An audio data processing method and apparatus, a device, and a storage medium that can obtain, in a game voice mode, a signal processing result associated with a first pre-signal processing policy in an application layer of a service application; control, in the application layer according to the signal processing result, a turned-on/turned-off state of a second optimization component in a second pre-signal processing policy in a terminal system layer, or a turned-on/turned-off state of a first optimization component in the first pre-signal processing policy, a first optimization component turned on in the first pre-signal processing policy being different from a second optimization component turned on in the second pre-signal processing policy; and obtain uplink voice data of a first user in the game voice mode, and perform voice optimization on the uplink voice data based on the turned-on first optimization component and the turned-on second optimization component.

Audio data processing method and apparatus, device, and storage medium

An audio processing method and apparatus are provided. The method includes: obtaining a voice audio of a first game user and spatial position information of a first virtual object controlled by the first game user in a game scene; performing conversion processing on the voice audio of the first game user to obtain a target audio matching a character attribute of the first virtual object; and transmitting the target audio and the spatial position information of the first virtual object to a second terminal such that the second terminal plays the target audio according to the spatial position information of the first virtual object, a second virtual object controlled by a second game user using the second terminal and the first virtual object being in a same game scene.

Audio processing method and apparatus

Embodiments of this disclosure provide a speech enhancement method and apparatus, an electronic device, and a computer-readable storage medium. The method includes: obtaining a clean speech sample; decomposing the clean speech sample to obtain a first sparse matrix and m base matrices, values in the first sparse matrix being all positive numbers, and m being a positive integer greater than 1; obtaining, according to the first sparse matrix and a weight matrix of a target neural network, state vectors of neurons in a visible layer of the target neural network; and updating the weight matrix according to the state vectors of the neurons in the visible layer and the clean speech sample, to obtain a deep dictionary used for speech enhancement.

Speech enhancement method and apparatus, electronic device, and computer-readable storage medium

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.

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.
