[0086] 感知域(Perceptual domain)处理 [0086] perceptual domain (Perceptual domain) processing

[0087] 近来,感知域处理已经被发明,其考虑了取决于音频信号的再现水平的音频的感知的变化。 [0087] Recently, perceptual domain processing has been invented, which takes into account the change in perceived depending on the reproduction level of the audio signal of audio. 表示的时间采样的音频信号被预处理以便产生指示多个频带(临界频带)内的信号电平的时变谱,例如,40个带,每个带由频带编号表示,并且随时间块变化。 When the audio signal representing the sampling time is pretreated to produce a signal indicative of a plurality of frequency bands within the level (critical band) varying spectrum, for example, 40 bands, each band is represented by a band number, and change over time block. 可以以许多方式产生音频信号的时变谱,但是有利地,带被分隔以便模拟人类听觉的频率分辨率。 When the audio signal may be generated in many ways varying spectrum, but advantageously, the belt is separated in order to simulate the frequency resolution of human hearing. 计算称为激励信号的量,其接近在时间块期间在临界频带处沿着人类的内耳的基底膜的能量的分布。 Calculating an amount called the excitation signal, which is close to the distribution of energy during time block along the basilar membrane of the human inner ear at critical band. 虽然还可以使用其它变换,诸如修改的离散余弦变换(MDCT),但是通过使用模拟音频透过人类的外耳和内耳的滤波器的频率响应以及带通滤波器的所选择的组(例如,选择为模仿在所关心的每个临界频带处沿着人类耳朵中的基底膜观察的临界频带滤波的带通滤波器)来计算音频信号的运行的短时离散傅里叶变换(STDFT),从而可以有效地实现感知域激励。 Although other transformations may also be used, such as a modified discrete cosine transform (the MDCT), but by using the selected set through the analog audio frequency response of the human outer ear and inner ear filter and a band-pass filter (e.g., as selected in the critical band of each imitation of interest) to calculate a running audio signal short discrete Fourier transform (the STDFT) of the base film along the critical band filtering observed human ear bandpass filter, which can effectively realize the perceived domain excitation. 示例实施例使用具有IERB的间距的一组滤波器,结果得到总共40个带。 Exemplary embodiment uses a set of filters spaced IERB results obtained with a total of 40.

[0088] 具有音色保持(timbre preservation)的失真减小的多带压缩器 [0088] Voice holder having distortion (timbre preservation) reduced multiband compressor

[0089] 在回放装置中,音频回放可以被可感知地失真,并且通常随着回放期间回放水平增大而剧烈地失真。 [0089] In the playback device, audio playback can be distorted perceptible, and generally increases as the playback level during playback violently distorted. 该失真时常是针对回放装置频率相关的。 This distortion is often a playback apparatus for a frequency dependent. 校正滤波的一个形式是在回放之前将多带压缩应用于音频信号以便减小失真并且努力使回放水平最大化。 It is in the form of a correction filter before playback of the multi-band compression to the audio signal to reduce distortion and efforts to maximize the level of the playback. 一个简单方法包括指定失真阈值,其针对压缩器的每个频带被指定。 A simple method comprises the specified distortion thresholds, which are specified for each frequency band compressor. 压缩器将不同的增益值独立地应用于每个频带以便确保输出信号不超过对应失真阈值中的任何一个。 Compressor different gain values ​​independently applied to each frequency band in order to ensure that the output signal does not exceed a threshold value corresponding to the distortion of any.

[0090] 改善的一组校正滤波器包括多带压缩器中的音色保持。 [0090] The improved set of correction filters comprises a multi-band compressor in the holding tone. 音色保持通过根据(i)针对频带的各自的固定的阈值以及至少部分地根据(ii)第二频带中的音频信号水平(数字还是模拟音频信号)以及(iii)第二频带中的固定阈值确定多个频带中的每一个中的时变阈值来实现。 Voices are determined (digital or analog audio signal) and a fixed threshold (iii) a second frequency band to pass in accordance with (i) a respective fixed threshold value for the band and at least in part on the audio signal level (ii) a second band when each of the plurality of frequency bands threshold achieved. 因此,每个时变阈值是输入信号自适应的。 Thus, each time varying input signal threshold is adaptive. 如果特定的频带由于在其固定阈值之上(或者,接近固定阈值)而接收显著的增益减小,则一个或更多个其它频带的时变阈值也减少以便接收一些增益减小。 If the specific frequency band due to the above fixed threshold (or, close to the fixed threshold value) received significant gain is reduced, when the one or more other bands is reduced so as to change the threshold number of receiving gain is decreased.

