Sound recording method and device

Abstract

The invention discloses a sound recording method and a sound recording device. The sound recording method comprises the steps that a master control terminal determines a sound recording mode, terminals corresponding to all sound channels in the sound recording mode and preset position information of all of the terminals, and sends the corresponding preset position information to the corresponding terminal, wherein the terminals which correspond to all of the sound channels in the sound recording mode at least include a terminal connected with the master control terminal; when all of the terminals are positioned in preset positions in the sound recording mode, the corresponding preset position information is sent to the corresponding terminal, and the terminals which correspond to all of the sound channels in the sound recording mode at least include a terminal connected with the master control terminal; when all of the terminals are positioned in preset positions in the sound recording mode, all of the terminals are controlled to synchronously record sound of a sound source by the master control terminal, so as to obtain records from all of the terminals, and the records from all of the terminals are synthesized. According to the sound recording method and the sound recording device, double-channel or multichannel recording can be conveniently realized through at least two terminals, thereby improving the use experience of an end user.

Description

technical field [0001] The invention relates to audio recording technology, in particular to a sound recording method and device. Background technique [0002] Stereo is the use of two or more independent sound paths, presented on a pair of speakers arranged in a symmetrical fashion. People can hear stereo because the sound source has a loudness difference (sound pressure is inversely proportional to the propagation distance) and a phase difference (the same sound source reaches the two ears at different times, and the vibration state is also different) relative to the two ears. The human brain will judge the direction and distance of the sound source based on the reflection and diffraction of the head and pinna. Similar to the principle of human hearing stereo, two microphones (MIC) can be used to record the loudness difference and phase difference of the same sound source, which is the principle of two-channel stereo recording. [0003] Although the sound quality and sou...

Problems solved by technology

To achieve dual-channel or multi-channel recording, at least two recording microphones need to be configured on the mobile phone. This will increase the cost of the equipment, and the hardware structure of the mobile phone needs to be changed, so the versatility is poor.
