Method, application, and device for audio signal transmission

A computer system comprising a mobile terminal, the mobile terminal having:

• one or more processors;
• memory;
• and
• one or more programs modules stored in the memory and configured for execution by the one or more processors, the one or more program modules including:
• a receiving module configured to receive an audio signal transmission request from a user of the mobile terminal;
• a recording module configured to initiate a recording session in a recording program to record audio signals captured by the mobile terminal into audio frames in an audio file;
• an encoding module having a codec determination unit and an encoding unit, wherein:
• during the recording session:
• the encoding unit is configured to encode a respective predefined sequence of audio frames in the audio file using a first audio codec,
• the codec determination unit is configured to measure an amount of processing time associated with the encoding,
• if the amount of processing time associated with the encoding is less than a predefined threshold, the encoding unit is configured to continuously encode remaining audio frames in the audio file using the first audio codec,
• if the amount of processing time associated with the encoding is equal to or greater than the predefined threshold, the encoding unit is configured to encode remaining audio frames in the audio file using a second audio codec;
• and
• a caching module configured to cache the encoded predefined sequence of audio frames and the remaining audio frames in the memory;
• a transmission module configured to transmit the encoded predefined sequence of audio frames and the encoded remaining audio frames in the memory to a remote server after a play time of the cached audio frames exceeds a predefined time period.

A non-transitory computer readable storage medium having stored therein one or more instructions, which, when executed by a mobile terminal, cause the mobile terminal to:

• receive an audio signal transmission request from a user of the mobile terminal;
• initiate a recording session in a recording program to record audio signals captured by the mobile terminal into audio frames in an audio file;
• during the recording session:
• encode a respective predefined sequence of audio frames in the audio file using a first audio codec and measure an amount of processing time associated with the encoding;
• if the amount of processing time associated with the encoding is less than a predefined threshold, continuously encode remaining audio frames in the audio file using the first audio codec;
• if the amount of processing time associated with the encoding is equal to or greater than the predefined threshold, encode remaining audio frames in the audio file using a second audio codec;
• cache the encoded predefined sequence of audio frames and the remaining audio frames in the memory;
• and
• transmit the encoded predefined sequence of audio frames and the encoded remaining audio frames in the memory to the remote server after a play time of the cached audio frames exceeds a predefined time period.