[0091] 应用这种音色保持的多带压缩器校正滤波的一个示例实施例包括针对第一频带提供或者确定固定阈值以及确定第一频带内的音频信号的第一水平。 One example of [0091] application of this tone multi-band compressor holding correction filter embodiment includes determining fixed threshold or providing for the first frequency band and determining a first level of the audio signal within the first frequency band. 第一水平能够小于固定阈值。 The first level can be less than a fixed threshold. 该方法进一步包括还针对第二频带确定音频信号的第二水平,以及通过使用第二水平针对第一频带计算时变阈值。 The method further comprises further determining a second level for a second frequency band audio signal, and a variable threshold for the first frequency band is calculated by using the second level. 时变阈值小于固定阈值。 Variable threshold is less than a fixed threshold. 该方法包括将第一频带内的音频信号衰减到等于或小于时变阈值,或者可替代地,随着接近时变阈值而越发衰减第一频带内的音频信号。 The method comprises the attenuated audio signal in a first frequency band to a varying threshold or less, or alternatively, as close to the threshold becomes increasingly attenuated audio signal in the first frequency band. 能够根据每个频带中的音频输入信号和其相应的固定阈值的平均差别计算时变阈值。 The threshold value can be changed when the average difference between the audio input signals in each frequency band and its corresponding fixed threshold is calculated. 可选地,能够进一步确定针对第二频带的第二固定阈值。 Alternatively, it is possible to further determine a second fixed threshold value for the second frequency band. 音频信号的第二水平能够超过第二固定阈值,结果得到将第二频带内的音频信号衰减到第二固定阈值。 The second level of the audio signal exceeds a second fixed threshold value can be, the resulting attenuated audio signal in a second frequency band to a second fixed threshold value. 用于实现这种方法的一组校正滤波器包括多带滤波器组(filterbank)、压缩函数元件以及至少一个音色保持元件。 A set of correction filters for implementing such a method comprises a multi-band filter bank (filterbank), the compression function element and at least one retaining element tone. 每个压缩函数元件能够专用于频带。 Each element can be a compression function dedicated to a frequency band. 音色保持元件耦接到多带滤波器组和压缩函数元件。 Voice retaining element is coupled to the multi-band filter banks and compression function element. 音色保持元件接收针对每个频带的固定阈值并且提供针对每个频带的时变阈值。 Voice holding member receives and provides an adjustable threshold for each frequency band for each frequency band of a fixed threshold. 针对频带的时变阈值通过频带外的音频信号的水平部分地确定。 For time-varying threshold level is determined by the band part of the audio signal outside the band.

[0093] 用于匹配目标响应的逆滤波 [0093] In response to match the target inverse filter

[0094] 校正滤波的另一个形式应用逆滤波器以便改变回放系统的扬声器的频率响应,致力于使逆滤波的扬声器输出与目标频率响应匹配。 Another form of [0094] the application of the inverse filter correction filter in order to vary the frequency response of the speaker of the playback system, dedicated to the speaker and the target output frequency response of the inverse filter match. 如在上面描述的基于感知处理中,该方法被应用于"临界频带"一根据感知促动的考虑确定的全频率范围的频带。 As described above, based on sensing process, the method is applied to the "critical band" according to a perceptual frequency band considering the determined actuation of the entire frequency range. 典型地,划分可听频率范围的临界频带具有随着横过(across)可听频率范围的频率增大的宽度。 Typically, dividing the critical band of the audible frequency range having as transverse (across) the frequency of the audible frequency range increasing width. 该方法使用"临界分带的(critically banded)"数据,暗示全频率范围包括临界频带,并且数据包括子集,每个子集由表示临界频带中的不同的一个中的音频内容的数据组成。 The method uses a "critical band division (critically banded)" data, suggesting the entire frequency range including critical bands, and the data comprises a subset, each subset of data of the audio content critical band represents a different composition.

[0095]目标频率响应可以是平坦的或者可以具有其它一些预定形状。 [0095] The target frequency response may be flat or may have some other predetermined shape.

