(FR)的相同特定部分(SFRAi)相关联的第一计算值(A 1,i)。 因此,通过对与第二参数(P 2,i)相关联的第二参数(P 2,i和第一参数(P 1,i))的值的差进行编码来获得第二参数(P 2,i)的差分编码值(7) 相同频率子范围(SFRAi),即使参数数量随时间变化,也可以对参数进行差分编码(P 1,IP 2,i)。
