You can make professional recordings with an audio recorder. The compact size allows you to take it with you everywhere and you can record a fragment in high quality at any time. An audio recorder is especially useful for studio productions, concert recordings, and interviews. Pay attention to the directional characteristic of the audio recorder. An omnidirectional microphone records sound from any direction. A bidirectional microphone only picks up sound from the front and back. Memory is also important. The more memory, the more recordings you can make.
