Abstract: A method and a device for improving audio processing performance are provided. In some embodiments, the method includes: acquiring audio data in an audio call in a terminal; processing the audio data by utilizing an audio processing algorithm, to obtain a characteristic parameter of the audio data; analyzing the processing quality of the audio data according to the characteristic parameter of the audio data; and if the processing quality of the audio data does not reach a preset quality standard, optimizing the audio processing algorithm by utilizing optimization data matching the terminal.

Abstract: The invention relates to a heat exchanger apparatus comprising at least one metal sheet (10) (e.g. aluminium), and preferably a plurality in a stack. Each metal sheet (10) has a corrugated surface, with fabric covering at least a portion of one surface of the metal sheet to promote evaporation. A wetting agent (e.g. LiCl/Polyvinyl-Alcohol (PVA) solution) is provided in the fabric to promote wetting of the fabric, and also acts as an anti-microbial agent. The fabric preferably covers all of the corrugated surface, and two planar portions are provided above and below the corrugated surface respectively. In use, the heat exchanger apparatus is disposed with a long side vertical and the corrugated surface is disposed on a middle portion, the upper planar portion is contiguous with an air outlet, and/or the lower planar portion is contiguous with an air inlet. In a preferred embodiment, the corrugated surface has in cross-section a profile of a periodic waveform, wherein the peak-to-peak distance is 11.

Abstract: A controller can include a signal generator configured to provide an input signal to a modulator. The controller can be configured to generate a modulator compensation parameter in response to a modulated feedback signal corresponding to an output of the modulator. The controller can also be configured to generate a power amplifier predistortion signal in response to an amplified feedback signal corresponding to an output of a power amplifier coupled to the modulator.

Abstract: To-be-commented video data is received by a terminal device, and a video sequence number of the to-be-commented video data is determined, which steps further include comprising, by the video data, a first correlation 2-tuple of a global base sequence number and the video sequence number, in which a sequence number of a live voice in the video data is the global base sequence number, and the video sequence number of the video data is determined according to the global base sequence number; and determining a video sequence number of the to-be-commented video data according to the first correlation 2-tuple. The to-be-commented video data is played, a commentary voice is acquired, and a correspondence between a voice sequence number of the commentary voice and the video sequence number is determined. The correspondence between the voice sequence number and the video sequence number is sent to a video playback end.

Abstract: 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.
