The first step: the microphone picks up the sound wave.
First, we need to use a microphone to pick up the sound waves, which are the sound signals.
The second step: level signal amplification.
Since the sound signal picked up by the microphone is a low level signal, we need to amplify the sound signal through a component called a microphone amplifier to convert it to a standard level.
The third step: analog to digital conversion.
The amplified sound signal is still an analog signal, and then we have to digitally convert it, which is what we call analog to digital conversion.
The fourth step: signal coding.
Because only audio files produced according to certain standard standards can be played in different digital devices and correctly restored.
So we have to convert the analog signal into a digital signal camera that the computer can handle or a computer system in the recorder to encode the signal and package the signals into an audio file.
The fifth step: decoding playback restore.
Eventually, the digital audio file is decoded and played by the audio playback device, and then restored to a sound signal through the speaker, and then changed back to the sound we can hear.
The basic process of digital recording sounds complicated but it is also very simple. It should be noted that all the links in this process will affect our final recording quality, so only by selecting good equipment and using reasonable workflow and methods can we guarantee get better sound.
