Provided is a method for detecting an audio input interface, comprising: acquiring input signals of every one of audio input interfaces; acquiring energy values of said input signals of every one of said audio input interfaces, and acquiring an interface identification of the audio input interface of which the energy value is the maximum among the energy values; adding said interface identification acquired herein into an identification sequence in an order by acquiring time; and identifying the audio input interface, of which the interface identification is saved most often in said identification sequence, as a valid audio input interface. Also provided is a system for detecting an audio input interface. The present disclosure is capable of effectively identifying the audio input interface connected to the microphone that the user is using, so that the user does not need to switch manually.

Method, system and computer storage medium for detecting an audio input interface

Systems and methods are provided for data transmission. For example, packet loss is detected based on at least information associated with a first data packet; and in response to packet loss being detected, a packet-retransmission request is sent to a data-transmission terminal and the packet-retransmission request is repeatedly sent to the data-transmission terminal during a retransmission life-cycle associated with the first data packet, the packet-retransmission request including a first identification of the packet-retransmission request.

Systems and methods for data transmission

Audio processing methods and apparatus are provided. An audio processing method may include: receiving audio data packets; buffering the audio data packets to a buffer; reading the audio data packets from the buffer and playing the audio data packets; accumulating an actual total playing time length and a total sampling time length of the audio data packets that currently have been read from the buffer and have been played; and suspending reading and playing, when a sum of sampling time lengths of audio data packets that are buffered and unread in the buffer is less than or equal to a first threshold, until a sum of sampling time lengths of the audio data packets in the buffer that are unread is greater than or equal to a current network jitter estimated value.

Audio processing method and apparatus

Systems and methods are provided for audio encoding. For example, first quantization encoding is performed on audio data associated with a current frame of an audio data stream to obtain first quantization-encoded data; second quantization encoding is performed on the audio data to obtain second quantization-encoded data; the first quantization-encoded data is coupled to the current frame of the audio data stream; and the second quantization-encoded data is coupled to a next frame of the audio data stream.

Systems and methods for audio encoding and decoding

A method, apparatus and system for acquiring an input event in a computer system comprising different priorities for processes are provided, the method comprising: executing a servant process and a master process, wherein the servant process comprises a higher priority than the master process and an input event list; and upon the servant process acquiring an input event and determining that the input event is in the input event list, the servant process transmitting the input event to the master process. A servant process with a high priority is used to acquire input events, which facilitates the operation of other processes and enhances process execution efficiency.

Method, apparatus and system for acquiring input events

Systems and methods are provided for echo reduction. For example, first audio data associated with a current time unit is obtained, the first audio data being generated by an audio-acquisition device of a receiver based on at least information associated with a first audio signal acquired by the audio-acquisition device and a second audio signal output from an audio-playback device of the receiver, the second audio signal being output from the audio-playback device of the receiver based on at least information associated with second audio data transmitted previously by a sender before the current time unit; third audio data transmitted by the sender during a second time unit preceding the current time unit is obtained; and fourth audio data is obtained by performing echo reduction on the first audio data based on at least information associated with the third audio data.

Systems and methods for echo reduction

An audio playback method is provided. The method includes identifying a captured audio data frame according to a type of the audio data frame and sending the identified audio data frame to an audio receiving end. The method also includes receiving the audio data frame that is identified according to the type of the audio data frame and determining the type of the audio data frame and evaluating network transmission status based on the identification. Further, the method includes adjusting a threshold value of a jitter buffer that is used to cache the audio data frame when the type of the audio data frame is a music frame and evaluation result of the network transmission status does not meet a preset transmission baseline condition.
