If you are planning to use your microphone to record audio on the go, a digital voice recorder will help your production to be a lot more portable. Some digital voice recorders double as audio interfaces and allow for recording from an XLR mic into your computer via USB input, but if you are only planning on recording in the studio or at home, you should invest in a designated audio interface rather than a digital voice recorder. Some cheaper voice recorders don’t have the option to attach an external microphone, so make sure you look for input options when selecting a digital voice recorder.
