Abstract
The present invention relates to audio recording, and in particular to a method for audio recording and conversion of smart headset. The smart headset establishes communication with the mobile terminal, and the mobile terminal sends an instruction to the smart headset to start recording. The smart headset splits audio data into two channels, wherein one is sent to the SPEAK end of the smart headset and played, the other is sent to the mobile terminal after being compressed and packaged. The smart headset uses its cache memory to cache the audio data packets, and determines whether it has received the confirmation signals from the mobile terminal within the response time limit. If the smart headset has received the confirmation signals from the mobile terminal within the response time limit, it will clear the corresponding audio data packets from the cache memory, otherwise re-send the audio data packet cached.
