摘要： An electronic device includes a communication circuit, a speaker, and a processor. The processor is configured to identify a bitrate of a first audio bitstream received via the communication circuit from an external electronic device. The processor is configured to obtain, in response to the bitrate lower than a reference value, an audio signal by executing a bandwidth extension (BWE) for the first audio bitstream based on at least one coding parameter obtained from a second audio bitstream previously received via the communication circuit from the external electronic device before the first audio bitstream. The processor is configured to obtain, in response to the bitrate higher than or equal to the reference value, the audio signal for the first audio bitstream without executing the BWE. The processor is configured to output, based on the audio signal, audio via the speaker.
