technical field

Background technique

As an essential basic function of terminal equipment products such as smartphones, recording is widely used in voice calls, sound collection and other occasions. Therefore, the quality of equipment recording will directly affect the experience of terminal equipment users.

The recording function of the terminal device is mainly realized through the audio collection of the microphone. However, the AOP (Acoustic Overload Point, Acoustic Overload Point) of consumer-grade microphones limited by terminal devices is low, and in noisy environments (for example, KTV (singing entertainment venues), concert venues, etc.), ambient sound generally occurs. The pressure level is too high, exceeding the AOP of the microphone, resulting in saturation and distortion of the recording, resulting in a series of problems such as broken sound and noise, which in turn reduces the recording quality and efficiency of the terminal device and affects the user experience.

1. In order to ensure that the high-volume recording does not break the sound, the high-sound-pressure-level microphone uses a thick microphone diaphragm material. Although the sound does not break at high volume, the sensitivity of the thick microphone diaphragm is poor. In a medium or low volume environment, recording Low amplitude and reduction degree;

2. Due to the special material process, application field and market scale of high sound pressure level microphones, the price is several times that of ordinary microphones, resulting in high cost of terminal equipment and difficult promotion.

As an electro-acoustic conversion device, speakers are conventionally used to convert electrical signals into acoustic signals. That is, as shown in FIG. 2 , the multimedia data is decoded by the DeCode module, transmitted to a DAC (analog-to-digital converter) for analog-to-digital conversion, and then amplified by a PA (power amplifier) to finally drive the speaker 211 , which will not be described in detail in this embodiment. The playback path of the speaker 211. But conversely, when the sound wave excites the speaker diaphragm, the coil moves in the magnetic field to cut the magnetic induction line, and an induced current will also be generated to realize the function of collecting sound. This current is weaker than that of traditional microphones, but the amplitude displacement of the speaker is limited, and the current signal will not be distorted.

In this embodiment, by rationally using the conventionally built-in speakers of terminal devices such as smart phones, a high-fidelity recording function in a noisy environment is effectively implemented, thereby effectively improving the recording quality and efficiency of the terminal device, thereby improving the user experience. experience.

After debugging, the audio data is finally encoded by the InCode module to generate the corresponding recording file and save it.

Step 104: Invoke the microphone channel for recording.

In this step, in response to the fact that the current audio is not distorted, the distortion debugging audio data of the preset time period is retained, and the microphone is called to collect the current audio data through the microphone, so that the recording amplitude can be fully guaranteed in a medium or low volume environment and recovery.
