Embodiment Construction
[0026] The embodiment of the present invention fully considers the influence of the recording distance on the target sound characteristics, and proposes two different recording control technologies according to the recording distance, which will be described in detail below with reference to the accompanying drawings.
[0027] 1. Proximity mode
[0028] The proximity mode can also be called the dictation mode, that is, the recording distance is relatively short, and the sensitivity of the sound collection unit can be set to be low, such as recording during an interview or a self-report. At this time, when the sound wave reaches the sound collection unit of the recording device, it is a spherical wave, and the sound wave intensity of the spherical wave is inversely proportional to the square of the distance. Generally, the recording device has two or more sound collection units. If the intensity ratio of the sound collected by the unit satisfies the characteristics of the spher...
