Comparison of sound quality of voice recorder and microphone

They should be similar. Common microphones are dynamic and condenser. If you want good sound quality and high resolution, you must use capacitors. Capacitors are all used in recording studios. The key is that the condenser microphone itself costs several hundred yuan, and the most important thing is that it requires an external power supply. A 48V phantom power supply costs nearly a hundred yuan. So you can only buy the best moving coils for two to three hundred dollars. And you said you are going out to record, so it seems that capacitive is not suitable (except of course if you have a professional camera). In addition, the object of your recording is a speech or something, so as long as it is clear and the noise is low, the main feature of the capacitor is high resolution (let’s put it this way, it means that the recorded person’s words are pronounced clearly and not muddy).

In addition, considering the portability and long battery life (less than an hour of lecture time, right?), it is recommended that you buy a voice recorder

Remember, the voice recorder is not an MP3 player. Even if it is a dynamic microphone, the sound quality is not the same. level!