[0096] 在一些实施例中,校准方法包括针对回放系统的扬声器确定逆滤波器。 [0096] In some embodiments, the calibration method includes determining an inverse filter for loudspeaker playback system. 校准包括: 测量在听音布置中的许多不同的空间位置中的每一个处的扬声器的冲激响应,对测量的冲激响应进行时间对准和求平均以便确定平均的冲激响应,以及使用临界频带平滑化以便根据平均的冲激响应和目标频率响应确定逆滤波器。 Calibration comprising: a speaker impulse at each of a number of different spatial arrangement in the listening position measurement in response to the measured impulse responses are time aligned and averaged to determine an average of the impulse response, and using critical band smoothing in response to determining the inverse filter impulse response and the average target frequency. 例如,临界频带平滑化可以被应用于平均的冲激响应以及可选地在确定逆滤波器期间也被应用于目标频率响应,或者可以被应用于确定目标频率响应。 For example, critical bands mean the smoothing may be applied to the impulse response during and optionally determining the inverse filter is also applied to the target frequency response, or may be applied to determine the target frequency response. 在多个空间位置处的冲激响应的测量能够确保针对各种收听位置确定扬声器的频率响应。 In the measurement of the impulse response at a plurality of spatial positions can be secured to determine the frequency response of the loudspeaker for various listening positions. 在一些实施例中,测量的冲激响应的时间对准通过使用实倒谱(real cepstrum)和最小相位重构(minimum phase reconstruction)技术来执行。 In some embodiments, the impulse response measured time aligned real cepstrum (real cepstrum) by using the reconstructed and the minimum phase (minimum phase reconstruction) techniques.

[0097] 在一些实施例中,平均的冲激响应经由离散傅里叶变换(DFT)或者其它时域到频域的变换而被转换为频域。 [0097] In some embodiments, the average impulse response via the Discrete Fourier Transform (DFT) or other time domain to the frequency domain is transformed into a frequency domain. 结果得到的频率分量表示测量的平均的冲激响应。 The results obtained are shown mean frequency component of the impulse response measured. 在每个变换库(bin)中的这些频率分量被组合成较少数量的临界频带(例如20个带或者40个带)中的频域数据,如对于其它感知域处理一样。 These frequency components of the frequency domain data in each transform library (bin) and are combined into a smaller number of critical bands (e.g., band 20 or strip 40) is such as to other perceptual domain processing. 平均的冲激响应数据的分带成临界分带数据被设计成模仿人类听觉系统的频率分辨率。 The average sub-band impulse response data into sub-band data is the critical designed to mimic the frequency resolution of the human auditory system. 典型地通过向其应用合适的临界分带滤波器来对变换频率库中的频率分量进行加权以及通过将对于带加权的数据求和来产生对于每个临界频带的频率分量,从而执行分带。 Is typically performed by applying a suitable thereto critical frequency component sub-band filter frequency transformation library by weighting and summing the frequency components generated for each critical band with respect to the weighted data, thereby performing sub-band. 典型地,这些滤波器表现出大约圆形的(rounded)指数形状并且以等效矩形带宽(Equivalent Rectangular Bandwidth,ERB)的尺度被均勻地分隔。 Typically, these filters exhibit approximately circular (Rounded) exponential shape and are Equivalent Rectangular Bandwidth (Equivalent Rectangular Bandwidth, ERB) scale is evenly spaced. 临界频带的频率上的间距和交迭提供了与人类听觉系统的能力相当的所测量的冲激响应的规则化(regularization)的程度。 Spacing and overlap in the frequency critical bands provides a degree of regularization (regularization) impulse response and the ability of the human auditory system corresponding to the measured. 临界带滤波器的应用是临界带平滑化的一个示例(临界带滤波器典型地将感知上不相关的冲激响应的不规则平滑掉,使得所确定的逆滤波器不需要花费资源来校正这些细节)。 Application of critical band filter is one example of the critical band smoothing (typically critical band filter to smooth out the irregularities of the impulse response of the perceptually irrelevant, so that the determined inverse filter to correct these resources need to spend detail).

[0098] 用于确定逆滤波器的值是根据频率窗口(例如,临界频带)中的目标响应和平均的冲激响应(例如根据其平滑化的版本)而确定的。 Inverse filter value [0098] is used to determine the frequency window (e.g., critical bands) and the average response to the target impulse response (e.g., according to its smoothed version) determined. 临界分带的冲激响应数据被用来寻找实现期望的目标响应的逆滤波器。 The critical points with impulse response data are used to find the inverse filter to achieve a desired target response. 在一些实施例中,为了在使用逆滤波器时维持相等的响度,逆滤波器优选地针对其频谱代表常见声音的参考信号(例如粉红噪声)规格化(normalize)。 In some embodiments, in order to maintain an equal loudness inverse filter during use, for which the inverse filter is preferably a common spectrum representative of a sound reference signal (e.g. pink noise) normalized (normalize). [0099] 在一些实施例中,在时域中直接计算逆滤波器系数。 [0099] In some embodiments, the inverse filter coefficient is calculated directly in the time domain.

[0100] 结果得到的逆滤波器形成如在本申请中描述的应用于回放系统中的信号的校正滤波器的组。 [0100] The results obtained form a group such as an inverse filter filters the correction signal is applied to a playback system described in the present application, in the.
