Support for external passive MIC acquisition of audio information: this means that the device can accept audio information input from an external passive microphone. Passive microphones typically require an external power source to power them, but they typically have higher sound fidelity and clarity than active microphones.
Support for listening audio information: This means that the device can play or transmit the audio information it has collected so that the operator can hear or monitor the audio.
Noise suppression: This is a function that filters or reduces ambient noise, making the audio information collected clearer and higher quality. For example, if the device is used in a noisy environment, noise suppression can help reduce ambient noise and make speech or music more audible. The basic way MIC collects audio information is as follows:
Sound sensing: MIC is a sound sensing device that can sense sound within a certain range and convert it into an electrical signal.
Conversion of sound into electrical signals: When the sound is sensed, the electronic components inside the MIC convert the sound into electrical signals.
Data transmission: After the electrical signal is processed, the data can be transmitted to the computer, audio processing equipment and other terminal equipment for storage or processing through the interface or wireless transmission.
In the actual acquisition process, the audio data is generally sampled, quantified, encoded and other processing through the sound card or audio processing equipment for better storage and application.
