    • This invention relates to a method of determining (10) a second sound frame (20) representing sinusoidal components and an optionally third sound frame (30) representing a residual from a provided first sound frame, the method includes the steps of: determining a sinusoidal component in the first sound frame among non extracted components; determining an importance measure (40) for the first sound frame; extracting the sinusoidal component from the first sound frame, and incorporating the sinusoidal component in the second sound frame; and repeating said steps until the importance measure fulfils a stop criterion (50). In the method, the step of determining an importance measure for the first sound frame can be executed before said third step or it can be executed between said third and fourth step. Said method further includes the step of: setting the third sound frame to the first sound frame, when the importance measure fulfils said stop criterion. This enables for that only necessarily sinusoidal components are extracted for use in a subsequent compression.
    • 本发明涉及一种确定(10)表示正弦分量的第二声音帧(20)和表示来自所提供的第一声音帧的残差的任选的第三声音帧(30)的方法,所述方法包括以下步骤:确定正弦曲线 非提取组件中第一个声音帧中的分量; 确定第一声音帧的重要性度量(40); 从第一声音帧提取正弦分量,并将正弦分量合并在第二声音帧中; 并重复所述步骤,直到重要性测量满足停止标准(50)。 在该方法中,可以在所述第三步骤之前执行确定第一声音帧的重要性度量的步骤,或者可以在所述第三和第四步骤之间执行步骤。 所述方法还包括以下步骤:当重要性测量满足所述停止标准时,将第三声音帧设置到第一声音帧。 这使得只有必要的正弦分量被提取用于随后的压缩。

    • Coding of an audio signal (x) represented by a respective set of sampled signal values for each of a plurality of sequential segments is disclosed. The sampled signal values are used to determine sinusoidal components (CS) for each of the plurality of sequential segments. The sinusoidal components (CS) are subtracted from the sampled signal values to provide a set of values (s1, s2) representing afirst residual component (x3) of the audio signal. The first residual component (x3) is conditioned (18) to remove selected tonal components and to provide a set of values (s1′, s2′) representing a second residual component (x3′) of the audio signal. The second residual component is modelled (14) by determining noise parameters (CN) approximating the second residual component (x3′); and an encoded audio stream (AS) is generated including the noise parameters (CN) and the codes representing the sinusoidal components (CS).
    • 公开了由多个连续段中的每一个的相应的一组采样信号值表示的音频信号(x)的编码。 采样的信号值用于确定多个连续段中的每一个的正弦分量(CS)。 从采样的信号值中减去正弦分量(CS),以提供表示音频信号的第一残差分量(x 3)的一组值(s 1,s 2)。 对第一残余分量(x 3)进行调节(18)以去除所选择的音调分量,并提供表示音频信号的第二残余分量(x 3')的一组值(s 1',s 2')。 通过确定近似第二残余分量(x 3')的噪声参数(CN)来对第二残差分量进行建模(14)。 并且生成包括噪声参数(CN)和代表正弦分量(CS)的代码的编码音频流(AS)。
