摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for stereophonic acoustic echo cancellation. The method includes collecting, at a same time, a first audio sample of an audio source from a first omnidirectional microphone and a second audio sample of the audio source from a second omnidirectional microphone. The method includes delaying the second audio sample by a first amount of time to yield a delayed second audio sample and combining the delayed second audio sample with the first audio sample to produce a first channel, then delaying the first audio sample by a second amount of time to yield a delayed first audio sample and combining the delayed first audio sample with the second audio sample to produce a second channel. Then the method includes outputting the first channel and the second channel as a stereo audio signal of the audio source.

摘要： The present invention utilizes pseudo-stereo for the communication of secondary information to the user of a telecommunications terminal, such as a speakerphone. In particular, the terminal utilizes a method for the presentation of secondary information to the user of the terminal in a teleconference call by adjusting the spatial properties of the monaural audio received at the user's terminal. An audio communication is modified so as to appear that the communicated audio is arriving from a particular direction in relation to the user's approximate position, wherein the direction that is assigned to the audio depends on one or more characteristics of the call participant who is originating the audio. Each characteristic of a call participant on a call can comprise, while not being limited to, the customer satisfaction of the call participant, the urgency of a need of the call participant, the group membership of the call participant, or the product ownership of the call participant.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for suppressing spatial noise based on phase information. The method transforms audio signals to frequency-domain data and identifies time-frequency points that have a parameter (e.g., signal-to-noise ratio) above a threshold. Based on these points, unwanted signals can be attenuated the desired audio source can be isolated. The method can work on a microphone array that includes two microphones or more.

摘要： A second-order adaptive differential microphone array (ADMA) has two first-order elements (e.g., 802 and 804 of FIG. 8), each configured to convert a received audio signal into an electrical signal. The ADMA also has (i) two delay nodes (e.g., 806 and 808) configured to delay the electrical signals from the first-order elements and (ii) two subtraction nodes (e.g., 810 and 812) configured to generate forward-facing and backward-facing cardioid signals based on differences between the electrical signals and the delayed electrical signals. The ADMA also has (i) an amplifier (e.g., 814) configured to amplify the backward-facing cardioid signal by a gain parameter; (ii) a third subtraction node (e.g., 816) configured to generate a difference signal based on a difference between the forward-facing cardioid signal and the amplified backward-facing cardioid signal; and (iii) a lowpass filter (e.g., 818) configured to filter the difference signal from the third subtraction node to generate the output signal for the second-order ADMA. The gain parameter for the amplifier can be adaptively adjusted to move a null in the back half plane of the ADMA to track a moving noise source. In a subband implementation, a different gain parameter can be adaptively adjusted to move a different null in the back half plane to track a different moving noise source for each different frequency subband.
摘要翻译：二阶自适应差分麦克风阵列（ADMA）具有两个一阶元件（例如，图8的802和804），每个元件被配置为将接收到的音频信号转换成电信号。 ADMA还具有（i）被配置为延迟来自一阶元件的电信号的两个延迟节点（例如，806和808），以及（ii）被配置为产生向前和向后的两个减法节点（例如，810和812）基于电信号和延迟的电信号之间的差异的向后的心形信号。 ADMA还具有（i）被配置为通过增益参数放大后向心形信号的放大器（例如814）（ii）第三减法节点（例如，816），被配置为基于前向心形信号和放大的后向心形信号之间的差异产生差分信号; 以及（iii）低通滤波器（例如，818），被配置为对来自第三减法节点的差分信号进行滤波，以产生用于二阶ADMA的输出信号。可以自适应地调节放大器的增益参数，以在ADMA的后半平面移动零点，以跟踪移动噪声源。在子带实现中，可以自适应地调整不同的增益参数以在后半平面中移动不同的零，以跟踪每个不同频率子带的不同移动噪声源。
