In recording, microphone plays an important role, that is, converting the pneumatic vibration that turns the sound into electric signals. Of course, a preamplifier that amplifies the microphone signals, an AD converter that converts the sound into digital signals, and the DAW software that shapes the sound. All these gears are important after the recording stage. However, these gears work with the sound which has already been converted by the microphone. This means, the quality of a microphone detemine the sound quality of the entire song.
