Abstract

The invention discloses a device and a method for recording through earphone microphone jack expansion. The device is provided with an earphone microphone plug and a circuit, and the earphone microphone plug is used for being accessed in an earphone microphone jack; the circuit is used for being connected with the earphone microphone plug, and four joints of the earphone microphone are connected into the earphone microphone jack and are used for expanding sound transmission on the basis of the circuit. The method comprises the following steps: S1, introducing a sound channel signal; S2, carrying out voltage dividing and sound mixing on the introduced sound channel signal; S3, carrying out level signal matching and attenuation on the signal after voltage dividing and sound mixing; and S4, introducing a sound frequency signal after matching and attenuation into the input end of a microphone to reach recording and sound transmission. The problems of low antijamming capability and large noise when system sound is captured by using a traditional recording manner are solved, and application software and program for sound capture, transmission and recording can be helped to capture high-quality sound signals from the microphone by using the device and the method.

Description

technical field [0001] The invention relates to audio signal processing technology, in particular to an internal recording device and method extended through an earphone microphone jack. Background technique [0002] On most personal computers and smart devices, such as Android phones, the hardware does not currently provide the function of system sound internal recording. Most system sound capture, transmission, monitoring, and recording applications can only pick up speakers from external microphones. However, it will mix external noise into the audio signal at the same time, and the signal quality is very poor, which is difficult to meet the actual needs of high-quality audio processing. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide an internal recording device and method extended through the earphone microphone jack, which solves the problem of poor anti-interference ability and larg...
